Adult colonic intussusception is rare and often originates from neoplasms. In emergency situations it can be difficult to diagnose. Our aim was to show how the integration of readily available diagnostic means in emergency situations can help in making a correct diagnosis of this disease. A 68-year old male patient presented with vomiting and abdominal pain. The abdomen was distended, with pain to palpation in the left quadrants without a mass. Plain radiographs of the abdomen showed a large amount of gas in the small bowel and in the right and transverse colon. A barium enema demonstrated an endoluminal filling defect in the descending colon. Abdominal ultrasonography revealed the presence of intraperitoneal fluid and thickened left colonic wall at the site of the lesion, with an aspect of a "double ring" consistent with intussusception. A solid formation was also revealed at a point distal to the thickened colonic wall. At emergency laparotomy an approximately 8-cm-long mass was palpable through the left colon. A colostomy was fashioned, and subsequently colonoscopy revealed the presence of a left colon tumor. At the subsequent operation an invagination of the left transverse colon into the descending colon was confirmed. The left transverse and descending colon were resected with high ligation of the left colic artery. Macroscopic examination of the invaginating head showed a vegetating transverse colon neoplasm. We conclude that in emergency settings the association of readily available diagnostic means such as plain abdominal radiography, water soluble contrast enema and ultrasonography may yield reliable information for diagnosing colonic intussusception.

Colitis cystica profunda is a rare intestinal lesion. Because of its clinical expression (rectorrhagia, mucorrhea and abdominal pain) and the way it appears to current imaging techniques this disease presents features which can be associated with colon neoplasm. Its diagnosis has to be confirmed histologically, and its etiology remains unclear. The following is a case report of colitis cystica profunda recurring 20 years after a first episode in a white woman, who had had an anterior resection of the sigmoid colon and upper rectum to deal with a colitis cystica profunda-induced stenosis of the sigmoid colon and at 41 underwent the transanal removal of a polypoid lesion. A review of 20 cases in the literature showed that colitis cystica profunda has a predilection for the male and generally affects the medial and lower rectum and the sigmoid colon. The literature also confirmed the association with ulcerative rectocolitis, Crohn's disease and rectal prolapse. The type of treatment varies from surgical, medical, and endoscopic to no treatment at all.

Since colonic tuberculosis is uncommon and its bifocal pseudo-tumor form is exceptional, differential diagnosis with the colonic cancer is exceedingly difficult. The purpose of this report is to describe a case of primary colonic tuberculosis in two separate locations discovered in a patient presenting with persistent massive hematochezia. A 69-year-old woman was examined for hematochezia, abdominal pain and recent weight loss. Colonoscopy revealed the presence of two ulcerated tumor-like lesions in right colon. One of these lesions caused significant stenosis. Histological examination of biopsy specimens was inconclusive. Colonic tumor with bleeding was considered as the most likely diagnosis. Surgical exploration demonstrated one tumor in the cecum and another in the ascending colon. Right hemicolectomy was performed. Histological examination of the surgical specimen demonstrated a granulomatous reaction pattern with caseous necrosis. Conventional antituberculosis treatment led to clinical improvement.
