RESUMEN
Recently, cone-beam computed tomography (CBCT)-guided surgeries have been developed for bone and soft tissue tumors. The present study aimed to evaluate the efficacy of CBCT-guided curettage for osteoid osteoma. Our study population included 13 patients who underwent primary curettage for osteoid osteoma using intraoperative CBCT in a hybrid operating room between April 2019 and November 2022. We collected the following data: sex, age, follow-up period, symptom onset to time of surgery, tumor size and location, length of skin incision, operating time, radiation dose, recurrence, postoperative complications, and visual analog scale for pain during the last follow-up. There were 10 male and 3 female patients, and the mean age was 25.0 years (range, 9-49 years). The mean follow-up period was 10.6 months (range, 0.4-24.0 months). The locations of the tumors were the proximal femur in 6 patients, the acetabular region in 2 patients, and the ilium, tibial shaft, calcaneus, cuboid, and talus in 1 patient each. The mean time of symptoms onset to surgery was 18.7 months (range, 2.3-69.9 months). The mean maximum diameter of the tumor was 5.9 mm (range, 3.5-10.0 mm). The mean length of the skin incision was 2.2 cm (range, 1.5-3.5 cm). The mean operating time was 96.9 minutes (range, 64-157 minutes). The mean dose of radiation was 193.2 mGy (range, 16.3-484.0 mGy). No recurrences, postoperative complications, and reoperation were observed in this study. All the patients reported 0 mm on the visual analogue scale for pain on the last follow-up. CBCT-guided curettage for osteoid osteoma was minimally invasive and reliable. This procedure can be effective for the treatment of lesions found in deep locations such as the pelvic bone and proximal femur or an invisible lesion that cannot be detected by regular fluoroscopy.

BACKGROUND This retrospective study aims to compare the efficacy of computed tomography-guided percutaneous excision and radiofrequency ablation in the treatment of osteoid osteoma. MATERIAL AND METHODS We evaluated 40 patients with osteoid osteoma who underwent either percutaneous excision or radiofrequency ablation between 2012 and 2015. The cohort consisted of 10 female and 30 male patients, with a mean age of 15.1 years (range: 4-27 years) and a mean follow-up time of 19.02 months (range: 11-39 months). Percutaneous excision was performed in 20 patients, while radiofrequency ablation was performed in the remaining 20 patients. RESULTS The success rates of percutaneous excision and radiofrequency ablation were comparable, with unsuccessful outcomes observed in 10% and 5% of patients, respectively. The reasons for failure in the percutaneous excision group were attributed to a marking error and incomplete excision of the wide-based nidus. Complications were limited to pathological fracture (n=1) and deep infection (n=1) in the percutaneous excision group, while no complications were encountered in the radiofrequency ablation group. CONCLUSIONS Both percutaneous excision and radiofrequency ablation demonstrate high success rates in treating osteoid osteoma. However, radiofrequency ablation offers the advantage of a quicker return to daily activities without the need for activity restrictions or splints. While being a more cost-effective option, percutaneous excision should be considered cautiously to minimize potential complications.

Osteoid osteomas typically arise in the long bones of extremities. Patients often report pain relieved by NSAIDS, and radiographic findings are often sufficient for diagnosis. However, when involving the hands/feet, these lesions may go unrecognized or misdiagnosed radiographically due to their small size and prominent reactive changes. The clinicopathologic features of this entity involving the hands and feet are not well-described. Our institutional and consultation archives were searched for all cases of pathologically confirmed osteoid osteomas arising in the hands and feet. Clinical data was obtained and recorded. Seventy-one cases (45 males and 26 females, 7 to 64 years; median 23 years) arose in the hands and feet, representing 12% of institutional and 23% of consultation cases. The clinical impression often included neoplastic and inflammatory etiologies. Radiology studies demonstrated a small lytic lesion in all cases (33/33), the majority of which had a tiny focus of central calcification (26/33). Nearly, all cases demonstrated cortical thickening and/or sclerosis and perilesional edema which almost always had an extent two times greater than the size of the nidus. Histologic examination showed circumscribed osteoblastic lesions with formation of variably mineralized woven bone with single layer of osteoblastic rimming. The most common growth pattern of bone was trabecular (n = 34, 48%) followed by combined trabecular and sheet-like (n = 26, 37%) with only 11 (15%) cases presenting with pure sheet-like growth pattern. The majority (n = 57, 80%) showed intra-trabecular vascular stroma. No case showed significant cytology atypia. Follow up was available for 48 cases (1-432 months), and 4 cases recurred. Osteoid osteomas involving the hands and feet follow a similar age and sex distribution as their non-acral counterparts. These lesions often present with a broad differential diagnosis and may initially be confused with chronic osteomyelitis or a reactive process. While the majority of cases have classic morphologic features on histologic exam, a small subset consists solely of sheet-like sclerotic bone. Awareness that this entity may present in the hands and feet will help pathologists, radiologists, and clinicians accurately diagnose these tumors.

