Oh, Kim, and Lee: Imaging Findings of Scrotal Liposarcoma: A Case Report

Abstract

Liposarcoma located in the scrotum is a very rare, and to our knowledge, only a few cases have been described in the radiologic literature. Clinically, scrotal liposarcoma manifests as a painless, slow-growing mass, which can be misdiagnosed as inguinal hernia, scrotal hydrocele or lipoma. Here, we present a case of scrotal liposarcoma. On CT and MRI, it manifested as a predominant fat-containing mass with heterogeneously enhancing soft tissue.

59-year-old male patient with scrotal liposarcoma. A. An ultrasonographic image reveals a heterogeneous, hyperechoic mass in the left hemiscrotum. B. An axial contrast-enhanced CT image shows heterogeneous enhancement of septal and soft tissue components (arrow) in the tumor. C. A coronal contrast-enhanced CT image shows a left scrotal tumor extending along the left spermatic cord (arrow). D. An axial T1-weighted MR image (left) shows a predominantly high-signal intensity mass (arrowheads) with low-signal septa and solid component (arrow) in the left hemiscrotum. An axial T2-weighted MR image (middle) shows a large, predominantly high-signal intensity mass (arrowheads) in the left hemiscrotum. An axial contrast-enhanced T1-weighted, fat-suppressed MR image (right) shows the loss of signal in the fatty portions (arrowhead) and enhancement of the soft-tissue component (arrow) of the mass.

59-year-old male patient with scrotal liposarcoma. E. Gross pathologic specimen shows a 16 × 13 cm, yellow-brown, lobulated tumor with hemorrhagic foci. F. Microscopic assessment of the pathologic specimen reveals marked variation in adipocyte size, compatible with an atypical lipomatous tumor. High-power photomicrograph shows atypical hyperchromatic cells (arrows), another characteristic of an atypical lipomatous tumor (he-matoxylin-eosin staining; original magnification, × 100, × 200).
