Ejaculatory duct cysts are a rare type of prostatic cysts. We report 3 cases of symptomatic ejaculatory duct cysts which have been explored by MR imaging. The MR findings were round or oval masses, medial or paramedial in the prostatic gland above the level of the verumontanum, extending into the prostatic base. They displayed a low signal intensity on T1-weighted images and high signal intensity on T2-weighted images (2 cases) or high signal intensity on both T1- and T2-weighted images (1 case). The diagnosis was confirmed by an ultrasonographically guided transperineal aspiration demonstrating spermatozoa in the cyst fluid.

Soft tissue sarcomas are investigated by magnetic resonance imaging (MRI) both for initial staging and follow-up. We describe the presence of increased signal on T2-weighted images caused by a neurotized muscle flap following reconstructive surgery. This raised concern about possible sarcoma recurrence that was not clinically evident. On post-operative imaging of sarcomas the presence of recurrent tumour is indicated by a mass and high signal intensity on T2-weighted images. However, high signal changes in skeletal muscle on T2-weighted images are not specific. In this case, the free functioning muscle transfer with neurotization of the flap mimicked recurrence on MR scan. High signal intensity on T2-weighted images in muscle is an indication of either a physiological change or a pathological condition and must be taken in context of the clinical picture.
