Iliopsoas myositis mimicking appendicitis: MRI diagnosis.

Myositis of the truncal muscles can closely mimic acute appendicitis. Myositis is the early stage of muscular infection. It is characterized by diffuse muscular pain and swelling without a distinct mass.

Computerized tomographic appearance of hernias of the bladder.
