Obturator hernia (the little old lady’s hernia) diagnosed via computed tomography: a case report

Obturator hernia is an infrequent clinical entity of abdominal wall hernia, accounting for an incidence rate ranging from 0.073 to 2.2% of all hernias and being responsible for 0.2–1.6% of all cases of mechanical intestinal obstruction. The computed tomography (CT) scan, as an imaging modality, is critical in improving the diagnostic rate of obturator hernia. CASE PRESENTATION: The authors herein report an 87-year-old thin male patient with a known history of chronic obstructive pulmonary disease who presenting with complaints of abdominal pain for 3 days and constipation for 2 days, as well as one episode of vomiting without any features of peritoneal irritation, which was diagnosed early as a right-sided obturator hernia via CT and managed with exploratory laparotomy with hernia reduction and polypropylene mesh repair. DISCUSSION: Obturator hernia is a rare surgical phenomenon with a varied clinical spectrum, ranging from asymptomatic to presenting as intestinal obstruction. The CT scan plays a critical role in the detection of obturator hernias, which ameliorates the possible significant postoperative morbidity and mortality. CONCLUSION: This report demonstrates that a high index of suspicion combined with CT imaging aids in early diagnosis and management, thus overcoming the reluctant morbidity.
