“…These results also support the previous findings of Barei et al (36), who investigated similar items in a small series of patients. Our relatively uniform CT and preprocedural MRI patterns were in agreement with the literature (16,(37)(38)(39)(40)(41)(42), but the follow-up (mean, 3.4±2.2 months) MRI varied considerably.

ORIGINAL ARTICLE PURPOSE We aimed to retrospectively evaluate the computed tomography (CT) and magnetic resonance imaging (MRI) findings of patients with osteoid osteoma treated with CT-guided radiofrequency ablation (RFA) along with the clinical outcome and long-term success. MATERIALS AND METHODSSeventy-three CT-guided RFA procedures were performed in 72 patients. The long-term success was assessed using a questionnaire including several visual analog scale scores. The CT evaluation included pre-and immediate postprocedural imaging of all 72 patients, and MRI was performed in 18 patients with follow-up imaging (mean, 3.4±2.2 months). The evaluation criteria included nidus morphology and a correlation with markers of clinical success. RESULTSThe primary technique effectiveness rate was 71/72 (99%). One relapse was successfully retreated, leading to a secondary technique effectiveness rate of 72/72 (100%). The longterm follow-up (mean, 51.2±31.2 months; range, 3-109 months) revealed a highly significant reduction of all assessed limitation scores (P < 0.001). The CT morphology was typical in all cases and did not change during the short-term follow-up. The follow-up MRI patterns varied considerably, including persistent nidus contrast enhancement in one-third (6/18) and persistent marrow edema in half (9/18) of the patients. None of the investigated MRI and CT patterns correlated with the clinical outcome. CONCLUSIONThe long-term outcome of CT-guided RFA of osteoid osteoma is excellent. There is no correlation of the CT and MRI patterns with the clinical outcome. Thus, the treatment decisions should not be solely based on the imaging findings. Investigators should also be aware of the variety of imaging patterns after RFA.

Osteoid osteoma is a benign bone tumor. A few cases of metacarpal osteoid osteoma have been reported, but the phalanges are the most frequent sites in the hand, followed by the carpal bones. We report a case of an osteoid osteoma of the right first metacarpal bone in a 32-year-old woman. The clinical and radiographic findings along with the pathology results are presented. At the 1 year follow-up there was no evidence of recurrence. Finally, Osteoid osteoma of the metacarpal bones should be considered in the diagnosis of chronic pain in the hand of a young patient, presenting with or without a history of previous injury Copy Right, IJAR, 2017,. All rights reserved. …………………………………………………………………………………………………….... Introduction:-Osteoid osteoma represents 10% of all benign bone tumors with a localization in the wrist and the hand in 6% to 13% of reported cases only [1,2]. The phalanges are the most frequent sites [3], followed by the carpal bone and finally the metacarpals which are the least common sites [4]. We report a cas of osteoid osteoma of the first metacarpal in a young patient and describe the clinical presentation, radiological findings and successful outcome after surgical excision of the lesion Case Report:-A 32 year-old woman, whitout any antecedent of injury, was referred to our hospital last year with history of pain in her first right finger. The pain increased at night and was reduced by non-steroidal anti-inflammatory agents. The physical examination was normal and the radiographs showed an extension of the metaphysis of the right first metacarpal bone (Figure 1a).

“…The typical radiographic and clinical features of osteoid osteoma are not always distinguishable. Intracortical lesions of long bones produce extensive fusiform thickening of the cortex with dense radiopacity, which may obscure the nidus of osteoid osteoma (12). In cases of osteoid osteoma in small bones and the spine, the nidus may not be visible on plain radiographs; therefore, additional imaging studies, including CT, MRI and radionuclide imaging, may be required for the confirmation of diagnosis (13).…”

Radionuclide imaging in the diagnosis of osteoid osteoma

et al. 2015

Abstract. Oseteoid osteoma is a well-known type of benign bone-forming tumor, which has previously been diagnosed using plain radiograph imaging. However, diagnosis of osteoid osteoma may be delayed due to ambiguities on plain radiograph images; despite the increasing use of magnetic resonance imaging (MRI), this type of misdiagnosis is not uncommon. The aim of the present study was to evaluate the effectiveness of radionuclide imaging scans for the diagnosis of osteoid osteoma, as this form of imaging was proposed to be a more sensitive test. The characteristics of 18 cases of osteoid osteoma were analyzed based on diagnostic imaging and the time from initial recognition of symptoms by the patient to diagnosis. Diagnostic modalities included plain radiograph, computed tomography (CT), MRI and radionuclide imaging. Among the 18 patients, 14 patients had unique positive findings in plain radiographs. The mean duration between initial cognition of symptoms to the diagnosis for these patients was 5.2 months (range, 3.8-9.3 months). A total of 4 patients exhibited no radiographic abnormalities in the initial plain radiographs and were diagnosed a mean of 18.5 months (range, 17-20 months) following the onset of symptoms. Overall, radionuclide imaging was performed on 16 patients and all of the cases demonstrated positive findings. In these cases, 28.6% of osteoid osteoma patients with clinical indications revealed no abnormal findings in plain radiographs. Therefore, in situations such as these, radionuclide imaging may be a useful indicator for diagnosis, as these results have demonstrated that it positively identified all cases of osteoid osteoma. In addition, the results of the present study indicated that if the radionuclide imaging was positive, CT scan was a more valuable diagnostic tool, whereas if the radionuclide imaging was negative, MRI should be recommended for the diagnosis of other undiscovered disease entities.
