Small bowel diaphragm disease is a rare complication related to non-steroidal anti-inflammatory drug (NSAID) use. It presents with non-specific symptoms such as vomiting, abdominal pain, subacute bowel obstruction and occasionally as an acute abdominal condition. We report a case of diaphragm disease in a 33-year-old female who presented with vomiting, constipation and abdominal pain started 5 days earlier. Physical examination revealed palpated abdominal mass. The patient's past medical history was remarkable for NSAID use. The patient was managed by surgical resection of involved intestine and diagnosis was confirmed by histological examination. Although there are few published cases of diaphragm disease in the medical literature, we recommend that this disease should be considered as one of the differential diagnoses when assessing patients presenting with non-specific abdominal symptoms with remarkable past medical history of NSAID use.
