Myxedema megacolon is rare; usually, it manifests with abdominal distention, flatulence, and constipation. Herein we describe a 72-year-old man who had intermittent diarrhea, bloating, and abdominal pain for more than a year. Cultures of stool specimens for Clostridium difficile enterotoxin were variably positive and negative. Colonoscopic biopsy specimens were thought to be consistent with chronic ischemia. Thyroid function tests showed severe hypothyroidism; the patient's symptoms resolved with thyroid hormone replacement. We hypothesize that gross dilatation of the colon, attributed to myxedema, was followed by intestinal ischemia and complicated by recurrent episodes of pseudomembranous colitis. A review of the relevant literature is provided. This unusual manifestation of myxedema should be considered in the differential diagnosis when a patient has diarrhea, bloating, and abdominal pain.

A 35-year-old nulliparous woman underwent uterine artery embolisation (UAE) for heavy menstrual bleeding and anaemia due to fibroids, refractive to medical and surgical treatment.Bilateral UAE was performed after cephazolin prophylaxis and analgesia. Postoperatively, pain and abdominal bloating were prominent. Symptoms were initially treated as postembolisation syndrome, and analgesia was escalated. By the third day, pain was worsening and the woman developed marked tachypnoea and tachycardia, with raised inflammatory markers and lactate. An abdominal X-ray and CT showed dilated colon. A colonoscopy demonstrated severe mucosal ulceration down to the muscular layer.A subtotal colectomy and end ileostomy formation was performed with intraoperative findings of toxic megacolon with near perforation. The cause of the toxic megacolon, in the absence of previous bowel pathology, was attributed to pseudomembranous colitis as a consequence of single dose prophylactic antibiotic.
