[Lumbar intercostal hernia--a rare condition].

Lumbar hernia is a rare condition, and as such often overlooked. We present a case of strangulated lumbar hernia in a 73 year-old man, with symptoms of left flank pain and a lumbar protrusion during three weeks. Diagnosis was achieved by CT scan, and a primary repair was done using a transperitoneal approach. The patient recovered well and was discharged in good condition.
