A giant spinal schwannoma mimicking a renal mass
Spinal schwannomas arise from the cells covering the nerves within the spinal canal. In most cases, they remain confined within the intradural extramedullary space, but occasionally they extend into the extradural space resembling abdominal masses.

Published in the journal Radiology Case Reports, the authors present a case of very large spinal schwannoma mimicking a renal mass at ultrasound exam. Using contrast-enhanced computed tomography and magnetic resonance imaging the authors were able to detect and characterize the lesion and consequently assign a preoperative diagnosis later confirmed by the histopathology report.

In this paper, the authors review computed tomography and magnetic resonance imaging features of spinal schwannomas and attempt a summary of possible differential diagnoses.

A 50-year-old man presented to the emergency room with recent onset of abdominal pain radiating to his right back. He denied any other gastrointestinal, urinary, and constitutional symptoms.
