Vascular Tension Gone Wrong: Sigmoid Colon Herniation Leading to a Mesenteric Hematoma

Mesenteric hematomas, a rare and clinically significant condition, are typically associated with abdominal trauma, vascular conditions, or surgical complications. Spontaneous mesenteric hematomas, an even rarer subtype, are often seen in patients who are on anticoagulation therapy or have inguinal hernias. In this case report, we discuss an 89-year-old male patient who initially presented with stable vital signs and abdominal pain but was later discovered to have a large, stable mesenteric hematoma on an abdominal computed tomography scan. The hematoma was believed to be secondary to the herniated sigmoid colon exerting tension on the mesenteric vasculature. This case represented an unusual interaction between sigmoid colon hernias and spontaneous mesenteric hematoma formations, underscoring the importance of considering mesenteric vascular injury in patients with non-surgically managed hernias.
