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.
