Ileal duplication cyst: Y-configuration on in vivo sonography

An ileal duplication cyst case report: From diagnosis to treatment

Enteric duplication cysts (EDCs) are rare congenital malformations of the children and can develop everywhere along the gastrointestinal (GI) tract, being the ileum the most frequent localization. We herein present an unusual case of duplication cyst of ileal origin who show a tubular morphology and doesn't communicate with GI lumen. A 2-month-old boy was admitted to our hospital for investigation of an anechoic formation of the lower right abdomen for the surgical planning. The patient was asymptomatic. Ultrasound (US) and magnetic resonance imaging (MRI) showed features of a cystic lesion. Laparoscopic surgery was performed and the cyst excised. Macroscopic examination and histologic findings confirmed the diagnosis of a enteric duplication cyst arising from the ileum. In a patient with an abdominal cystic mass, although asymptomatic, it's worth assessing the nature of the lesion and planning a surgery in order to avoid future complications. A correct use of diagnostic it's fundamental to identify the etiology and the characteristics of a cystic mass.

Enterogenous cyst of the small bowel mesentery: a case report and review of the literature

INTRODUCTION

Enterogenous cysts are a very rare congenital abnormality that can be found anywhere within the gastrointestinal tract, most commonly in the small intestine. The incidence is approximately one in 4500-10,000 live births. Diagnosis can be suggested by ultrasound (US), computed tomography (CT) scans or magnetic resonance imaging (MRI) findings, although histological examination confirms the definitive diagnosis.

PATIENTS

We present a case of enterogenous cyst in an adult female who underwent a resection of the tumour.

RESULTS

After two years of observation, there is no evidence of tumour recurrence.

Ileal Duplication Cyst Presenting With Acute Abdomen at Adult Age: Report of a Rare Case and a Review of the Literature

Gastrointestinal duplication cysts are rare lesions that typically present with acute abdomen in childhood. They are rare in adults, with only a few adult cases having been reported thus far. Adults with these lesions are usually asymptomatic or manifest with subtle abdominal symptoms. They may, however, also present with obstruction, bleeding, perforation, or malignancy. Herein, we aimed to report a case of ileal duplication cyst at adult age that presenting with symptoms of acute abdomen and reviewed the reported cases of adult age duplication cysts.

Duplication cyst of ileum presenting as acute intestinal obstruction in an adult

Duplication cysts occur because of congenital aberration during gut development. They are commonly diagnosed during infancy and rarely during adulthood. We present an adult male who presented to surgical emergency with acute intestinal obstruction. Intraoperatively, this patient was found to have a non-communicating duplication cyst of ileum causing proximal obstruction. The involved segment of the small bowel was resected and a divided loop ileostomy was created.

Ileal duplication cyst in the elderly complicated by appendicitis: A rare case report and review of literature

•

Duplication cysts seen commonly in the pediatric population is a rare entity in the elderly.

•

Surgical resection is necessary due to possible complications.

•

Laparoscopic management aids early recovery and minimum morbidity.

Introduction

Gastrointestinal duplication cysts are rare, generally found in infants and young adults. Adult presentation is rare.

Presentation of the case

We present an elderly lady who presented with right iliac fossa pain. Imaging showed a terminal ileal duplication cyst. Laparoscopic right hemicolectomy was done.

Histopathology confirmed ileal duplication cyst with reactive appendicitis.

Discussion

Surgical resection is deemed appropriate management due to known complications like obstruction, hemorrhage, perforation and malignant degeneration. Resection of only the cyst is adequate in completely isolated cases. However, others require resection of adjoining small bowel.

Conclusion

We highlight the rare occurrence in elderly and its management laparoscopically.

Ultrasound of the duodenum in children

Ultrasound is well suited for examining the pediatric duodenum, given the small size of the patients, the lack of ionizing radiation and high-resolution imaging potential. Technical considerations, normal anatomy, congenital and acquired pathology of the duodenum, and the advantages and limitations of US are discussed and illustrated in this review.

Periampullary duodenal duplication cyst masquerading as a choledochocele

Enteric duplication cysts are rare congenital anomalies of unclear etiology. While they can occur anywhere in the gastrointestinal tract, they typically occur in the ileum or ileocecal region and very rarely in the duodenum. Here, we report a case of a periampullary duodenal duplication cyst in a 13-year-old male who presented with clinical and laboratory evidence of small bowel obstruction, hepatitis, and pancreatitis. Based on radiologic imaging, the patient was thought to have a type III choledochal cyst (choledochocele) within the duodenal lumen. Intraoperative findings and postoperative pathological evaluation, however, revealed that the lesion was a duodenal duplication cyst masquerading as a choledochal cyst. Interestingly, the duplication cyst was communicating with the common bile duct, simultaneously causing biliary and small bowel obstruction.

Unusual imaging features of completely isolated enteric duplication in a child

We report a case of completely isolated enteric duplication in an 18-month-old boy in whom US revealed a reniform abdominal mass with a pseudokidney sign that had no connection to adjacent organs. Distinctive histopathological changes of the duplication account for these unusual imaging features. Our case represents a diagnostic challenge in this rare entity. To our knowledge, this is a unique case.

Unusual noncommunicating isolated enteric duplication cyst in adults

Duplication cysts are rare gastrointestinal congenital abnormalities and can occur anywhere within the gastrointestinal tract. Duplication cysts are firmly attached to or share the wall of the alimentary tract and have a common blood supply with the adjacent segment of the bowel. Completely isolated duplication cysts are an extremely rare variety of gastrointestinal duplications with their own exclusive blood supply, and they do not communicate with the intestine. These cysts are usually diagnosed during early childhood, and very rarely detected in adults, mostly incidentally, due to a lack of symptoms. A 28-year-old male was admitted to our hospital with a chief complaint of lower abdominal pain and distention and a palpable mass for 1 month. Based upon computed tomography and sonographic findings, a small bowel duplication cyst was tentatively diagnosed. The cyst had no connection to the gastrointestinal tract. Herein we report the case of a noncommunicating isolated ileal duplication cyst in an adult. Resection of the cyst was performed safely without requiring bowel resection.
