Avulsion fracture of the anterior inferior iliac spine mimicking a bone tumor: a case report

ABSTRACT

This is a case of a 17-year-old boy who was admitted to the clinic suffering from right hip-inguinal region pain which began after a soccer match. He had an avulsion fracture in the anterior inferior iliac spine and CT/MR images showed similarities to a bone tumor. These fractures are especially seen in the apophyses which are within the ossification process. The radiological appearance of these fractures during the healing period may be involved with bone tumors. In the control MRI of the patient after one year, the fracture was almost healed completely. Treatment is generally conservative. Good results have been reported with rest, analgesic and anti-inflammatory drugs. Familiarity with radiological findings of these avulsion fractures in this region not only protects the patient from invasive procedures but also avoids the involvement of the practitioner in legal consequences resulting from a misdiagnosis of sarcoma
