#1
Spencer W Beasley
The umbilicus is involved in a wide range of abnormalities in infants and children. The most severe are evident at birth and include exomphalos (omphalocele) and gastroschisis, both of which can be life-threatening but are easy to diagnose. Exomphalos is often associated with other congenital abnormalities, whereas the associated problems in gastroschisis are largely confined to the gut. Infection of the umbilicus in the neonate presents as omphalitis. The causes of a moist umbilicus following separation of the umbilical stump are multiple, from the relatively minor umbilical granuloma or ectopic bowel mucosa to the more significant patent urachus that leaks urine...

INTRODUCTION: The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herniate and become obstructed. This report describes 2 rare cases of small bowel occlusion owing to an internal hernia caused by a MDB...

A 7-year-old girl with an episode of hematochezia and melena, suspicious for bleeding Meckel's diverticulum, was referred for a Tc-99m pertechnetate Meckel's scan. On dynamic planar scan, apart from prompt gastric visualization an oval-shaped, area of inhomogeneous tracer uptake was observed in the left lower quadrant of the abdomen. Subsequent single-photon emission computed tomography/computed tomography localized this to intestinal lumen, thus establishing the diagnosis of intestinal duplication (ID) with functional gastric mucosa...

BACKGROUND: Surgical removal of giant vestibular schwannomas with severe petrous bone involvement remains challenging due to the high risk of complications. The retrosigmoid intradural suprameatal-inframeatal approach (RISIA) allows for safe exposure extending from Meckel's cave to the petrous internal carotid artery (ICA). CLINICAL DESCRIPTION: A 27-year-old man presented with recurrence of a giant vestibular schwannoma (4.5 cm) invading Meckel's cave and the left petrous ICA...

Mohsen Qutbi, Isa Neshandar Asli
Quality control and technical issues are essential for high-quality imaging. An important technical parameter of image acquisition is selecting zoom factor according to camera field-of-view dimensions and patient's body size. Here, we present a case of atypically located Meckel's diverticulum mimicking bladder on Meckel scan.

There are many kinds of unusual presentations or associations and clinical mimics of acute appendicitis, and definitive diagnosis requires knowledge of the imaging findings in some cases. The unusual presentations and associations of acute appendicitis included in this study are perforated appendicitis, acute appendicitis occurring in hernias, acute appendicitis with cystic endosalpingiosis, intussusception of appendix, and acute appendicitis with pregnancy. We also present uncommon gastrointestinal, urinary and gynecologic clinical mimics of acute appendicitis including anomalous congenital band, duplication cysts, giant Meckel's diverticulitis, inflammatory fibroid polyp, renal artery thrombosis, spontaneous urinary extravasation and OHVIRA syndrome...

An 80-year-old man was examined with esophagogastroduodenoscopy and colonoscopy because of digestive tract hemorrhage;however, no specific cause was found. Small intestinal capsule endoscopy revealed a reddish elevated lesion in the ileum. This lesion was also detected using double-balloon endoscopy as a 5-cm reddish elevated lesion covered with normal villous architecture in the 95-cm part of the Bauhin valve on the oral side. The lesion was laparoscopically resected and diagnosed as inverted Meckel's diverticulum based on pathological examination...

BACKGROUND: The reported accuracy of pertechnetate scintigraphy (Meckel scan) in investigating children with a bleeding Meckel's diverticulum has increased steadily since it was first introduced into clinical practice in 1970. Recent studies have indicated that the examination has a sensitivity of up to 94% and a specificity of up to 97% in this scenario. There have also been several misleading reviews from Departments of Surgery, suggesting that the Meckel scan has a poor predictive value, and should not be relied upon to exclude a bleeding Meckel's Diverticulum (MD)...

INTRODUCTION: The frequent complications of Meckel's diverticulum are hemorrhage, intestinal obstruction, and inflammation, and perforation. The presentation as a retroperitoneal abscess as complications of Meckel's diverticulum is a very rare clinical entity. PRESENTATION OF CASE: We report a rare case of perforated Meckel's diverticulum with retroperitoneal abscess. A 31-year-old presented with a half-hour history of severe epigastric pain and diffuse periumbilical pain...

Meckel scintigraphy with Tc-pertechnetate was performed in a 5-year-old boy to determine whether a Meckel diverticulum containing ectopic gastric mucosa caused bleeding. The images did not reveal focal activity characteristic of a Meckel diverticulum. Unexpectedly, activity in the tracheobronchial tree was visualized, consistent with aspiration of the radioactive saliva.

