Review
PURPOSE
The purpose of this study is to develop an accessible step-wise management algorithm for the management of pediatric spinal osteoid osteomas (OOs) based on a systematic review of the published literature regarding the diagnostic evaluation, treatment, and outcomes following surgical resection.
METHODS
A systematic review of the literature was conducted on PubMed to locate English language studies reporting on the management of pediatric spinal OOs. Data extraction of clinical presentation, management strategies and imaging, and treatment outcomes were performed.
RESULTS
Ten studies reporting on 85 patients under the age of 18 years presenting with OOs were identified. Back pain was the most common presenting symptom, and scoliosis was described in 8 out of 10 studies, and radicular pain in 7 out of 10 studies. Diagnostic, intraoperative, and postoperative assessment included radiographs, computed tomography (CT) scans, magnetic resonance imaging (MRI), bone scans, and frozen section. Treatment options varied, including conservative management, open surgical resection with or without intraoperative imaging, and percutaneous image-guided treatment. All included studies described partial or complete resolution of pain in the immediate postoperative period.
CONCLUSIONS
The proposed algorithm provides a suggested framework for management of pediatric spinal OOs based on the available evidence (levels of evidence: 3, 4). This review of the literature indicated that a step-wise approach should be utilized in the management of pediatric spinal OOs.

BACKGROUND
Forehead osteoma is a commonly encountered benign facial bone tumor. Endoscopic excision of benign forehead masses is widely performed. Here, we report a rare case of recurrent forehead osteoma that disseminated after a previous osteoma excision.
CASE SUMMARY
A 54-year-old female patient had previously undergone endoscopic removal of a single forehead osteoma at 30 years of age. However, she had a recurrent osteoma around the same site and underwent another endoscopic resection at 40 years of age. During her first visit to our outpatient clinic, she presented with a cobblestone-like irregular surface on the forehead and a 3D facial bone computed tomography scan revealed a widely ragged surface of the inoculated osteoma on the outer table of the frontal bone. Under general anesthesia, we performed a radical complete excision of the disseminated osteoma through a bicoronal incision using an osteotome, chisel, mallet, and rasping. We hypothesized that the recurrence may have been caused by the inoculation of residual osteoma remnants from the previous procedure. Craniofacial surgeons should be cautious when removing osteoma particles, particularly when using an endoscopic approach.
CONCLUSION
To prevent recurrence, it is essential to conduct additional meticulous burring and a thorough inspection of the surface after copious irrigation.

PURPOSE
To report a case of multiple choroidal neovascularizations (CNVs) secondary to choroidal osteoma injected with a total of 13 anti-vascular endothelial growth factor (VEGF) drugs over a long-term follow up of 6-year period.
METHODS
Case report.
RESULTS
A 29-year-old female presented with a peripapillary choroidal osteoma in her left eye with the best-corrected visual acuity (BCVA) of 20/25. After 2 years of follow-up, two foci of CNV (one was at the infra-nasal of the optic disc, and the other was near the sub-temporal vascular arch), and massive subretinal hemorrhage developed overlying the osteoma, causing decreased BCVA of 20/33. The patient was treated with four consecutive intravitreal injections of conbercept and the two CNVs regressed with BCVA recovered to 20/25. While 17 months later, the third CNV lesion locating at the fovea appeared and nine more injections of aflibercept were given during which repeated recurrence of it occurred. At last follow-up, 6 years from baseline, all the three CNV foci were controlled, with final BCVA of 20/33.
CONCLUSIONS
Multiple CNVs may appear simultaneously at different locations in one osteoma and prompt treatment with intravitreal anti-VEGF may be a good option to control the progression and recurrence of these CNVs. Long-term follow-up and multimodal imaging are vital in the management of CO-associated CNV.

