Multidrug-resistant tuberculous spondylitis is a global health issue, especially in developing nations, and non-specific symptoms lead to delay in identification, treatment, and potential disability in children. Radiology plays a crucial role in diagnosing tuberculous spondylitis, which in turn might lead to effective treatment, prevention of disability and improved patient outcomes. Our case involved a 20-month-old malnourished child presented with paraparesis, revealing a history of contact with parental multidrug-resistant tuberculosis. Multimodality radiological examinations, including conventional radiography, CT, and MRI revealed extensive disease of the spine with disc involvement, large paravertebral abscess, and kyphotic deformity which produced neurological deficits, necessitating both anti-tuberculosis regimen and surgical intervention. Radiological examinations have a pivotal role in diagnosing, evaluating and guiding timely management of multidrug-resistant tuberculous spondylitis. Prompt diagnosis of the condition is crucial in order to prevent potentially severe complications, which contribute significantly to morbidity. Our case demonstrated the importance of radiology in diagnosing extensive spine involvement of the disease causing neurological deficits. Furthermore, radiology also helps in managing tuberculous spondylitis to prevent future disability in a child patient of a developing country. This case highlights the crucial significance of radiological imaging in the diagnosis and management of pediatric tuberculous spondylitis in impoverished nations. The patient's complex medical history highlights the socioeconomic factors contributing to tuberculosis burden. Early and comprehensive radiological assessment, together with collaboration between radiologists and clinicians, is vital for timely intervention and improved outcomes in pediatric tuberculous spondylitis cases to prevent the impact of this debilitating disease on children.

Review
BACKGROUND
Intramedullary melanocytomas are exceedingly rare, with only twenty-four cases reported up to now. They present as local invasive tumors despite their benign biological behavior. Attempting a complete safe resection often results in severe post-operative neurological deficits, as in our case presented here.
METHODS
A systematic review was conducted across the PubMed and Scopus databases including studies published till February 2024.
RESULTS
A total of 19 studies were included, encompassing 24 cases. A similar distribution between sexes was noted (M:F 13:11), with ages ranging from 19 to 79 years. The thoracic segment was most affected, and intermediate-grade melanocytoma (19 cases) was the most common histotype. Radiographically, intramedullary melanocytomas usually appear as hyperintense hemorrhagic lesions peripheral to the central canal with focal nodular enhancement. Intraoperatively, they are black-reddish to tan and are tenaciously adherent lesions. In the sampled studies, IONM employment was uncommon, and post-operative new-onset neurological deficits were described in 16 cases. Adjuvant RT was used in four cases and its value is debatable. Recurrence is common (10 cases), and adjuvant therapies (RT or repeated surgery) seem to play a palliative role.
CASE PRESENTATION
A 68-year-old woman presented with a three-year history of worsening spastic paraparesis and loss of independence in daily activities (McCormick grade 4). An MRI revealed an intramedullary tumor from Th5 to Th7, characterized by T1-weighted hyperintensity and signs of recent intralesional hemorrhage. Multimodal neuromonitoring, comprising the D-Wave, guided the resection of a black-tan-colored tumor with hyper-vascularization and strong adherence to the white matter. During final dissection of the lesion to obtain gross total resection (GTR), a steep decline in MEPs and D-Wave signals was recorded. Post-operatively, the patient had severe hypoesthesia with Th9 level and segmental motor deficits, with some improvement during neurorehabilitation. Histopathology revealed an intermediate-grade melanocytoma (CNS WHO 2021 classification). A four-month follow-up documented the absence of relapse.
CONCLUSIONS
This literature review highlights that intramedullary T1 hyperintense hemorrhagic thoracic lesions in an adult patient should raise the suspicion of intramedullary melanocytoma. They present as locally aggressive tumors, due to local invasiveness, which often lead to post-operative neurological deficits, and frequent relapses, which overwhelm therapeutic strategies leading to palliative care after several years.

