Spontaneously Ruptured Idiopathic Mesenteric Hematoma: A Case Report With Review of Literature.

Ruptured mesenteric hematoma is a rare entity that is not frequently reported in the literature. Spontaneous rupture of mesenteric hematoma has been vaguely described in a handful of cases. The majority of cases (unlike ours) had a reported etiology, like trauma, postoperative complications, connective tissue disease, and coagulopathy. To our knowledge, only two cases were reported for spontaneous rupture of idiopathic mesenteric hematoma. We, herein, present a 45-year-old male presented with abdominal pain, nausea, and vomiting associated with hypotension. His investigations, including abdominal computed tomography (CT) scan, showed a large lobulated mesenteric structure involving the small bowel mesentery, representing a mesenteric hematoma. Due to suspicion of intra-abdominal bleeding; we proceeded for exploratory laparotomy. Intraoperative findings showed a large mesenteric hematoma. The patient was stabilized after the evacuation of hematoma and no specific source of bleeding was identified. Ruptured idiopathic mesenteric hematoma is an extremely rare condition that poses a diagnostic challenge, it should be kept among deferential diagnoses, especially, in unstable patients with abdominal symptoms.
