Spigelian hernia.
The clinical diagnosis of Spigelian hernia can be difficult due to lack of specific and constant findings. We report two patients whose only symptoms on presentation were progressive abdominal pain and intermittent palpable mass. The radiographic demonstration of bowel extending outside the expected confines of the peritoneal cavity allowed prompt diagnosis and proper operative management in both patients. Spigelian hernia requires surgical correction to prevent complications of acute abdomen with strangulation or incarceration.
