Acute gastric dilatation is a rare entity, with varying aetiologies the majority of which are benign. Delay in diagnosis and treatment could result in sequelae such as gastric emphysema (pneumatosis), emphysematous gastritis, gangrene, and perforation. Gastric emphysema as a result of a benign nongangrenous condition such as gastroparesis, adynamic ileus can be successfully managed conservatively. Here, we present an interesting case of acute gastric dilatation resulting in gastric emphysema following massive postpartum hemorrhage.

Gastrointestinal tract perforations can occur for various causes such as peptic ulcer, inflammatory disease, blunt or penetrating trauma, iatrogenic factors, foreign body or a neoplasm that require an early recognition and, often, a surgical treatment.Ultrasonography could be useful as an initial diagnostic test to determine, in various cases the presence and, sometimes, the cause of the pneumoperitoneum.The main sonographic sign of perforation is free intraperitoneal air, resulting in an increased echogenicity of a peritoneal stripe associated with multiple reflection artifacts and characteristic comet-tail appearance.It is best detected using linear probes in the right upper quadrant between the anterior abdominal wall, in the prehepatic space.Direct sign of perforation may be detectable, particularly if they are associated with other sonographic abnormalities, called indirect signs, like thickened bowel loop and air bubbles in ascitic fluid or in a localized fluid collection, bowel or gallbladder thickened wall associated with decreased bowel motility or ileus.Neverthless, this exam has its own pitfalls. It is strongly operator-dependant; some machines have low-quality images that may not able to detect intraperitoneal free air; furthermore, some patients may be less cooperative to allow for scanning of different regions; sonography is also difficult in obese patients and with those having subcutaneous emphysema. Although CT has more accuracy in the detection of the site of perforation, ultrasound may be particularly useful also in patient groups where radiation burden should be limited notably children and pregnant women.

Platypnoea orthodeoxia is a rare clinical syndrome characterised by dyspnoea and deoxygenation exhibited in upright position with improvement in supine posture. Previously described aetiologies include cardiac (pericardial effusion or constrictive pericarditis), pulmonary (pneumonectomy, emphysema or amiodarone toxicity), abdominal (cirrhosis or ileus) or vascular (abdominal aortic aneurysm) causes. We report an unusual case of platypnoea orthodeoxia associated with patent foramen ovale and partial hepatic resection.

The incidence of colon ischemia has increased in recent years, and is associated with high morbidity and mortality. The typical presentations of colon ischemia include abdominal pain, bloody diarrhea, and in severe case, ileus, fever and peritonitis. Here, we document a rare case of colon ischemia presenting with subcutaneous and intramuscular emphysema of the thigh. A 76-year-old woman presented to the emergency department for left thigh pain for three days. Physical examination revealed tenderness without obvious crepitus, erythema or swelling over the left groin area and a soft abdomen without tenderness. Plain abdominal film showed abnormal gas formation at the left thigh and chest film demonstrated subphrenic free air. Abdominal computer tomography found sigmoid perforation causing left retroperitoneal abscess, and subcutaneous and intramuscular emphysema over the left pelvic and thigh region. During operation, irreversible ischemia from the terminal ileum through the cecum to the sigmoid colon with gangrene and retroperitoneal abscess were found. Total colectomy with end ileostomy and peritoneal toilet were performed. However, massive bloody ascites from abdominal drainage developed on the 13th day of admission. She later passed away due to hemorrhagic shock. In conclusion, emphysema of the thigh may rarely be caused by an intestinal lesion, such as colon ischemia. Clinicians should be alert of these unusual presentations to find the hidden underlying etiologies.
