ABSTRACT
We report a rare case of primitive neuroectodermal tumour (PNET) of the prostate occurring in a 26-year-old man with a mass replacing the prostate gland in the absence of any lesion involving the bone and soft tissues. To our knowledge, there is no radiological literature that has described the imaging findings in a case of PNET of the prostate. Imaging findings in cases of PNET of the kidney are described in the literature. On ultrasound, the mass appeared multilobulated and multinodular with intratumoural heterogeneity. No brightly reflective echoes with posterior acoustic shadowing to suggest calcification were noted. MRI revealed a heterogeneous lobulated mass with irregular septae within. The mass showed low signal intensity on T(1) weighted images and appeared heterogeneous on T(2) weighted images. Haemorrhage and necrosis were also seen in the tumour.