BACKGROUND
Cardiac myxomas present a diagnostic challenge due to their ability to mimic various cardiovascular and systemic conditions. Timely identification is crucial for implementing surgical intervention and averting life-threatening complications.
CASE PRESENTATION
We reported the case of a 49-year-old male patient who presented sudden legs weakness and slurred speech and was admitted 10 h later in emergency department. Physical examination was significant for paraparesis and paraphasia. Cardiac and carotid auscultation was normal. CT brain revealed multiple acute ischemic strokes and MRA was suggestive of cerebral vasculitis. As pre-therapy assessment, the EKG revealed no electrical abnormalities and the chest X-ray showed signs of left atrial enlargement. Transthoracic and transesophageal echocardiography showed a left atrial mass attached to the interatrial septum, measuring 9*5*4 cm and extending into the left ventricular cavity during diastole, which suggested the diagnosis of left atrial myxoma. The patient was referred for open-heart surgery and histopathological examination confirmed the diagnosis of myxoma. The patient weaned off from cardiopulmonary bypass and the postoperative period was uneventful.
CONCLUSION
We reported an interesting case with an unusual and misleading neurological presentation of a cardiac myxoma. The unpredictability of serious complications occurrence must awaken our medical flair, for an early diagnosis among a long list of differentials.

BACKGROUND
Human T-cell Leukemia Virus type-1 (HTLV-1) -associated myelopathy causes sufferers to experience changes in several aspects of their lives. Gaining a deeper understanding of these changes can help healthcare professionals improve care, enhance strategic decision-making, meet expectations, and manage patients effectively. However, there is no information about the experience and problems of patients with HTLV-1-associated myelopathy/tropical spastic paraparesis in Iran. Therefore, this study aimed to explain the lived experience of patients with HTLV-1-associated myelopathy/tropical spastic paraparesis.
METHODS
This qualitative study used hermeneutic phenomenology in 2022 in Mashhad, Iran. Participants were selected using purposeful sampling. Data were collected through 21 semi-structured in-depth interviews with 20 eligible patients with HTLV-1-associated myelopathy/tropical spastic paraparesis. The data were analyzed in MAXQDA/2020 using the six stages proposed by Van Manen.
RESULTS
The main concept of "Reduced self-sufficiency and social dignity" emerged from the narratives of the patients, which included three main categories "Disruption of desirable personal and social life", "reduced perception of role competencies", and "obligatory unpleasant lifestyle changes".
CONCLUSION
HTLV-1-associated myelopathy/tropical spastic paraparesis slowly makes patients feel insufficient and causes a sense of degradation in dignity. The disease can fundamentally change personal and social life. Thus, due to its incurability and progressiveness, palliative care should be provided to them to live with dignity.

A 57-year-old man presented with subacute-onset paraparesis, bilateral dysesthesia in his lower extremities, and bladder/bowel disturbance six weeks after being infected with SARS-CoV-2 infection (COVID-19). A neurological examination suggested transverse myelitis at the level of the lower thoracic spinal cord. However, repeated spinal magnetic resonance imaging (MRI) showed no abnormalities in the spinal cord. Laboratory and cerebrospinal fluid (CSF) tests ruled out other etiologies of myelitis, eventually suggesting COVID-19-associated myelitis. Aggressive immunosuppressive therapy, started soon after hospitalization, dramatically improved his symptoms. Early aggressive immunosuppressive therapy should therefore be considered in cases of MRI/CSF-negative myelitis associated with COVID-19.

Surgical Neurology International 2024In a 31-year-old male, psoriasis vulgaris (PV) of the skin caused paraparesis attributed to a L3-L4 epidural spinal abscess that required emergent surgical decompression.
BACKGROUND
In a 31-year-old male, psoriasis vulgaris (PV) of the skin caused paraparesis attributed to a L3-L4 epidural spinal abscess that required emergent surgical decompression.
CASE DESCRIPTION
A 31-year-old male presented with lower back pain and cauda equina compression attributed to a magnetic resonance-documented L34 enhancing lesion consistent with a spinal epidural abscess (SEA). The skin over the L3-L4 level revealed severe PV that proved to be the likely etiology of the right-sided paraspinal muscle abscess, infected right L3-L4 facet joint, and SEA. At surgery, the foci of infection were excised/decompressed, and cultures grew methicillin-susceptible Staphylococcus aureus. Following surgery, the patient was improved and was treated with appropriate antibiotic therapy.
CONCLUSION
PV caused a L3-L4 epidural spinal abscess and cauda equina compression in a 31-year-old male who was successfully treated with operative decompression and appropriate antibiotic management.

