Osteoid osteoma in the neck of the Scapula; A misleading case.

Osteoid osteoma is a benign bone tumor that when located on the base of the coracoids process of the scapula is very rare and diagnosis and treatment is often delayed because of its rarity. Almost any bone can be involved, but half of cases involve the femur or tibia. The radiologic features of osteoid osteoma are well known, but these tumors may present with unusual features and be easily misdiagnosed. In this report, we present a case of osteoid osteoma of the neck of the left scapula that took almost 27 months to be diagnosed accurately.
