Rupture of ectopic pelvic dysplastic kidney after blunt abdominal trauma presenting as left lower quadrant pain.

Background: Ectopic pelvic dysplastic kidney is very rare. To our knowledge, there is no case report in the literature that discusses the diagnosis and management of ectopic pelvic dysplastic kidney in trauma.

Objective: To report an unusual organ injury after abdominal blunt trauma.

Methods: A 23-year-old man presented to the Emergency Department with complaints of left lower quadrant pain after blunt abdominal trauma. Rupture of an ectopic pelvic dysplastic kidney was suspected from ultrasonography and then confirmed by a computed tomography scan. The patient was managed successfully with conservative therapy.

Conclusions: The focused assessment with sonography for trauma examination is beneficial to hemodynamically stable blunt abdominal trauma patients because unusual organ injuries can be detected early.