IMPORTANCE: Osteoid osteomas are benign bony overgrowths that can occur in any region of the body. However, they have a predilection to occur in the craniofacial region. Because of the rarity of this entity, there is a lack of literature detailing the management and prognosis of craniofacial osteoid osteomas. OBSERVATIONS: Craniofacial osteomas have a predilection to involve the paranasal sinuses, but can also be found within the jaw, skull base, and facial bones. Because of their slow-growing nature, craniofacial osteomas are often incidentally discovered on routine imaging or after they compress nearby structures or distort nearby anatomy. Osteoid osteomas of the face can be treated with resection via various approaches. Recent advancements describe minimally invasive endoscopic techniques and adjuvant therapy with radiofrequency ablation guided by cone biopsy computed tomography. Osteoid osteomas have an excellent prognosis with complete resection. They demonstrate a low incidence of recurrence when compared with other osteoblastic lesions of the craniofacial structures. CONCLUSIONS AND RELEVANCE: Craniofacial osteoid osteomas remain a developing topic within the field of craniofacial surgery. Their removal may be trending toward minimally invasive techniques. However, all treatment modalities appear to result in improved cosmetic outcomes and low recurrence rates.

Congenital/neonatal bone neoplasms are extremely rare. We present the case of a patient with a neonatal bone tumor of the fibula that had osteoblastic differentiation and a novel PTBP1::FOSB fusion. FOSB fusions are described in several different tumor types, including osteoid osteoma and osteoblastoma; however, these tumors typically present in the second or third decade of life, with case reports as young as 4 months of age. Our case expands the spectrum of congenital/neonatal bone lesions. The initial radiologic, histologic, and molecular findings supported the decision for close clinical follow-up rather than more aggressive intervention. Since the time of diagnosis, this tumor has undergone radiologic regression without treatment.

OBJECTIVE: This project evaluates a cranial lesion from a Hellenistic-era individual excavated by the Mugla Archaeological Museum in Gülagzi, Turkey. MATERIALS: An osseous tumor measuring 3.02 × 3.54 × 2.98 cm originating from the occipital bone of a probable young adult male. METHODS: The tumor was examined using gross morphological inspection, plain radiography (x-ray), and computed tomography (CT) imaging to identify potential differential diagnoses for the osseous cranial tumor. RESULTS: The lesion in question displays features highly consistent with both osteoid osteoma and osteoblastoma. The tumor had a non-sclerotic, sharply demarcated border, a radiolucent nidus measuring less than 2 centimeters in diameter, and homogeneous sclerotic bone surrounding the nidus. CONCLUSIONS: Differential diagnosis determined the osseous tumor to be a benign neoplasm, and in this case the features of the tumor are highly consistent with a diagnosis of either osteoblastoma or osteoid osteoma. SIGNIFICANCE: The identification of novel neoplastic cases in paleopathology represents an important contribution to ongoing discussions regarding the temporality and regional variability of neoplastic conditions in the past. Additionally, a rigorous diagnostic study augmented by x-ray, CT scans, and 3D modeling provides data that can be utilized in future paleopathological studies. LIMITATIONS: Diagnostic interpretation would be aided by histological examination of the tumor, which was impossible in this case. Histological examination would provide a definitive diagnosis. SUGGESTIONS FOR FURTHER RESEARCH: Given the high incidence of benign tumors in the clinical literature but a paucity of reports in the paleopathological record, further research is indicated to better understand the implications of benign neoplasms in antiquity.

