 Case Report | |  |
A 56-year-old male presented with a history of difficulty in passing urine to a local hospital. He was diagnosed to have benign prostatic hypertrophy and was started on alpha blockers. His symptoms gradually increased and 15 days later he presented to our hospital with acute retention of urine. Per rectal examination showed a mass behind the rectum. Abdominal examination showed a mass arising from the pelvis. He was catheterized. Routine biochemical examination was normal. Abdominal ultrasound showed a well defined heterogenous mass on the left lateral pelvic wall. Intravenous urogram (IVU) showed leftsided hydroureteronephrosis. Cystoscopy showed an extravesical growth compressing the bladder neck and trigone. Computed tomography (CT) scan the abdomen showed a large well-defined solid mass of mixed density in the presacral region measuring 122 x 92 x 86 mm extenting up to the retrovesical area towards the left side [Figure - 1]. Per rectal core needle biopsy was done which yielded cheesy material with hair in the specimen. Histopathology report was dermoid cyst. Exploratory laparotomy was done. The tumour was found occupying the presacral hollow on the left side, pushing the rectum to the right side, with no signs of infiltration into the rectum or sacrum. The tumour wall was very thin and was broken in the process of removal. The rectal wall and sacrum were normal. The abdomen was closed after peritoneal lavage. Postoperatively urinary catheter was kept for one week, and after removal, patient voided normally. Histopathology report was consistent with dermoid cyst.

The retrorectal space is an area where the neuroectoderm, the notochord, the hindgut and the proctodeum undergo remodeling and regression in embryological life. It can thus be the site of a heterogeneous group of benign and malignant tumours originating from vesical tissue derived from the three germinal layers.
Retrorectal tumours are rare. Most publications describe only individual cases. Retrorectal tumours are usually classified as congenital, inflammatory, neurogenic, osseous, or miscellaneous. [1] More than 50% of these lesions are congenital. Developmental cysts constitute the majority of the congenital lesions and may arise from any of the germ cell layers. [2] Developmental cysts often contain columnar or transitional epithelium (tailgut cysts or mucus-secreting cysts) of squamous epithelium with (presacral dermoid) or without (epidermoid) skin appendages. [1] More common in females, developmental cysts are often diagnosed in the fourth and fifth decade of life. They are often asymptomatic and are discovered incidentally during anal digital examination as a soft, compressible, illdefined mass behind the rectum. [1],[2] Some patients complain of pain, particularly when sitting. Other complaints include constipation, urinary symptoms, recurrent infection, or obstructed labour. [2] Developmental cysts can become infected and be confused with a supralevator abscess or a fistula-in-ano. [1],[2] The diagnosis is often confirmed by CT scan, magnetic resonance imaging or endorectal ultrasound. Other diagnostic tests (e.g. barium enema, siamoidoscopy, intravenous pyelogram) may be used selectively. Surgical resection is the treatment of choice, even in asymptomatic patients. Removing them will help confirm the diagnosis, exclude malignancy and prevent infection. [1],[3]
