Summary

Computed Tomography (CT) effectively identifies bleeding renal angiomyolipomas, a rare cause of abdominal hemorrhage. Prompt diagnosis is crucial for guiding surgical intervention in these critical cases.

Area of Science:

  • Radiology
  • Urology
  • Pathology

Background:

  • Renal angiomyolipomas are benign tumors.
  • Hemorrhage from these tumors can lead to acute abdominal conditions.

Purpose of the Study:

  • To report on three cases of abdominal hemorrhage due to bleeding renal angiomyolipomas.
  • To evaluate the role of Computed Tomography (CT) in diagnosing these cases.

Main Methods:

  • Retrospective review of three patients with symptomatic renal angiomyolipomas.
  • Emergency abdominal CT scans were performed.
  • Surgical intervention and histological confirmation were obtained for all patients.

Main Results:

  • CT identified renal lesions with inhomogeneous density and characteristic fat-density areas in all patients.

  • Lesion sizes ranged from 5-9 cm.
  • Two lesions were in the right kidney, one in the left.

    • Conclusions:

    • Renal angiomyolipomas can cause hypovolemic shock.
    • CT is valuable for diagnosing the cause of hemorrhage.
    • Diagnosis is straightforward with typical fat content but can be challenging with atypical presentations.