A 15-year-old male patient presented with a 3-week history of inner left thigh pain provoked by activity and experienced occasionally at rest. The patient denied nighttime pain, fever, or chills. Laboratory investigation revealed the following normal values: hemoglobin level of 15.6 g/dL (normal range, 13-16 g/dL), platelet count of 240 × 103/µL (normal range, 140-440 × 103/µL), and total leukocyte count of 7100 cells/µL (normal range, 4500-11 000 cells/µL). The percentage of neutrophils was considered low at 44% (normal range, 54%-62%), and the percentage of eosinophils was slightly high at 3.7% (normal range, 0%-3%). An anteroposterior radiograph of the left hip is shown. Physical therapy was initiated, with no improvement after 2 weeks of therapy. The patient was referred to an orthopedist for further evaluation. At physical examination, the patient endorsed marked left hip pain with hip flexion to 90°, limited internal and external rotation (5° and 15°, respectively), and antalgic gait favoring the left leg. Hip MRI and further serologic analysis were requested for further evaluation. Although the serologic testing was performed at an outside laboratory, the physician reported positive immunoglobulin-G Lyme titers, normal C-reactive protein level, and normal erythrocyte sedimentation rate. Pelvic CT was requested. The patient was prescribed a course of doxycycline (100 mg twice daily for 28 days), with reported resolution of symptoms 2 weeks after initiation of treatment. Three weeks later, the patient presented to our department with recurrent left hip pain, which was similar in severity compared with the initial presentation. A second MRI examination of the left hip was performed 4 months after the initial presentation.

Meta-Analysis
OBJECTIVE
Magnetic resonance-guided focused ultrasound (MRgFUS) is a novel noninvasive interventional technique for osteoid osteoma (OO). The purpose of this study was to evaluate the efficacy and safety of MRgFUS in the treatment of OO through a systematic review and meta-analysis of pain scores and post-treatment adverse events before and after MRgFUS treatment.
MATERIALS AND METHODS
A comprehensive literature search of PubMed, Embase, Web of science, and Cochrane Library databases was conducted to screen the study literature based on inclusion and exclusion criteria to extract and analyze pre- and post-treatment pain score data, success rates (complete pain relief with no recurrence until the last follow-up), recurrence rates, secondary intervention rates, and complications to evaluate the efficacy and/or safety of MRgFUS for OO.
RESULTS
A total of 113 studies published between 2012 and 2022were collected, resulting in a total sample size of 353 patients. The majority of the studies were prospective and had a follow-up period of 4 weeks or more, and overall, the quality of evidence ranged from low to high. Pain scores at 1 week and 1 month after the merger were 0.62 (9.5% CI:0.28-0.96) and 0.37 (9.5% CI:0.07-0.68), respectively. The success rate of the combination was 92.8% (95% CI: 89.8%-95.7%), the incidence of minor complications (thermal injury at the ablation site) was 0.85%, and no major complications were recorded in any of the included literature.
CONCLUSION
MRgFUS is an effective procedure that is able to treat pain for patients with OO with satisfying efficacy and safety.

Background In this study, we aimed to determine the prevalence and radiographic features of incidental head and neck soft tissue calcifications (STCs) on panoramic imagesand assess their clinical significance. Methodology Following well-established training and calibration procedures, 9,553 digital panoramic radiographs (DPRs) taken between January 1, 2021, and January 31, 22, were retrospectively evaluated. Only obvious calcifications and clear differential diagnoses were considered. The presence, type, side (i.e., unilateral or bilateral), number (single or multiple), and the presence of different calcifications in the same individual were recorded. STCs were recorded according to age and gender. Data were analyzed using the chi-square test and Fisher's exact test using SPSS version 18.0 (IBM Corp., Armonk, NY, USA). Results Overall, 35.8% of the DPRs studied showed the presence of STCs, including ossified stylohyoid complex (OSHC) (10.3%), thyroid cartilage (9.8%), tonsillolith (9.2%), atherosclerotic plaques (5.8%), calcified triticeous cartilage (CTC) (5.1%), sialolith (1.9%), as well as intra-articular (1.3%) and other calcifications (0.1-0.8%), i.e., calcified lymph node, antrolith, rhinolith, phlebolith, and osteoma cutis. STCs were found to be more prevalent in middle-aged patients and in females. A significant relationship was identified between the presence of carotid artery calcification and calcified superior horn of thyroid cartilage (CSHTC), as well as between the presence of CSHTC and CTC. Calcifications were detected either bilaterally (n = 2,003) or unilaterally (n = 2,388); however, OSHC mostly showed bilateral calcifications (8.5%). Conclusions Panoramic radiographs of dental patients reveal the frequent occurrence of STCs in the head and neck region with differing radiographic features. Certain calcifications show gender and age differences. Accurate detection of STCs may guide the identification of potential underlying diseases and help initiate referral to the relevant multidisciplinary teams.

