A 55-Year Old Man with Acute Painful Flank Mass, a Case Report

Lumbar hernias (LH) accounts for less than 1.5% of total hernia incidence. It can occur in two separate triangular areas of the flank. About 300 cases have been reported in the literature. Here, we report a 55-year old man with acute painful left side flank mass and final diagnosis of LH. The mass was appeared about three hours before ad-mission and his pain was slight at first but became more severe gradually. He had stable vital sign and the only positive finding on his physical examination was the sphere shape, firm, mobile, and mild tender mass at his left flank.
