Core Tip

Core Tip: Tumors (paraneoplastic) are one of the etiologies of autoimmune encephalitis (AIE). However, there are no reports of AIE occurring after surgery for appendiceal cancer. This report we describes a 47-year-old man who was transferred to our hospital due to a recurrent low intestinal obstruction and a right hemi-colectomy was performed with an ileo-transcolon anastomosis and laparoscopic exploration. But he developed a disturbance of consciousness on postoperative day 6, and diagnosed with AIE at last. We report this case in the hope of giving some guidance to clinicians with similar challenging cases.
