Pneumatosis cystoides intestinalis involving the left side of the colon has been infrequently described. The condition was recognized 234 years ago when it was discovered in a cadaver. It was not until 1946, however, that a description of this lesion appeared in the radiological literature of North America. Pathologically, it is characterized by the presence of subserosal or submucosal cysts, varying from one millimetre to several centimetres in diameter. The complications of this process are pneumoperitoneum and intestinal obstruction. Three patients are described, the first of whom had partial bowel obstruction. Radiolucent gas-filled cysts along the bowel wall were observed on the radiographs. An additional radiological sign noted by the authors was fixation and elongation of the sigmoid colon with loss of pliability of the bowel wall which persisted on the evacuation film.
累及结肠左侧的肠壁囊样积气症鲜有报道。该病于234年前在一具尸体中被发现时得以确认。然而，直到1946年，北美放射学文献中才出现对该病变的描述。病理上，其特征是浆膜下或黏膜下囊肿的存在，直径从1毫米到几厘米不等。该病症的并发症是气腹和肠梗阻。本文描述了3例患者，其中首例患者患有部分肠梗阻。X线片上观察到沿肠壁有透光的充气囊肿。作者注意到的另一个放射学征象是乙状结肠固定和延长，肠壁柔韧性丧失，排空片上该征象持续存在。
