Unusual disappearing abdominal bump: spigelian hernia.

ABSTRACT: Spigelian hernia is a rare surgical entity. The presentation is nonspecific, and the diagnosis is evasive if a high index of suspicion is not maintained, more so in obese patients. Contrast enhanced computed tomography (CECT) is the imaging modality of choice. Ultrasound is less specific with high false negative rate especially in obese patients. Though these hernias are managed by both open and laparoscopic approaches, the optimal mode of management is still controversial. We present a case of spigelian hernia and discuss its diagnosis and management strategies.
