INFLAMMATORY RENAL PSEUDOTUMOR IN WEGENER'S GRANULOMATOSIS: INITIAL MANIFESTATION OF A CASE

Case Report

Abstract

We report a case of a 37-year-old woman who was treated in the emergency department with low back pain and intermittent cough for 7 days. Computed tomography and magnetic resonance imaging of the abdomen and pelvis revealed an expansive, heterogeneous formation with ill-defined limits, measuring 6.3 x 5.1 cm, in the upper third of the left kidney and a second expansive formation located in the lower pole of the left kidney, measuring 5.1 x 5.9 x 6.4 cm. She then underwent uneventful left videolaparoscopic radical nephrectomy. After the procedure, the patient progressed with prostration, decreased general condition and cough with brownish secretion, in addition to complaining of decreased visual and hearing acuity. She underwent laboratory and imaging tests, revealing bilateral cavitated lung masses that proved to be a case of Wegener's granulomatosis. Treatment with pulse therapy was initiated, but the patient died days later. This is the 11th case described in the scientific literature and serves as a warning to guide the management of this rare clinical condition, especially with regard to the presentation of inflammatory renal pseudotumor.
