ORTEGA HRESCAK, M.C. et al. Quiste gigante de vesícula seminal: presentación atípica de una patología infrecuente. Rev. argent. radiol. [online]. 2015, vol.79, n.2, pp.100-106. ISSN 1852-9992.

The case is presented of a 14 year-old boy with a previous diagnosis of left femur enchondroma. The pelvic and hip magnetic resonance imaging (MRI) unexpectedly revealed a right giant seminal vesicle cyst. He was evaluated by performing abdominal-pelvic computed tomography, with and without intravenous contrast. The pathology of the seminal vesicles (SV) can be classified as congenital and acquired. The first type has low prevalence (cyst and agenesis being the most frequently encountered in daily practice) and often co-exists with ipsilateral abnormalities in the upper urinary tract and genital organs, due to the close relationship of the male reproductive and urinary systems during embryogenesis. The association with bone and vascular anomalies has also been described. Abdominal and trans-rectal ultrasound, followed by abdominal and pelvic MRI, are the most accurate methods for preoperative diagnosis. Vesiculo-de/erentography (traditionally the gold standard test for diagnosis) is only applied in selected cases. The treatment, vesiculectomy, with or without removal of dysplastic or hypoplastic kidney, is restricted to symptomatic patients.