CASE: A 22-year-old man presented with long-standing, progressive neck pain of unknown etiology. Investigation revealed a cervical spine osteoid osteoma affecting the right C4-5 facet joint. He underwent minimally invasive en bloc resection with O-arm-assisted 3-dimensional navigation without introducing iatrogenic spinal instability. Symptoms resolved after surgery, without recurrence or instability at the 2-year follow-up. CONCLUSION: Cervical spine osteoid osteoma is a tumor that presents diagnostic and therapeutic challenges. Achieving precise, complete resection of the tumor with a minimally invasive approach while avoiding spinal instrumentation and arthrodesis is paramount to excellent surgical outcomes.

OBJECTIVE: To observe the necessity and usefulness of follow-up Magnetic Resonance Imaging (MRI) and Computed Tomography Imaging (CTI) after RFA of osteoid osteoma. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Department of Radiology, Sisli Etfal Training and Research Hospital, Istanbul, Turkey, between May 2015 and January 2020. METHODOLOGY: Patients, who underwent CT-guided RFA for osteoid osteoma treatment, were followed-up both clinically and radiologically. MRI was recommended between the third and sixth months and CTI at 12th month or later for follow-up. All the pre and post-treatment radiological images were evaluated retrospectively. Radiological recovery was noted in three categories as complete/almost-complete, partial, and minimal-no recovery according to the healing of pre-treatment radiological findings. RESULTS: One-hundred and thirty-one patients with at least one follow-up CT or MRI were included. All had technically and clinically successful RFA treatments. Of 131 patients, 64.1% had CTI and 82.4% had MRI follow-up. In follow-up images, complete/almost-complete-recovery was observed in 70.2%, partial recovery in 26.7%, and minimal recovery in 3.1% of the cases. Re-ablation therapies were applied in 2 cases in this study due to pain recurrence after three months of successful treatments. CONCLUSION: Radiological follow-up is beneficial for the evaluation of outcome after RFA of osteoid-osteoma. At least one follow-up MRI may be helpful for the assessment of healing or recurrence. Follow-up CTI may not be needed unless planning a re-ablation. KEY WORDS: Osteoma osteoid, Radiofrequency ablation, Tomography, Magnetic resonance imaging.

Osteoid osteoma is one of the commonest benign bone tumour of adolescence. Diagnosis is based upon the typical clinical features, site of occurrence and imaging findings. Occurrence of this lesion in an atypical site is associated with delay in diagnosis and challenges in management. We present a rare case of osteoid osteoma in scaphoid in a 14-year-old girl. Comprehensive work-up using radiograph, computerized tomography (CT), magnetic resonance imaging and Tc99-multidetector methylene diphosphonate (MDP) bone scan was used to make the correct diagnosis over other conditions with similar presentation like de Quervain tenosynovitis, intersection syndrome and inflammatory arthropathies. We also describe the treatment using CT-guided percutaneous radiofrequency ablation of this lesion and a brief literature review regarding the incidence of this lesion and treatment options available. Level of Evidence: Level V (Therapeutic).

Excision of acetabular osteoid osteoma is technically difficult. We report osteoid osteoma of the quadrilateral plate in a 9-year-old girl who presented to us with persistent nocturnal pain, limp and restricted hip joint movement. The child was investigated with CT scan, MRI and triple-phase bone scan. The 0.7 cm nidus was located in the central portion of the cancellous bone in the quadrilateral plate, 1.94 cm inferior to the triradiate cartilage. The child was operated on through the safe surgical dislocation of the left hip. The location of the lesion was gauged from the preoperative CT scan measurement data and intraoperative fluoroscopic aid. The nidus with a sclerotic rim was burred down completely. Postoperative X-ray and CT scan revealed complete excision of the tumour, and the patient was pain-free. At 18 months follow-up, the patient is completely asymptomatic and walking normally.

