Obturator hernia: A diagnostic challenge

Female, 90 FINAL DIAGNOSIS: Obturator hernia Symptoms: Epigastric pain • vomiting

- Clinical Procedure: - Specialty: Gastroenterology and Hepatology.

Challenging differential diagnosis.

Obturator hernia (OH) can be difficult to diagnose because it shows only nonspecific signs and symptoms. Although pain in a lower limb caused by compression of the obturator nerve by the hernia in the obturator canal (Howship-Romberg sign) is a characteristic sign, its presence is rather rare.

We herein describe the case of a 90-year-old woman with an OH that was difficult to diagnose because of her slight abdominal signs and symptoms on admission and subtle abdominal computed tomography (CT) findings. Although the CT images revealed the presence of an OH, this finding was overlooked because it contained only a part of the small intestine wall, which is called the Richter type. Fortunately, her condition improved dramatically with only conservative treatment.

Although early diagnosis is essential to reduce morbidity and mortality, OH can be a diagnostic challenge even with abdominal CT.