INTRODUCTION
Human T-cell Lymphotropic virus type 1 (HTLV-1) belongs to retroviridae which is connected to two major diseases, including HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and Adult T-cell leukemia/lymphoma (ATLL). This study aims to investigate the mRNA expressions of key proteins correlated to T-cell activation in asymptomatic carriers (ACs) HTLV-1 infected patients, shedding light on early molecular events and T-cell activation following HTLV-1 infection.
MATERIAL AND METHODS
The study involved 40 participants, including 20 ACs and 20 healthy subjects. Blood samples were collected, ELISA assessment for screening and confirmation with PCR for Trans-activating transcriptional regulatory protein (Tax) and HTLV-1 basic leucine zipper factor (HBZ) of the HTLV-1 were done. mRNA expressions of C-terminal Src kinase (CSK), Glycogen Synthase Kinase-3 Beta (GSK3β), Mitogen-Activated Protein Kinase 14 (MAP3K14 or NIK), Phospholipase C Gamma-1 (PLCG1), Protein Tyrosine Phosphatase non-Receptor Type 6 (PTPN6) and Mitogen-Activated Protein Kinase Kinase Kinase-7 (SLP-76) and Mitogen-Activated Protein Kinase14 (MAP3K7 or TAK1) were assayed using RT-qPCR. Statistical analyses were performed using PRISM and SPSS software.
RESULTS
While there were no significant upregulation in CSK and PTPN6 in ACs compared to healthy individuals, expression levels of GSK3β, MAP3K14, PLCG1, SLP-76, and TAK1 were significantly higher in ACs compared to healthy subjects which directly contributes to T-cell activation in the HTLV-1 ACs.
CONCLUSION
HTLV-1 infection induces differential mRNA expressions in key proteins associated with T-cell activation. mRNAs related to T-cell activation showed significant upregulation compared to PTPN6 and CSK which contributed to T-cell regulation. Understanding these early molecular events in ACs may provide potential markers for disease progression and identify therapeutic targets for controlling viral replication and mitigating associated diseases. The study contributes novel insights to the limited literature on T-cell activation and HTLV-1 pathogenesis.

Paraparesis following cardiac surgery is a manifestation of spinal cord injury (SCI). It can occur in any aortic surgery from the aneurysm to the coarctation of the aorta (CoA) where the cross-clamp of the aorta is applied. Though the incidence of paraplegia is low, its occurrence affects the morbidity and mortality of the patient. There are only sporadic case reports on the development of paraplegia following recurrent and technically challenging repair of CoA. However, the spontaneous development of paraplegia has also been reported in cases of unoperated CoA. The present report describes the case of delayed SCI in which paraparesis developed 5 days post a coarctation repair. The risk factors and strategies to protect the spinal cord during aortic surgeries are emphasized.

Glioblastoma, a primary brain tumor known for its adverse prognosis and aggressive nature, presents a significant challenge when occurring in the spinal cord. We report a case of a 20-year-old female with no prior medical history who developed progressive paraparesis and urinary retention, symptoms indicative of an intramedullary glioblastoma in the spinal cord. This case study delves into the clinical presentation, diagnostic process, and therapeutic interventions, highlighting the complexities encountered during the patient's treatment course. Despite the typically poor prognosis associated with glioblastoma, with an average survival rate of approximately 15 months post-diagnosis, our patient's initial response to adjuvant chemotherapy and radiotherapy extended her survival to 34 months. However, tumor recurrence ultimately led to a decision against aggressive treatment, reflecting the challenges in managing this devastating condition. This case emphasizes the importance of a multidisciplinary approach in the care of spinal glioblastoma patients, ranging from neurosurgery, anesthesiology and intensive care, radiology, oncology, anatomic pathology and nuclear medicine, underscoring the complexity of the disease, while highlighting the urgent need for ongoing research and innovation in neuro-oncology to improve treatment outcomes. The use of modern treatment techniques, including the potential role of nanomaterials for drug delivery, suggests avenues for future research. This case report contributes to the scarce literature on spinal glioblastoma, advocating for detailed documentation of cases to enhance understanding and treatment strategies for this formidable disease.
