1/528. MR imaging of complex tail-gut cysts.

    Retrorectal-cyst hamartomas (RCH) are rare developmental tail-gut cystic tumours of the retrorectal space, which occasionally undergo malignant transformation. We describe the magnetic resonance imaging (MRI) findings in two patients with RCH and in a third patient with unclassified sarcoma arising from a RCH. The RCH were hypointense or hyperintense on T1-weighted images and hyperintense on T2-weighted images; they did not enhance and they contained multiple septations. A solid component in the periphery of one cyst was markedly hypointense on T2-weighted images in keeping with fibrous material. The sarcoma arising from the wall of the RCH enhanced and was of intermediate signal intensity on all sequences. MR may help establish the diagnosis of RCH if an unenhanced cystic tumour is discovered in the retrorectal space and it can help detect those rare cases of malignant transformation of these developmental tumours.

2/528. Perirectal cystic paragonimiasis: endorectal coil MRI.

    We report the transrectal ultrasonographic (TRUS) and endorectal surface coil MR findings for paragonimiasis involving the perirectal space. The patient presented with voiding difficulty. TRUS showed a well demarcated, oval-shaped hyperechoic mass in the perirectal space. On endorectal MR images, the lesion was depicted as a well defined cystic mass with homogeneous intermediate signal intensity on T1-weighted images and heterogeneous hyperintensity on T2-weighted images. Ectopic paragonimiasis can appear as a well defined cystic mass in the peritoneum and should be included in the differential diagnosis of cystic mass in the abdomen and pelvic cavity, including the perirectal space.

3/528. Primary pulmonary sporotrichosis.

    A case of pulmonary sporotrichosis is described with secondary involvement of the rectum which was misdiagnosed as tuberculosis for a number of years. The authors suggest that every nondiagnosed chronic cavitary disease in the lung should include appropriate tests for sporotrichosis. ( info)

4/528. Retrorectal cystic harmatoma (tailgut cyst) in an infant: case report.

    We report the case of a day old infant who presented with a large cystic swelling in the sacroccoygeal area distorting the gluteal folds and displacing the anus anteriorly. Rectal examination revealed less than twenty five per cent of the lesion in retrorectal space, plain x-rays did not show any calcification. The infant had excision surgery at seven days of age and did well thereafter. Although most TGC cases were reported in adults the present case fulfills the anatomical and histological criteria for diagnosis, and it may be the first such case in a child less than one month old.

5/528. endometriosis: a clinically malignant disease.

    According to the literature this is the first patient with the primary diagnosis of an endometriosis (EMT) based on the cardinal symptom of an uremia in combination with a colorectal ileus. Operative removal of EMT was possible after hormonal suppression with Dienogest. ( info)

6/528. intussusception in infants: an emergency in diagnosis and treatment.

    intussusception is an important cause of intestinal obstruction and bowel necrosis in infants under 2 years. Most frequently the ileocaecal junction is involved. Various aetiologic factors, such as Meckel's diverticulum and lymphoid hyperplasia have been identified. Hydrostatic reduction of the intussusception should be attempted, but delay in diagnosis frequently leads to surgical intervention, because of failing reduction. We report a case of a 4-month-old boy whose ileocaecal junction was intussuscepted into the rectum, and therefore could be palpated by rectal examination. Unsuccessful hydrostatic reduction and bowel necrosis because of delay in diagnosis, made surgical intervention necessary. A terminal ileostomy was performed. A second case report considers a 10-month-old boy whose ileocaecal junction was intussuscepted into the colon sigmoideum. Because there was no delay in diagnosis, this intussusception could be reduced hydrostatically. The procedure however was difficult because of a dolichosigmoideum. Recent literature is also reviewed.

7/528. Fatal clostridium sordellii ischio-rectal abscess with septicaemia complicating ultrasound-guided transrectal prostate biopsy.

    clostridium sordellii is a Gram-positive spore-forming anaerobic bacillus rarely encountered in human infection. A case of C. sordellii ischio-rectal abscess with rapidly fatal septicaemia is described which complicated ultrasound-guided transrectal biopsy of the prostate, despite ciprofloxacin prophylaxis. Neither C. sordellii ischio-rectal abscess nor ischio-rectal abscess complicating transrectal biopsy have been reported previously. Judging from our experience and the reviewed literature, the addition of prophylactic anti-anaerobe drugs should be strongly considered until an optimal prophylactic regimen will be defined by randomized controlled trials.

8/528. US and CT findings of rectal amebian abscess.

    An interesting case of rectal amebic abscess is presented. Ultrasound and CT images provided the diagnosis of a cystic intramural mass at the rectal wall of a young man, who complained of pelvic pain, constipation, and fever. His clinical history of amebiasis and the finding of trophozoids and cysts at the stool swap confirmed the diagnosis. Intravenous metronidazole therapy cured the disease and led to total disappearance of the mass, and clinical well-being. ( info)

9/528. adenocarcinoma within a rectal duplication cyst: case report and literature review.

    Intestinal duplications are uncommon but recognised developmental anomalies. Duplications of the rectum are the most uncommon of these anomalies. They may present with perianal fistulae, bleeding, a pelvic mass or symptoms produced by a mass, or, rarely, malignant change. We present a case of an adenocarcinoma within a rectal duplication cyst which was initially thought to be inoperable but was treated by radical surgery. ( info)

10/528. Sigmoidofiberscopic incision plus balloon dilatation for anastomotic cicatricial stricture after anterior resection of the rectum.

    We describe the procedure and examine the therapeutic efficacy of a combination of sigmoidofiberscopic incision plus balloon dilatation for tubular stricture by thick, long scar tissue at the colorectal anastomosis after anterior resection for rectal cancer. Balloon dilatation alone does not always relieve the strictures, although this method is the usual therapy for this condition. Five patients were identified in whom the stricture was not improved with balloon dilatation alone. Of these five patients, three complained of difficulty defecating, a feeling of incomplete evacuation, residual feces, and lower abdominal fullness. The remaining two patients, who had transverse colostomy to treat major leakage at the anastomosis, showed no symptoms. All five patients underwent the combination therapy described below. Two or three small radial incisions were made in the scar of the stricture with electrocautery under fiberscopic vision. Then the strictural scar was split and loosened bluntly along the incisions over a 15- to 20-minute period with a balloon dilator. This procedure was performed once or twice at a 2-week interval. In all five patients the stricture was improved according to objective criteria. There was also an improvement in the subjective symptoms suffered by three patients. The improvements were maintained over observation periods of 9 to 15 months. No complications were observed. Sigmoidofiberscopic incision plus balloon dilatation is an effective, safe therapy for cicatricial strictures after anterior resection for rectal cancer when the strictures have failed to improve following balloon dilatation alone.
