Abstract
In this study, an unusual case of osteoma is presented, whereby a bone marrow osteoma was identified in the tibia. No previous cases of bone marrow osteoma have been reported. In this case, an eight-year-old male presented with discontinuous discomfort in the right distal calf for six months. Radiological examination and computed tomography revealed a radiopaque lesion within the affected bone. A technetium-99m bone scan revealed focally increased uptake in the same region. Together, these observations prior to surgery indicated that the patient may suffer from bone disease. Subsequently, a surgical excision was performed and the biopsy specimen was identified as bone marrow osteoma. Following surgery, the symptoms were eradicated and the prognosis was positive during the 24-month follow-up period. Bone marrow osteoma should be considered when a patient suffers from discontinuous and unexplained limb discomfort.
Highlights
Osteoma is a rare but benign tumor, which is caused by abnormal growth of bone or excessive proliferation of other tissues
Osteoma exhibits continuous growth during childhood rather than exhibiting growth cessation during adulthood. This is the major feature that distinguishes osteoma from other bony exostosis, including tori [1,2,3,4]
Osteoma often occurs in the skull and facial bones, it may occur in the limbs and other body parts
Summary
Osteoma is a rare but benign tumor, which is caused by abnormal growth of bone or excessive proliferation of other tissues. Osteoma exhibits continuous growth during childhood rather than exhibiting growth cessation during adulthood This is the major feature that distinguishes osteoma from other bony exostosis, including tori [1,2,3,4]. A case of a patient with bone marrow osteoma located in tibia who underwent surgical excision of the lesion is presented. Computed tomography (CT) scans of the distal tibia revealed that medullary cavity was narrow and packed with high‐density osteoid tissue (Fig. 2). A technetium‐99m bone scan showed focally increased uptake in the same region (Fig. 3). These observations indicated that the patient may have suffered from bone disease. Histological examination revealed that the excised mass was a bone marrow osteoma. The patient was followed up for 24 months without any recurrence
