Abstract

|
A fibrous pseudotumor is a rare benign fibroproliferative disease of the paratesticular tissues, usually originating from the tunica vaginalis. A 33-year-old man with a painless palpable mass on the right scrotum visited our institution. On ultrasonography (US), multiple well-defined isoechoic nodular lesions with a small amount of vascularity were seen along the tunica vaginalis. Some of the nodules showed posterior shadowing. On magnetic resonance imaging (MRI), the lesions showed dark signal intensity on the T2-weighted image and slightly low signal intensity on the T1-weighted image. The dynamic contrast-enhanced MRI showed a mild and progressive enhancement which was persistent on the delayed phase. After surgical excision, the mass was pathologically confirmed as fibrous pseudotumor. Herein we report a case of fibrous pseudotumor of the tunica vaginalis, which was diagnosed with both US and MRI findings.