The study was designed to investigate calcification in developing rat mandibular bone using whole mount staining, micro-computed tomography (micro-CT) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). Wistar rats at embryonic days 16, 18, and 20 and postnatal weeks 1 and 6 were used. Rats were fixed with 4% paraformaldehyde and heads were resected, frozen and sectioned for histology, then analysed with SEM-EDX. Some of the specimens were observed with micro-CT. Other rats were fixed and stained with alcian blue and alizarin red for whole mount staining...

Congenital hepatic fibrosis (CHF) is a rare, autosomal recessive disorder, clinically characterized by hepatic fibrosis and portal hypertension. CHF results from ductal plate malformation (DPM) of the intrahepatic bile ducts. Four clinical forms can be observed: portal hypertensive, cholangitic, mixed and latent. CHF is one of the "fibropolycystic diseases" which also include several conditions with a variety of intrahepatic bile duct dilatation and associated periportal fibrosis such as Caroli disease, autosomal recessive and dominant polycystic kidney disease (ARPKD or ADPKD), Ivemark, Jeune, Joubert, Bardet-Biedl, Meckel-Gruber and Arima syndromes...

A Littre's hernia is an unusual phenomenon where a Meckel's diverticulum protrudes through a potential abdominal opening. We wish to present a unique case of a 79-year-old man with respiratory distress following a fall from standing, initially managed as a haemothorax. After a chest drain was placed, bowel contents were drained from the pleural cavity and he was taken to theatre. He had a history of minimally invasive oesophagectomy for cancer and had subsequently developed a diaphragmatic hernia. A blind ending diverticulum with a perforation at its tip was found in the left oblique lung fissure that was subsequently confirmed histologically as a perforated Meckel's diverticulum...

Foreign body ingestion is a common problem in children. Most of these foreign bodies spontaneously pass through the gastrointestinal tract. When there is a persistent foreign body in the abdomen, it is impossible to make a diagnosis without exploration. We herein present the case of a child who was admitted to our hospital with a coin trapped in Meckel's diverticulum and our laparoscopic approach in this case. The diagnosis of Meckel's diverticulum should be considered when there is a prolonged lodgment of a foreign body in the right lower quadrant, and the laparoscopic approach is the preferred choice in these cases...

A Meckel's diverticulum is a common anomaly of the gastrointestinal tract. Although the majority of patients do not have any symptoms, malignancies can develop inside these diverticula, with neuroendocrine tumours being the most common. Diverticulectomy is the best option for complicated diverticula but prophylactic resection of asymptomatic diverticula in adults remains controversial. We present a case series of three patients with a neuroendocrine tumour found in a Meckel's diverticulum. Given the number of asymptomatic diverticula not resected, it seems likely that incidental neuroendocrine tumours are more prevalent than thought previously...

BACKGROUND: When clinical presentation, laboratory studies, or imaging cannot diagnose cavernous sinus (CS) and/or Meckel's cave (MC) lesions, biopsy may be necessary. OBJECTIVE: To review our institutional series of biopsies of indeterminate CS and MC lesions. METHODS: Records from January 1994 to June 2016 were searched for biopsied indeterminate CS and MC lesions. We defined indeterminate as having an atypical imaging appearance or a broad differential and the need for tissue for definitive diagnosis...

Non-Meckel small intestine diverticulitis can have many manifestations and its management is not well-defined. We report 4 unselect cases of small intestine diverticulitis; all patients were seen by the same physician at the Emergency Center at The University of Texas MD Anderson Cancer Center between 1999 and 2014. The median age at diagnosis of these patients was 82 years (range, 76-87 years). All 4 patients presented with acute onset of abdominal pain, and computed tomography scans showed characteristics of small intestine diverticulitis unrelated to cancer...

Alimentary tract duplication cysts are rare congenital anomalies, most commonly located in the ileum, but may present anywhere from mouth to anus.Clinically, they may be asymptomatic, incidentally diagnosed or may present with obstruction, volvulus, intussusception or gastrointestinal bleed. Here we report a case of a one year old male child presenting in gasping state and shock. Despite the initial strong suspicion of Meckel's diverticulum and tubercular abdomen, the final diagnosis remained elusive till exploratory laparotomy was performed which revealed a duplication cyst of ileum with perforation into the umbilicus...
