The study aims to demonstrate the presence of a fibrous or fibromuscular ring structure within the wall of the sacs of inguinal hernia in children and its importance in the development of incarceration as a direct cause of this complication. A case series study of 784 children with unilateral inguinal hernias operated on over a period of 9 years (1992-2000) in two teaching hospitals (Mosul, Iraq). All underwent herniotomy. ⋯ Incarcerations of inguinal hernia in children are usually caused by the inguinal rings. Another cause for incarceration being studied is a fibrous or fibromuscular ring structure identified within the wall of the hernial sac, causing the incarceration in 5.6% of elective (nonincarcerated) hernias and 16% of incarcerated hernia patients. Patients with these hernia sac rings are three times more liable to incarceration than others.

Morgagni's hernia is a rare congenital diaphragmatic herniation and is usually diagnosed in childhood. It is quite rare in adults, and intestinal obstruction as a complication due to intrathoracic intestinal herniation rarely occurs. We present the plain radiography and computed tomography findings of an adult patient with acute abdomen symptoms due to Morgagni's hernia.
