Review
Osteoid osteoma of the cuneiform bone is an exceedingly rare and easily missed cause of foot pain. The uncharacteristic and nonspecific radiographs of such intra-articular osteoid osteoma further increase difficulty in making the diagnosis. To date, there has been no description of intra-articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration in any published literatures. We present a case of intra-articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration, who underwent curettage, allograft bone graft, and navicular-cuneiform arthrodesis. The patient presented with radiographic bone union, full motor function recovery and pain-free at the 22-month follow-up. This report adds to the existing literature. Intra-articular osteoid osteoma of the intermediate cuneiform bone causing articular degeneration is an exceedingly rare and easily missed cause of foot pain. It proves a complicated and challenging task to identify intra-articular osteoid osteoma. Clinicians should be particularly careful not to exclude the possibility of arthritis and, thus, vigilant when choosing the surgical option.

BACKGROUND
Osteoid osteoma is a benign osteogenic tumor that occurs mostly in the femoral stem, while osteoid osteoma occurring in the lumbar vertebral body is a relatively rare case. To minimize treatment-related complications, a computer-assisted navigation fully visualized spinal endoscopy was used. Ultimately, the pathology was diagnosed as osteoid osteoma.
CASE PRESENTATION
We report a 19-year-old adult male with low back pain that worsened at night and CT, MRI imaging showed an abnormal signal shadow at the posterior margin of the lumbar vertebral body. Due to the proximity of the lesion to the spinal canal and adjacent to the nerve roots, it was difficult to precisely localize the lesion by purely endoscopic or open procedures, and if necessary, the resection of surrounding tissues had to be expanded, causing unnecessary damage to the surrounding tissues. Therefore, we choose computer-assisted navigation fully visualized spinal endoscopy to perform the treatment.
CONCLUSION
In this case, we report an osteoid osteoma that occurs less frequently in the lumbar vertebral body. Using computer-assisted navigation with fully visualized spinal endoscopy, we successfully resected the osteoid osteoma at the posterior margin of the L3 vertebral body preoperatively by computer-planned path with intraoperative visualization endoscopy, minimizing the damage to spinal stability. Computer-assisted navigation with visualization endoscopy provides a more precise and minimally invasive approach to the treatment of osteoid osteoma of the spine.

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.

OBJECTIVES
The diagnosis of osteoid osteomas (OO) about the hip can be challenging as presenting symptoms can mimic other, more common, periarticular pathologies. Our aims were to identify the most common misdiagnoses and treatments, mean delay in diagnosis, characteristic imaging features and provide tips for avoiding diagnostic imaging pitfalls for patients with OO of the hip.
METHODS
We identified 33 patients (34 tumors) with OO about the hip who were referred for radiofrequency ablation between 1998 and 2020. Imaging studies reviewed included radiographs (n = 29), CT (n = 34), and MRI (n = 26).
RESULTS
The most common initial diagnoses were femoral neck stress fracture (n = 8), femoroacetabular impingement (FAI) (n = 7), and malignant tumor or infection (n = 4). The mean time from symptom onset to diagnosis of OO was 15 months (range, 0.4-84). The mean time from initial incorrect diagnosis to OO diagnosis was 9 months (range, 0-46).
CONCLUSIONS
The diagnosis of OO of the hip is challenging, with up to 70% of cases initially misdiagnosed as a femoral neck stress fracture, FAI, bone tumor, or other joint pathology in our series. Consideration of OO in the differential diagnosis of hip pain in adolescent patients and awareness of the characteristic imaging findings are critical for making an accurate diagnosis.
KEY POINTS
• The diagnosis of osteoid osteoma of the hip can be challenging, as demonstrated by long delays in time to initial diagnosis and high rates of misdiagnoses which can lead to inappropriate interventions. • Familiarity with the spectrum of imaging features of OO, especially on MRI, is imperative given the increase in the utilization of this modality for the evaluation of young patients with hip pain and FAI. • Consideration of OO in the differential diagnosis of hip pain in adolescent patients and awareness of the characteristic imaging findings, including bone marrow edema and the utility of CT, are critical for making a timely and accurate diagnosis.

Osteoid osteoma is a benign bone tumor commonly occurring in the diaphysis and metaphysis of long bones. Only a few cases were reported in the literature about the rare location of epiphyseal osteoid osteoma and all were treated surgically. Herein, we report a rare case of an epiphyseal tibial osteoid osteoma, in a 14-year-old boy, which was initially diagnosed by imaging and confirmed by histopathology. To the best of our knowledge, this is the first case of an epiphyseal osteoid osteoma treated successfully by CT-guided radiofrequency ablation in a pediatric patient with a good outcome and no detrimental effects. The case highlights the rarity of such presentation, the importance of early imaging and diagnosis, and the success of CT-guided radiofrequency ablation in the treatment of epiphyseal osteoid osteoma.

INTRODUCTION
Osteoid osteoma (OO) is a common benign bone tumor. OO is observed most frequently in the long bones, especially in the tibia and femur. When occurring in the bones of the hand, OO can be a diagnostic and therapeutic challenge. The aim of this study was to provide a systematic review of occurrence, symptoms, diagnosis and treatment options regarding OO in hand bones.
MATERIALS AND METHODS
We performed a systematic review of the literature. All studies from the online databases PubMed and SpringerLink, which reported cases of osteoid osteomas in the bones of the hand, were included. By summarizing the literature, we evaluated the localization within the hand as well as diagnostic and therapeutic options.
RESULTS
We included 133 studies reporting 401 cases. OO was mostly common in the phalanges. The diagnosis was mostly made by CT (computed tomography) scan. Most of the OO were treated surgically by open curettage or en bloc resection.
CONCLUSIONS
Osteoid osteomas in the bones of the hand are rare and a delayed diagnosis is common. In cases of pain combined with particular symptoms such as nail hypertrophy and swelling OO should be considered. Of the most used imaging methods, CT scans have the highest sensitivity.

Osteoid osteoma is a benign bone tumor that commonly arises from the metaphyseal and diaphyseal regions of long bones. Pain is often the first symptom, and it can mimic many diseases. Herein, we report a 36-year-old male patient who presented with complaints of lower back pain radiating to the right extremity for a year. In the patient's history, physical therapy, platelet-rich plasma, pregabalin, and duloxetine were used, with the only benefit from indomethacin. An X-ray of the femur was requested, and the diagnosis of osteoid osteoma was confirmed by magnetic resonance imaging. Osteoid osteoma should be kept in mind as a differential diagnosis of persistent pain despite treatment.

Carpal bone tumors must be investigated in clinical cases of chronic wrist pain with no previous trauma. Intraosseous ganglion, enchondroma, osteoid osteoma, and, less commonly, osteoblastoma are potential causes of osteolytic lesions affecting the carpal bones. In most cases, the clinical presentation alone is not enough to differentiate such lesions. Knowledge of certain characteristics, including the radiological and histopathological aspects of each of these tumors, is critical in order to make the differential diagnosis. We present a rare case of osteoblastoma of the capitate bone and review the literature on the subject.
