Why This Matters
Reports a rare co-occurrence of SMAS and nutcracker phenomenon in a person with active ulcerative colitis; highlights that weight loss and obstructive symptoms in IBD may have uncommon anatomical causes.
Who Should Pay Attention
Adult patients with IBD (particularly those with weight loss and obstructive symptoms), gastroenterologists, radiologists, and surgeons.

What To Know
This is a single-case report describing a 20-year-old woman with active ulcerative colitis who was found on radiology to have both SMAS (compression of the third part of the duodenum) and left renal vein compression consistent with the nutcracker phenomenon.
The authors note that concurrent SMAS and nutcracker phenomena are extremely rare and that previous reports have linked SMAS or nutcracker to Crohn's disease but not ulcerative colitis. Management options mentioned range from nutritional support to surgical interventions; specific management chosen in this case is described in the full text.
Keep In Mind
Single-case report; descriptive evidence only. Concurrent SMAS and nutcracker phenomena are very rare and prior literature reports have mostly involved Crohn's disease rather than ulcerative colitis.
