Physicians Identify Rare Splenic Polyangiomatosis Case

Would you choose regular monitoring over surgery if a doctor found a stable, benign condition?

On May 10, 2026, a case study published in the journal Cureus detailed the diagnosis of a 46-year-old woman with splenic polyangiomatosis. The condition was identified after imaging revealed over 100 nodules within her spleen.

Why it matters

The case highlights the importance of clinical judgment and serial imaging in distinguishing rare benign splenic conditions from potential malignancies. Because the patient remained asymptomatic, medical teams opted for monitoring over immediate surgical intervention.

Imaging confirmed over 100 nodules measuring up to 3 centimeters in diameter, which replaced approximately 80% of the patient's spleen tissue. The spleen reached a length of 17 centimeters by February 2023, up from 15.6 centimeters in late 2021.

The players

Cureus

This is a peer-reviewed, open-access medical journal that publishes original research, review articles, and clinical case reports across all medical specialties.

The details

Doctors ruled out infectious causes such as HIV, hepatitis, and H. pylori before reaching the diagnosis through imaging and clinical evaluation rather than biopsy. The patient has been advised to avoid high-impact and contact activities to prevent potential splenic injury.

Timeline

  1. January 2021: Initial ultrasound identified several simple spleen cysts.

  2. September 2021: A CT scan revealed countless lesions throughout the organ.

  3. December 2021: An MRI recorded the spleen measuring 15.6 centimeters.

  4. February 2023: An MRI confirmed more than 100 nodules occupying 80% of the spleen.

  5. May 10, 2026: The case study was formally published in the journal Cureus.

The Big Picture

This case study updates the application of diagnostic imaging protocols for splenic lesions by demonstrating how serial scans allow clinicians to avoid invasive biopsy procedures in stable, asymptomatic patients. It reinforces the efficacy of non-surgical monitoring for rare splenic manifestations.

For individuals with incidentally discovered splenic nodules, this case underscores the potential to manage conditions without surgery if the patient remains symptom-free and lesions stay stable. It highlights the importance of regular monitoring as a viable clinical pathway.

The takeaway

This case demonstrates that asymptomatic findings of extensive splenic nodules do not always necessitate aggressive surgical intervention. Regular imaging remains the gold standard for tracking stability in cases where biopsy is deemed unnecessary.

What happens next

The patient is scheduled to consult with a general surgeon to discuss the possibility of an elective spleen removal.
