18F-FDG PET/CT of Alveolar Rhabdomyosarcoma of Prostate in a 17-Year-Old Boy

Abstract

Rhabdomyosarcoma of the prostate is a rare malignancy that usually presents in childhood and adolescence with symptoms of bladder outlet obstruction. Serum prostate-specific antigen is usually normal, and 18F-FDG PET/CT has a crucial role to rule out distant metastases. We present a case of alveolar rhabdomyosarcoma of the prostate in a 17-year-old boy.

18F-FDG PET/CT Imaging of Prostatic Epithelioid Hemangioendothelioma

“…It can occur in any part of the body, and the soft tissues, liver, lung, and bones most commonly involved 1,2 . Epithelioid hemangioendothelioma of prostate is even rarer, and its potential differentials include prostatic adenocarcinoma, 3 prostate carcinosarcoma, 4 metastasis, 5 lymphoma, 6 malignant fibrous histiocytoma, 7 synovial sarcoma, 8 alveolar rhabdomyosarcoma, 9 and extraskeletal Ewing sarcoma 10 . PET/CT imaging has proven to be a valuable tool for diagnosing and staging epithelioid hemangioendothelioma as well as evaluating treatment efficacy 11,12 .…”
