Cecal infarct: report of a case.

PURPOSE: The purpose of this article is to present a case of an uncommon opportunistic fungal infection that appears in immunologically or metabolically compromised patients and is usually fatal. METHOD: A 54-year-old woman with an acute lymphoblastic leukemia had acute abdominal pain with peritoneal symptoms during her hospital stay. A laparotomy was performed and a cecal infarct firmly adherent to about 30 cm of infiltrated jejunal loop was discovered. RESULTS: Microscopic studies revealed an infiltration of the jejunal wall by abnormal lymphocytes. The cecal and ileal walls were infiltrated by leukocytes. Blood vessels were invaded by giant cells and large, unseptated, right-angle branching hyphea. CONCLUSIONS: These findings were considered typical of invasive mucormycosis of the cecum and the terminal ileum.

Congenital positional anomalies of the colon: radiographic diagnosis and clinical implications. II. Abnormalities of fixation.

Defective fixation during embryologic development is responsible for a variety of segmental colonic malpositions seen during barium enema examinations. A review of the normal development process of fixation is presented, together with the most common and significant aberrations. On the right side clinical entities such as axial torsion, cecal bascule, retrocolic sigmoid, and pericolic bands are discussed and illustrated. On the left side, the configuration and clinical implications of the malposition of the splenic flexure are analyzed. It is pointed out that reversed configurations of the splenic flexure associated with failure of fixation of the entire descending colon may occur as an isolated congenital abnormality and may not necessarily be associated with renal anomalies. The characteristic radiographic appearance of the persistent descending mesocolon and its potential for complications is in addition emphasized. Familiarization with the radiographic appearance and clinical implications of these common abnormalities is essential in the daily interpretation of barium enema examinations.

Mucinous cystadenoma of appendix concomitant with perityphlic granuloma.

We describe a case of mucinous cystadenoma of the appendix with perityphlic granuloma. The patient developed a hard palpable mass in the right lower quadrant and barium enema induced irregular bowel wall at the cecum. Based on a preoperative diagnosis of carcinoma of the appendix, we performed a laparotomy. On operation, we found a tumor mass in the region of the appendix; the mass adhered strongly to the retroperitoneum and cecum. Right hemicolectomy was carried out on a diagnosis of carcinoma of the appendix. Microscopic examination revealed mucinous cystadenoma of the appendix with perityphlic granuloma. Mucinous cystadenoma in the appendix is a rare tumor. In this patient, the tumor was accompanied by granuloma formation in adjacent tissues because of mucin expelled from the appendix. This case emphasizes that granuloma formation can make of difficult to differentiate mucinous cystadenoma in the appendix from cancer.

Radiographic features of appendiceal colic in children.

The concept of appendiceal colic was introduced in 1980 to explain the common problem of recurrent crampy abdominal pain (RAP) in children. Children with appendiceal colic often have inspissated casts of stool as foreign bodies of the appendix. The radiographic findings of 115 children operated upon for appendiceal colic have been reviewed. The radiographic features of this syndrome have included: filling defects of the appendix (83% incidence of inspissated casts of stool within the appendix); partial filling of the appendix (44% incidence of fecal casts); retained barium behind 72 h (92% incidence of fecal casts blocking egress of barium); non-visualization of the appendix (42% incidence of fecal casts); and distention of the appendix (100% incidence of fecal casts). The correlation of radiographic and operative findings will be presented. A rational approach to the radiographic workup of a child with RAP will be presented.

Drain site evisceration of the appendix: report of a case.

We report herein the case of a patient in whom evisceration of the appendix occurred at the site of a drain placed in the right lower quadrant of the abdomen. Because the appendix had become adhered to the side-hole of the drain with an external diameter of 11 mm, it was pulled out attached to the drain. Consequently, the stab wound incision of the drain was extended and an appendectomy was performed under general anesthesia. Thus, drains with a small diameter should be used whenever possible, and side-holes not having any influence on the drainage should be avoided.

Duplication of the caecum in a neonate simulating intussusception.

A case of caecal duplication in a 36-h-old neonate is described. The patient presented with vomiting and an abdominal mass and the barium enema finding was initially suggestive of intussusception. At laparotomy a duplication cyst completely obstructing the lumen was found. This was considered to have given the radiological picture simulating intussusception.

Intussusception of a mucocele of the appendix secondary to an obstruction by endometriosis: report of a case.

