# When bullets unmask hidden fire: a rare case of undiagnosed small-vessel vasculitis revealed by dual surgical emergencies

## TL;DR

A gunshot wound led to the discovery of a hidden, life-threatening blood vessel disease that caused sudden bowel problems in a previously healthy man.

## Contribution

Highlights a rare case linking trauma to the diagnosis of undiagnosed systemic vasculitis.

## Key findings

- A gunshot wound revealed undiagnosed small-vessel vasculitis in a 36-year-old man.
- The patient later developed ischemic bowel, confirmed by laparotomy and histopathology.

## Abstract

A 36-year-old previously healthy male presented with a gunshot wound to Zone II of the right neck. Surgical exploration revealed no major injuries, and recovery was initially uneventful. However, 48 hr later, the patient developed signs of acute abdomen, prompting an exploratory laparotomy that uncovered 150–180 cm of ischemic small bowel and pale, patchy lesions suggestive of vasculitis. Histopathology confirmed necrotizing vasculitis of small and medium vessels. This case illustrates how an incidental trauma led to the diagnosis of a silent but life-threatening systemic disease. The coexistence of vascular trauma and spontaneous ischemic bowel highlights the importance of considering systemic vasculitides in patients with unexplained abdominal findings, even when presenting with an unrelated surgical emergency.
