Osteoid osteoma is one of the osteoblastic benign bone tumors, which occurs frequently at the cortex of long bones, usually in the diaphysis or metadiaphysis. Although the tumor location in the bone varies, epiphyseal intramedullary osteoid osteoma has been rarely reported. Herein, we report a 14-year-old male patient with epiphyseal intramedullary...

Introduction:
Osteoid osteoma is a benign bone tumor. It occurs in epiphyseal and metaphyseal regions of long tubular bones of extremities. Around 10% of osteoid osteomas present in spine. In the spine, 2% of cases involve sacrum. Here, we present an atypical case of osteoid osteoma in the sacrum.

... This disease most commonly affects children and young adults, with 85% occurring between the ages of 5-24 years, with only 3-8% of cases under 5 years of age [1,2]. While 75% of osteoid osteomas are cortical, 20% are intramedullary [3]. In our article, we aimed to present the follow-up and treatment of intramedullary osteoid osteoma in a 12-month-old girl, which is very rare due to her age and location. ...
Osteoid osteoma is a benign bone tumor consisting of an osteoblastic mass called nidus surrounded by a sclerotic bone. This disease most commonly affects children and young adults, but only 3–8% of cases are under the age of 5. In our article, we aimed to present the follow-up and treatment of intramedullary osteoid osteoma in a 12-month-old girl, which is very rare due to her age and location. A 12-month-old girl patient, who had complaints of uncontrollable crying, not gaining weight, and restlessness, especially at night since she was 8 months old consulted after seeing a swelling in the left cruris. When the nidus was seen with the CT images and the diagnosis was clarified, the parents were informed, and surgical preparation was started. A 2 × 1 cm elliptical bone window was opened, and the red-colored tissue thought to be nidus tissue was removed and sent for histopathological examination. The diagnosis of intramedullary osteoid osteoma was confirmed histopathologically. Only 3–5% of osteoid osteomas occur under 5 years of age. Osteoid osteomas, which appear under 1 year of age, are less common. Classical symptoms may not be seen in osteoid osteomas seen in infants and diagnosis may be challenging. Osteoid osteoma should be kept in mind in the diagnosis of these patients who may present with atypical symptoms in this age group.
Osteoid osteoma is a benign osteoblastic tumour with a predilection for the lower extremity that rarely affects the forearm. It is commonly seen in adolescents and young adults, and is seldom diagnosed in the paediatric age group. We report a boy in his early childhood who presented with a swelling over the distal forearm, which was incidentally noted by the mother 3 months ago. Plain radiographs showed diffuse sclerosis of the dorsal cortex of the distal radius. CT scan showed a central lucent nidus in the intramedullary region and surrounding sclerosis in the radial metaphysis, confirming the diagnosis of osteoid osteoma. The patient was successfully treated by surgical en bloc resection of the nidus and was asymptomatic at 1-year follow-up. Non-specific symptoms at presentation make it a challenge to diagnose osteoid osteoma in children and it needs to be considered in the differential diagnosis when radiographs show lytic lesions in the bone.
