A Rare Case of True Pancreatic Cyst

Pancreatic cysts can be true or pseudocysts. True pancreatic cysts in children are rare clinical entities. We present a 23-month-old boy with a cystic lesion in the distal body and tail of the pancreas which on histopathology was found to be a rare true congenital simple cyst of the pancreas.

Cystic Nontubular Jejunal Duplication Cyst Presenting As Acute Intestinal Obstruction: A Surgical Challenge

Enteric duplication cysts are rare congenital anomalies that present with a vague constellation of symptoms such as vomiting and abdominal distension. Of these, cystic nontubular jejunal duplication cysts comprise an exceedingly small subset. Here, we delineate the case of a two-month-old female baby who presented with symptoms suggestive of acute intestinal obstruction. Radiological workup divulged a cystic lesion, which was subsequently confirmed to be a cystic nontubular jejunal duplication cyst with extensive intestinal wall sharing. Surgical excision was planned but posed a remarkable surgical challenge due to intestinal wall sharing and the cyst's exceedingly fibrotic nature.

Colonic cyst in a cat presenting recurrent constipation and abdominal pain

A 5-year-old domestic short-haired spayed female cat was presented for abdominal pain and suspended defecation. Abdominal radiographs confirmed constipation; abdominal ultrasonography showed a cystic oval structure attached to the colon. The structure exhibited a well-defined wall, composed of three layers. Its content was mildly echogenic and inhomogeneous. Laparotomy was performed and complete resection of the structure, and of part of the colon, was required (end-to-end anastomosis). Histopathology confirmed the structure to be a cystic formation of the colon with some areas of mucosal metaplasia. However the question whether the cystic structure was consistent with an intestinal duplication cyst - which is the most likely type of cyst in this particular case - a Meckel's diverticulum remnant, a vitelline duct cyst or a cystic diverticulum of the colon could not be resolved. Postoperatively, no further other episode of constipation occurred.

Recurrent hemoptysis and a mass in the thorax in an infant: the split notochord syndrome

Split notochord syndrome is a rare group of developmental abnormalities caused by abnormal splitting or deviation of the notochord clinically resulting in the duplicated bowel associated with vertebral anomalies. We report on a case of 11-month-old female infant with mediastinal hyperechogenic cyst and intestinal duplication cyst associated with T5-T6 hemivertebrae, scoliosis, and nonfusion of posterior part of T6 vertebrae, presenting with severe hemoptysis and hematemesis. The cysts were surgically removed, and histopathologic analysis revealed that the mediastinal cyst was lined by gastric mucosa and intestinal one was lined with gastric mucosa including ectopic pancreatic tissue. After removal of the lesion the patient made an uneventful recovery and shows no signs of long-term pulmonary sequelae.

Reduplication cyst of appendix with mucinous carcinoma and Müllerian metaplasia: a case report

This report describes a case of mucinous carcinoma and Müllerian metaplasia arising within an appendiceal duplication cyst found incidentally during an emergency Caesarian section. Intestinal duplication cysts are rare and although there are occasional reports of malignant transformation, this is the first case where Müllerian metaplasia was found concurrently with a malignancy. There was no previous history of endometriosis and no other abnormalities were found at surgery. Treatment included surgical excision. The patient is alive and well two years after removal of the cyst.
