An Unusual Presentation of Urinary Retention in a Young Male Patient With Neurofibromatosis Type 1.

Acute urinary retention (AUR) in young adults is an uncommon presentation often signalling an underlying pathology, particularly when associated with genetic conditions like neurofibromatosis type 1 (NF1). We report the case of a 25-year-old male with a known family history of NF1, who presented with acute urinary retention and progressive pelvic pain. Physical examination was notable for axillary freckling and café-au-lait spots, consistent with NF1. Imaging revealed a large heterogeneous pelvic mass displacing the bladder and rectum. This case emphasises the importance of considering rare aetiologies for acute urinary retention in young males.
