Benign non-cystic scrotal tumors and pseudotumors

Abstract

There is a wide spectrum of benign, non-cystic scrotal lesions that show characteristic histo-morphology and natural history. While sonography is the preferred modality for the diagnosis of both testicular and extratesticular masses, MRI is used as a problem-solving modality when sonographic findings are inconclusive. This article reviews the cross-sectional imaging features of benign, non-cystic, intra- and extratesticular lesions. Definitive diagnosis of benign scrotal lesions may lead to conservative management including testicular preserving surgery.

Contemporary diagnostic work-up of testicular germ cell tumours

“…56,62,63 MRI can be used to identify vascularization disorders, such as spermatic cord torsion or segmental testicular infarction, [64][65][66] and to distinguish between intra testicular cystic lesions and neoplastic growths. 67,68 Neoplasms are plainly identified on MRI.…”

A Case of Fibrous Pseudotumor in the Scrotum: Challenge for Diagnosis and Testicular Preservation

“…[ 14 ]. Although case reports with MRI are limited, some studies have reported a specific appearance with an extratesticular multiple nodular lesion that exhibits intermediate-to-low signal intensity on T1- and T2-weighted images, with little or no gadolinium enhancement [ 20 , 23 ]. Our result showed similar observation and suggested that water imaging might be useful for tumor visualization (Figures 1(f) and 1(g) ).…”

AIUM Practice Guideline for the Performance of Scrotal Ultrasound Examinations

“…Indications for scrotal ultrasound 1 , 2 include but are not limited to the following: Evaluation of scrotal pain, including but not limited to testicular trauma, ischemia/torsion, and infectious or inflammatory scrotal disease 3 – 7 Evaluation of palpable inguinal, intrascrotal, or testicular masses 1 , 2 , 8 , 9 Evaluation of scrotal asymmetry, swelling, or enlargement 1 , 2 , 10 – 12 …”
