RESUMO
INTRODUCTION: Neuromuscular and vascular hamartoma (NMVH) is a rare, controversial lesion of the intestine, with only 23 cases reported in the English literature since its initial description in 1982. PRESENTATION OF CASE: A 59year old female suffering from longstanding Crohn's disease with chronic stricture presented with symptoms of small bowel obstruction. Contrast studies demonstrated massive dilatation of the proximal small bowel. Laparotomy identified a 5cm long stenotic segment of ileum, with grossly distended jejunum and ileum proximally. Pathology determined the stricture's aetiology as a neuromuscular and vascular hamartoma of the small intestine. DISCUSSION: NMVH is a benign lesion of hamartomatous origin. Its very existence is questionable due to histological similarities with several reactive pathologies, such as Crohn's and diaphragm diseases. CONCLUSION: NMVH could be confused with a spectrum of chronic inflammatory bowel conditions, but this report establishes it as a distinct cause of chronic bowel obstruction.
