Osteoid osteoma of the acetabulum: diagnosis and medical treatment.

We describe the medical management of an acetabular osteoid osteoma in an 11-year-old girl. There was a 2-year delay until proper diagnosis of the patient's pathology was made. Accurate localization of the nidus in the subchondral bone, involving the cartilage, is difficult on the basis of plain radiographs.

The rare sprengel deformity: our experience with three cases.

Sprengel shoulder is a rare congenital deformity of one or both scapulae that is usually detected at birth. It occurs due to failure of the scapula to descend during intrauterine development and its cause is still unknown. Although the deformity appears randomly most of the time, familial cases have been reported.

Splenic-gonadal fusion in a 6-year-old boy, confirmed by Tc-99m sulfur colloid scanning.

Splenic-gonadal fusion is a rare congenital anomaly, in which splenic tissue is connected to the gonad. It is almost always on the left side, is difficult to be recognized, and unfortunately the final diagnosis is confirmed after an unnecessary orchiectomy in one-third of the cases. We report a case of splenic-gonadal fusion in a 6-year-old boy, referred for a palpable mass at the left testicle.