BACKGROUND: Osteoid osteomas of the foot are rare, with a varying and atypical clinical as well as radiological presentation impeding early diagnosis and treatment. The aim of the present multicentre study was to 1) analyze epidemiological, clinical and radiological findings of patients with foot osteoid osteomas and to 2) deduce a diagnostic algorithm based on the findings. METHODS: A total of 37 patients (25 males, 67.6%, mean age 23.9 years, range 8-57 years) with osteoid osteomas of the foot were retrospectively included, treated between 2000 and 2014â¯at 6 participating tertiary tumor centres. Radiographic images were analyzed, as were patients' minor and major complaints, pain relief and recurrence. RESULTS: Most osteoid osteomas were located in the midfoot (nâ¯= 16) and hindfoot (nâ¯= 14). Painful lesions were present in all but one patient (97.3%). Symptom duration was similar for hindfoot and midfoot/forefoot (pâ¯= 0.331). Cortical lesions required fewer xrays for diagnosis than lesions at other sites (pâ¯= 0.026). A typical nidus could be detected in only 23/37 of xrays (62.2%), compared to 25/29 CT scans (86.2%) and 11/22 MRIs (50%). Aspirin test was positive in 18/20 patients (90%), 31 patients (83.8%) underwent open surgery. Pain relief was achieved in 34/36 patients (outcome unknown in one), whilst pain persisted in two patients with later confirmed recurrence. CONCLUSIONS: As previously reported, CT scans seem to be superior to MRIs towards detection of the typical nidus in foot osteoid osteomas. In patients with unclear pain of the foot and inconclusive xrays, osteoid osteoma should be considered as differential diagnosis.

OBJECTIVE: To report a single center's experience evaluating the efficacy and safety of computed tomography-guided radiofrequency ablation for the treatment of osteoid osteoma in children. MATERIALS AND METHODS: Institutional database research identified 33 symptomatic patients (≤ 18 years of age; male/female ratio: 21/12, mean age 13.09 ± 3.66) with osteoid osteoma who were treated by CT-guided RFA. Technical and clinical success as well as complication rates were recorded. The duration of the procedure, the number of computed tomography scans and the results of the biopsy were assessed. Pain, prior, the following morning and 1 week, 1/6/12 months after the procedure were compared by means of a numeric visual scale (NVS) questionnaire. RESULTS: Mean lesion size was 8.28 ± 4.24 mm. Mean follow-up was 23.33 ± 17.61 months (range 12-62). Mean pain score prior to radiofrequency ablation was 9.06 ± 0.80 NVS units. On week 1 and 1/6/12 months, all patients were pain-free reporting 0 NVS units (p < 0.05). The mean procedure time was 54 min (range 51-59) and a mean of 7 CT scans were performed during the ablation session. RF electrode was successfully placed in the center of the nidus in all cases. In our study, none of our patient experienced recurrence of the pain, nor complications. CONCLUSION: The present study demonstrates that percutaneous CT-guided radiofrequency ablation constitutes a safe and effective technique for osteoid osteoma treatment in children.

Spindle cell squamous cell carcinoma of the larynx is a rare, aggressive variant of squamous cell carcinoma. It comprises 0.6-1.5% of all laryngeal cancers. Heterologous mesenchymal differentiation as bone, cartilage, and muscle is uncommon, especially malignant osteoid differentiation, as a handful of cases reported in the literature. We present the case of a 66-year-old male active smoker who presented with dysphonia and acute stridor. On examination, a 2.0 cm pedunculated, broad-base, glottic mass involving the left true vocal cord and ventricle was noted, with extension to the anterior commissure causing a narrowing of the airway. The patient underwent localized left vocal cordectomy. The histopathologic and immunohistochemical findings were consistent with spindle cell carcinoma with malignant osteoid differentiation. The patient is alive, status-post adjuvant five cycles of cisplatin therapy, with no recurrence at 18 months of follow-up. We discuss a literature review of this rare entity with either malignant osteoid or osteocartilaginous differentiation.

