Why a man with nerve disease had bladder problems—and what they found
Case report of a seminal vesicle schwannoma involving prostate and bladder: diagnostic pathway and management
Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
A man with a rare nerve disorder had trouble peeing. Scans showed three lumps near his bladder, prostate, and seminal vesicle. Doctors thought they might be cancer, but after removing and testing them, they found they were harmless nerve tumors called schwannomas.
Surprising Findings
A PIRADS 4 prostate lesion turned out to be a benign schwannoma with normal PSA.
PIRADS 4 is considered 'highly suspicious' for cancer, and PSA is the gold-standard blood test. This case breaks both assumptions simultaneously.
Practical Takeaways
If you have urinary symptoms and a PIRADS 4 lesion but normal PSA, ask your doctor: Could this be a rare benign tumor like schwannoma?

Even though this man’s PSA level was normal, an MRI scan showed a spot in his prostate that looked like cancer — but it turned out to be a harmless nerve tumor.
An older man with a known nerve disorder had three unusual growths in his pelvic area that doctors found to be harmless nerve tumors after testing tissue samples.
Doctors removed a growth near the bladder and took tissue samples from the prostate and seminal vesicle using minimally invasive techniques; the patient recovered well and his urinary symptoms didn’t get worse after one year.
The tumors in this man’s pelvic organs looked like classic benign nerve tumors under the microscope — they had two distinct tissue patterns, stained positive for S100, and showed no signs of cancer.
After removing the tumors, the man’s urinary problems didn’t get worse, and a year later, the tumors hadn’t come back.
