Unusual presentations of hypernephroma.

Area of Science:

• Urology
• Nephrology
• Oncology

Background:

• Renal adenocarcinoma, also known as hypernephroma, can present with varied clinical and imaging findings.
• Early and accurate diagnosis is crucial for effective patient management.

Observation:

• Case 1: A hypernephroma was incidentally discovered during an intravenous pyelogram (IVP) performed for ureteral colic, revealing a distorted renal collecting system and contrast extravasation.
• Case 2: This report details a spontaneous subcapsular renal hemorrhage associated with an underlying hypernephroma.

Findings:

• The varied presentations highlight the importance of considering renal adenocarcinoma in the differential diagnosis of diverse renal pathologies.
• Imaging findings, such as collecting system distortion and spontaneous hemorrhage, can be indicative of renal masses.

Implications:

• These cases underscore the need for thorough diagnostic evaluation in patients with unexplained renal symptoms or findings.
• Recognizing these diverse presentations aids clinicians in timely diagnosis and treatment of renal adenocarcinoma.
