| ABSTRACT |  | ||||||
: Prostate stromal sarcoma is a rare neoplasm arising from the stromal component of the prostate. The clinical symptoms of prostatic sarcoma and prostatic adenocarcinoma are similar. It differs from more common prostatic adenocarcinoma in terms of age of presentation, biological behaviour, and imaging appearance. Magnetic Resonance Imaging (MRI), including Diffusion-Weighted Imaging (DWI), is the modality of choice for lesion characterisation, assessment of local extent, and surgical planning. We are presenting a case series of four patients presenting with lower urinary tract symptoms, including urinary urgency, frequency, dysuria, and pelvic pain, all of whom had normal serum Prostate-Specific Antigen (PSA) levels. MRI demonstrated a large T2-weighted hyperintense mass with internal cystic changes and marked diffusion restriction on DWI. The lesion appeared predominantly well-defined, with areas of heterogeneity corresponding to cystic or necrotic components. On Apparent Diffusion Coefficient (ADC) maps, these regions showed low signal intensity, consistent with true diffusion restriction, suggestive of high cellularity. | |||||||
