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...

RATIONALE: Myeloid sarcomas (MSs) are rare malignant hematological tumors. They most commonly occur in patients with acute or chronic myeloid leukemia. A de novo MS with no evidence of blood system disease is rare, but may represent the first sign of a systemic illness that precedes a full-blown disease. Herein, we report the computed tomography (CT) findings of an extremely rare case of a nonleukemic MS that progressed to acute myelogenous leukemia (AML) and simultaneously involved the small intestine, kidneys, mesentery, and mesenteric lymph nodes...

A previously healthy 3-week-old boy presented with 5 hours of marked fussiness, abdominal distention, and poor feeding. He was afebrile and well perfused. His examination was remarkable for localized abdominal tenderness and distention. He was referred to the emergency department in which an abdominal radiograph revealed gaseous distention of the bowel with a paucity of gas in the pelvis. Complete blood cell count and urinalysis were unremarkable. His ongoing fussiness and abnormal physical examination prompted consultation with surgery and radiology...

Mesenteric cysts are rare, benign gastrointestinal cystic lesions, which are often non-troublesome and present as an incidental radiological finding. However, surgery is often performed in the acute setting to remove lesions that are symptomatic. This report highlights the case of a large, symptomatic mesenteric cyst managed successfully with initial conservative measures followed by planned elective surgery. A 44-year-old female presented with a four-day history of generalised abdominal pain associated with distension, fever, diarrhoea and vomiting...

Pneumatosis Intestinalis (PI) is an uncommon condition in which there is gas present within the wall of the gastrointestinal tract. PI is usually found in the large bowel, but can less commonly occur in the small bowel, and gas may be present in either the subserosal or submucosal layer of the intestine. Its unfamiliarity often means it is under-recognised and not considered as a differential diagnosis when assessing a patient with abdominal symptoms. The spectrum of conditions that produce PI is varied and ranges from the non-urgent to life-threatening...

Non-Hodgkin lymphoma often involves the liver. However, primary hepatic lymphoma (PHL) confined to the liver without evidence of lymphomatous involvement is rare. The optimal therapy for PHL is still unclear. Most patients present with poor prognostic features. Here, we report a case of PHL treated with liver resection followed by chemotherapy. A 65-year-old male was referred for further evaluation about a liver mass detected on ultrasound. Abdominal computed tomography (CT) scan showed well-defined single mass of 6 cm in diameter...

BACKGROUND: Pneumatosis intestinalis (PI) is an uncommon and poorly understood condition. Although it can be an incidental finding in asymptomatic individuals, it can also be secondary to life-threatening bowel ischaemia and sepsis. In premature infants, it is a pathognomonic sign of necrotising enterocolitis. There is no consensus regarding management and long-term outcome of children with PI. AIM: Review of our experience of PI in children beyond the early infantile period...

RATIONALE: Adnexal torsion is 1 of the most common emergency gynecological disease. It is more often diagnosed in reproductive age, but rarely in postmenopausal women. The clinical symptoms of adnexal torsion are nonspecific in postmenopausal women. Epithelial ovarian tumors are common in adults, and the risk of malignancy increases with age, especially after menopause. So, it is difficult to diagnose adnexal torsion precisely compared with reproductive women, and most cases of adnexal torsion with postmenopausal women are diagnosed as a malignancy preoperatively...
