Abstract:
Segmental absence of intestinal musculature (SAIM) was first identified as a cause of intestinal perforation and remains difficult to diagnose clinically. Diagnosing SAIM preoperatively can be difficult; however, detection during the surgical procedure may be feasible if gross observations reveal bowel alterations such as a thinned-out wall, signs of gangrenous changes, or adjacent bowel dilatation. A final diagnosis can be made with the help of histopathology, making it a gold standard. Even though this condition is more prevalent among newborns, only a handful of cases have been published in the literature, mentioning involvement of the older patients. Maintaining a high index of suspicion for this disease when dealing with cases of intestinal obstruction or perforation in children and adults is instrumental in facilitating swift diagnosis and prompt treatment, thus improving the patient's outcome. We, hereby, would like to add one more case report of a 4-year-old girl child presenting with this rare entity to the literature.

Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
