Abstract
An 82-year-old woman had had recurrent bouts of pain from the right hip joint to the inside of the thigh since two years earlier of which cause had been unknown by close exploration performed at every bout. She developed severe pain at the same area during hospitalization in the department of medicine in our hospital for pulmonary aspergillosis, and then we were consulted. On physical examinations, an induration about 1 cm in diameter was felt at the inside of the right thigh, and there was severe tenderness at the same area. Howship-Romberg sign was positive. An abdominal CT scan showed a calcified mass 12 cm in diameter at the interstitium between the right external obturator muscle and pectineal muscle. An abdominal CT scan performed 2 years before showed a similar calcified mass about 8 mm in diameter in the pelvis at the anterior surface of the sacrum. Accordingly a peritoneal loose body might have impacted in the obturator hernia to cause a severe pain. After removal of the foreign body in the obturator hernia via inguinal approach and repair of the obturator hernia, the symptom disappeared thereafter.
We present this case in which a peritoneal loose body impacted in the obturator hernia might cause pains in the inside of the thigh, together with a review of the literature.
