Abstract
Paracecal hernia is a rare disease among internal hernia, and preoperative diagnosis is very difficult. Computed tomography (CT) is useful for an accurate diagnosis of paracecal hernia. Paracecal hernia is often classified into the following four types : (1)superior ileocecal, (2)inferior ileocecal, (3) retrocecal recess, and (4) appendicular fossa.
The present case was a lateral type of paracecal hernia, which could not be classified as shown above. The Meyer's classification was more suitable for our case than the conventional classification.
CT findings were very characteristic of a lateral type in the Meyer's classification. Both the ileocecum and the ascending colon were displaced medially by the dilated small-bowel loop trapped in the hernia pouch as shown in the CT images.
Patients diagnosed with paracecal hernia often need to undergo emergent surgical treatment. CT examination is useful for the diagnosis of paracecal hernia when paracecal hernia is suspected.