BACKGROUND Osteoma is a benign bone tumor that typically arises in facial bones and less frequently in the long bones. It rarely occurs in the appendiceal skeleton. Pathologic findings are similar to those for parosteal osteosarcoma, periostitis ossificans, and osteoid osteoma. Diagnosing osteoma at an unusual site is always problematic. Here, we present a case of costal osteoma that was found incidentally on screening and produced mild symptoms in the patient. CASE REPORT A 53-year-old man was examined because of a rib mass in the eighth rib on his left side, which had been present for 2 years. A computed tomography scan revealed that the intensely dense mass arose from the external surface of the eighth rib. Microscopic examination showed that the lesion consisted of mature lamellar bone with several Haversian systems, typical of an osteoma. No atypical spindle cells or necrosis were identified. The diagnosis was osteoma. CONCLUSIONS Because the anatomy of the ribs poses a challenge when performing needle biopsy, diagnosing bony lesions solely based on that technique is difficult. The diagnosis of costal osteoma should be made carefully, based on clinical, radiological, and pathological findings. To the best of our knowledge, ours is the first case report about a costal osteoma. It is useful for chest surgeons, pathologists, and radiologists as an example of a rare presentation of this tumor.

Osteoid osteoma is a benign osteoblastic tumor, quite uncommon in the spine. We report a case of an osteoid osteoma involving the atlas in a 6-year-old boy, who presented with suboccipital pain and torticollis. Initial radiological findings were ambiguous as magnetic resonance imaging showed mainly edema of upper cervical soft tissues. The subsequent computed tomography depicted a lesion of left lamina of C1. As conservative treatment failed, the lesion was surgically resected and the patient became pain free. To our knowledge, this is the first case of osteoid osteoma involving the atlas associated with abnormal soft tissue reaction reported in literature.

A 22-year-old man is referred to the orthopaedic surgeon. He has pain, mostly at night, in his proximal right tibia that greatly reduces with NSAIDs. The CT scan shows a focal lucent zone, called a nidus, in the tibia cortex, surrounded by reactive, sclerotic bone. This is typical for an osteoid osteoma, a benign bone tumour.

Benign and malign tumors can affect the temporomandibular joint (TMJ) as any other articulation. Nevertheless, TMJ tumors are rare and mostly benign. Their clinical expression is varied including symptomatology similar to TMJ dysfunctional disorders, otologic or neurologic pathologies. In some cases, they remain totally asymptomatic. Hence, diagnosis is difficult since the symptomatology can be misleading with TMJ dysfunctional disorders or otologic disorders wrongly diagnosed. There is thus frequently a long delay between symptoms onset and diagnosis. The great variety of TMJ lesions explains the wide range of possible treatment modalities, mostly based on surgery. We provide here a review of the lesions originating from the TMJ. Tumoral or cystic mandibular lesion affecting the TMJ through local extension will not be discussed. Osteoma, osteoid osteoma, osteoblastoma, chondroma, osteochondroma, chondroblastoma, tenosynovial giant cell tumors, giant cell lesions, non-ossifying fibroma, hemangioma, lipoma or Langerhans cell histiocytosis are all possible diagnosis among the benign tumors found in the TMJ. Pseudotumors include synovial chondromatosis and aneurysmal bone cyst. Finally, malign tumors of the TMJ include mainly sarcomas (osteosarcoma, chondrosarcoma, synovial sarcoma, Ewing sarcoma, and fibrosarcoma), but also multiple myeloma and secondary metastases. We will review the clinical, radiological and histological aspects of each of these lesions. The treatment and the recurrence risk will also be discussed.

Osteoid osteomas are painful benign osteoblastic tumors that usually affect the metaphysis or diaphysis of long bones. Hands are rarely involved. Identification of recurrent lesion by anatomical imaging modalities is a challenge especially in postoperative setting. Diagnosis of osteoid osteoma is based on typical clinical signs, radiographs, bone scintigraphy, thin-slice computed tomography, or magnetic resonance imaging. Atypical locations, multicentricity of nidus, or incomplete excision of the nidus result in a high rate of recurrence. Here we present a case of recurrent osteoid osteoma at an unusual site in left index finger and was operated under gamma probe guidance.
