Spontaneous rupture of renal angiomyolipoma presenting with shock; a case report from Tanzania.

introduction and importanceRenal angiomyolipoma (AML) are benign tumors, often incidentally diagnosed with rupture being the commonest complication and cause of mortality. These tumors are rare with a higher prevalence among patients with tuberous sclerosis and female predominance. Management is dependent on tumor size and whether or not the tumor has ruptured. CASE PRESENTATION: 32-year-old female presenting with sudden right flank pain with shock without history of prior trauma or surgeries. Underwent imaging revealing a suspected ruptured AML thus underwent emergent nephrectomy with admission to intensive care. CLINICAL DISCUSSION: Wunderlich syndrome manifests as the Lenk triad, which includes acute flank pain, flank mass, and hypovolemic shock with signs of internal bleeding such as hematuria. It is a rare manifestation signifying spontaneous renal hemorrhage. Due to the instability of the patient had to undergo emergency laparotomy and nephrectomy.

conclusionRenal AML occur as a rare benign phenomenon which when ruptured are associated with high mortality rate if not treated promptly in a setting with specialized treatment and intensive unit care. We hope that through our experience patients presenting with Lenk's triad are identified early for adequate intervention.