Review
Magnetic resonance-guided focused ultrasound (MRgFUS) is a noninvasive, incisionless, radiation-free technology used to ablate tissue deep within the body. This technique has gained increased popularity following FDA approval for treatment of pain related to bone metastases and limited approval for treatment of osteoid osteoma. MRgFUS delivers superior visualization of soft tissue targets in unlimited imaging planes and precision in targeting and delivery of thermal dose which is all provided during real-time monitoring using MR thermometry. This paper provides an overview of the common musculoskeletal applications of MRgFUS along with updates on clinical outcomes and discussion of future applications.

Phosphaturic mesenchymal tumor is a rare tumor characterized by paraneoplastic osteomalacia. The diagnosis is often delayed because of nonspecific symptoms and difficulty to localize the tumor. In this study we report a case of PMT of the left femur detected by Ga-68-DOTATATE PET-CT with radiological features mimicking osteoid osteoma. We report a 31-year-old female patient who presented to our hospital for evaluation due to progressive bone pain and muscle weakness. Her laboratory data showed hypophosphatemia and increased fibroblast growth factor 23 (FGF-23) together with reduced bone mineral density on bone densitometry. The diagnosis of PMT was suspected and the tumor was identified on Ga-68-DOTATATE PET-CT as a focal uptake in a lucent lesion of the left femoral head with a central sclerotic dot mimicking a nidus as seen in osteoid osteoma. The lesion was treated with percutaneous radiofrequency ablation. Laboratory tests and bone densitometry rapidly improved post-treatment. The present case emphasizes the difficulty to diagnose PMT due to its nonspecific biochemical and clinical presentation and the relevance of functional imaging for locating these tumors despite different radiological presentation.

International Journal of Surgery Case... Nov 2023Osteoma is a benign, and usually asymptomatic bone tumor normally found in the skull and facial bones, although it can occasionally occur in the long bones and spine.
INTRODUCTION AND IMPORTANCE
Osteoma is a benign, and usually asymptomatic bone tumor normally found in the skull and facial bones, although it can occasionally occur in the long bones and spine.
CASE PRESENTATION
In this article, we present a 49-year-old male patient who experienced progressive neck pain accompanied by left-sided radicular pain symptoms. Clinical investigation using various imaging techniques confirmed a bone-forming lesion located within the C1 vertebrae region. Treatment involved performing hemilaminectomy of C1 along with resection for complete removal of this extradural bone lesion, ultimately achieving symptom relief. Histopathological examination of the resected specimen leads to the diagnosis of osteoma. Along with reporting this case, we conducted a comprehensive literature review of the previously reported spinal osteoma cases.
CLINICAL DISCUSSION
Histopathological examination confirmed the diagnosis of osteoma. A comprehensive literature review was conducted, revealing 16 previously reported cases of spinal osteoma. Among these, only one case involved the C1 vertebra and presented similar neurological symptoms. The review underscores the rarity of spinal osteomas and the importance of surgical intervention for symptom relief.
CONCLUSION
Spinal osteomas are rare but should be considered in the differential diagnosis of patients presenting with neck pain and radicular symptoms. Surgical removal of the lesion is often necessary for symptom relief, as highlighted by our case and supported by the literature review. This case adds to the limited body of evidence on spinal osteomas and emphasizes the importance of a multidisciplinary approach for optimal patient outcomes.
