Non-traumatic lateral abdominal wall hernia

Abstract

A rare lateral abdominal wall hernia is described in an adult patient. This was diagnosed in a patient with a prominent right lateral abdominal wall deformity. The patient had been experiencing pain that increased progressively in severity over time. A computerized tomography (CT) scan of the abdomen revealed the location of the lateral abdominal wall defect. The hernia defect was through the transversus abdominis and the internal oblique, with the inferior aspect of the 11th rib forming part of the superior border of the defect. A 4-cm bony spur from the inferior aspect of the rib formed part of the lateral margin of the defect. The hernia sac was contained within a space underneath the external oblique muscle. The association of the hernia defect with a bony spur was highly suggestive of a congenital etiology. The hernia was successfully repaired laparoscopically with Parietex mesh (Sofradim, Lyons, France), and the patient had resolution of the symptoms on discharge and follow-up visits.

A rare nonincisional lateral abdominal wall hernia

“…In the literature, to our knowledge, Castillo-Sang et al [ 2 ] only reported a similar type of hernia like the present case. They reported a 56-year-old male who presented a right lateral abdominal wall bulge in the midaxillary line immediately below the rib cage.…”

“…Nonincisional lateral abdominal wall hernia (LAWH) is a very rare condition, although incisional hernias along the lateral abdominal wall incision can occur infrequently [ 1 , 2 ]. LAWH has to be differentiated from other rare types of hernias such as lumbar hernia or spigelian hernia.…”

Non-traumatic hernia of the lateral abdominal wall in a patient infected with the human immunodeficiency virus

“…There are several classifications for abdominal hernias: non-traumatic LAWH, congenital lateral abdominal defect, and traumatic LAWH. 1 The LAWH described here was an unusual type of hernia. Castillo-Sang and colleagues 1 reported the first case of a LAWH in a 56-year-old male in 2008.…”

Congenital lateral abdominal wall hernia

“…Hernias of the lateral abdominal wall have been reported only in adult patients, describing its location in the axillary midline just below the rib cage.…”