We treated a patient with a complete invagination of the cecum which contained a mucocele of the appendix secondary to an obstruction by endometriosis. Preoperatively, a barium enema showed a crab's claw-like area without filling in the oral side of the transverse colon. An emergency laparotomy was performed and revealed a mucocele of the appendix to have induced appendicecal invagination; however, no colonic invagination was observed. An appendicecal resection was thus done. Pathologically, the resected specimen was a mucosal hyperplasia with mucin-secreting lesions of the appendix. The theories regarding the pathogenesis of appendicecal mucocele are reviewed and discussed.

Angiodysplasia of the colon: a cause of rectal bleeding.

Colonic angiodysplasia is a vascular lesion of the colon that may become the source of low grade chronic or intermittently massive rectal bleeding. It is a lesion of the elderly, almost always found in the cecum and the ascending colon. Etiology and pathogenesis are unknown. The diagnosis can be made with angiography based on the demonstration of a vascular tuft and early opacification of draining veins. Right hemicolectomy is the mode of therapy. The lesions are minute, and in resected specimens they can be found only with special vessel injection techniques. Histologically, the lesions represent clusters of dilated vessels, mostly veins, in the mucosa and submucosa of the cecum and ascending colon.

Appendicovesical fistula.

In this study, a case of appendicovesical fistula is introduced, a really uncommon complication of acute appendicitis. This special case joins the other 102 cases which have already been described in the international literature. Due to the mild and ambiguous symptomatology, the diagnosis of this kind of fistula is difficult to be confirmed, although a serious suspicion of a vesicointestinal communication does exist. Exploratory laparotomy is usually diagnostic and leads to decisive therapy. A brief review of this clinical entity is also included.

Mucosal hyperplasia (mucocele) of the vermiform appendix. Report of a case.

Mucocele of the vermiform appendix was the term formerly used to describe all mucin-secreting lesions of the appendix. In actuality, there are three distinct clinicopathologic entities based on histologic differences. These are mucosal hyperplasia, cystadenoma, and mucinous cystadenocarcinoma of the appendix. Mucosal hyperplasia is usually an incidental finding during laparotomy for an unrelated condition. The case presented herein differed in that the patient had a three-month history of abdominal pain with nothing to suggest the presence of appendicitis, and a 3-cm opacification overlying the right iliac bone on x-ray.

Volvulus of the cecum. Report of 26 cases and review of the literature.

The management of cecal volvulus is controversial. From 1971 to 1986, 26 patients with cecal volvulus were treated at Malmö General Hospital. Treatment and patient follow-up are presented, together with a review of 350 patients reported in the literature during the past 15 years. Anatomic background and types of volvulus are described. Simple detorsion is an alternative in high-risk patients without gangrene, but resection is the method of choice also when there is no gangrene present.

Intussusception of the appendix.

Two cases of intussusception of the appendix are reported--one caused by adenocarcinoma and adenomatous polyp and the other by an endometrioma. Appendiceal intussusception and adenocarcinoma are both uncommon entities and this is the first report of the two occurring concomitantly. Due to variable symptoms, the correct diagnosis of appendiceal intussusception has rarely been made preoperatively. Classification, symptoms, radiographic appearance, and differential diagnosis are discussed, and the authors suggest a new classification for intussusception of the appendix.

Mobile cecum syndrome.

Five cases of mobile cecum syndrome are presented. These patients all presented with chronic right lower quadrant abdominal pain with associated abdominal distention and symptomatic relief after passing flatus or having a bowel movement. Three patients had preoperative barium enemas demonstrating abnormal mobility of the cecum. On exploration, all patients were found to have the cecum and ascending colon unattached to the lateral peritoneum for 15 to 18 cm. All patients were treated by cecopexy, using a lateral peritoneal flap for fixation, and all have had relief of their pain. This technique is described and illustrated. Cecopexy is an effective method of fixing the cecum and prevents subsequent cecal volvulus. The diagnosis of mobile cecum syndrome should be considered in patients with chronic right lower quadrant pain.

Herniation through the foramen of Winslow.

A patient with herniation of the cecum through the foramen of Winslow is described. Herniation through the foramen of Winslow is among the rarest of hernias. Preoperative diagnosis is unusual but is possible for the astute clinician who, on abdominal x-ray, notices air in the lesser sac with displacement of the stomach anteriorly and to the left. Treatment, of course, is prompt surgical intervention with reduction of the hernia and resection of any nonviable bowel.
