Bladder schwannomas, rare nerve sheath tumors, are typically linked to Neurofibromatosis type 1 (NF1). This report details a rare case without NF1, highlighting computed tomography imaging findings.

Area of Science:

Urologic Oncology
Radiology
Pathology

Background:

Schwannomas are nerve sheath tumors, rarely originating in the bladder.
Most bladder schwannomas occur in patients with Neurofibromatosis type 1 (NF1).
Sporadic cases are infrequently reported in urologic and pathology literature.

Observation:

This report presents a rare case of bladder schwannoma in a patient without NF1.
Computed tomography (CT) imaging was utilized for diagnosis and description.
This represents the fifth reported case of sporadic bladder schwannoma globally.

Findings:

The study provides detailed radiology-specific descriptions of the bladder schwannoma on CT.
It highlights the imaging characteristics that aid in differentiating schwannoma from other bladder pathologies.

Keywords:

Bladder mass bladder schwannoma neurofibromatosis schwannoma

The case underscores the importance of considering schwannoma in the differential diagnosis of bladder tumors, even in the absence of NF1.

Implications:

This case expands the understanding of bladder schwannoma presentation and diagnosis.
It emphasizes the value of advanced imaging techniques like CT in diagnosing rare tumors.
The findings contribute to the limited radiologic literature on bladder schwannomas, particularly sporadic cases.
