An adult female domestic shorthair cat was evaluated for chronic upper respiratory disease and vomiting. A diagnosis of idiopathic megaesophagus with intermittent gastroesophageal intussusception (GEI) was made based on radiographic and endoscopic examinations. The GEI was manually reduced by use of a stomach tube during the endoscopic procedure. An incisional gastropexy was performed to prevent recurrence. Gastroesophageal intussusception is a rare condition in cats. In dogs it is usually associated with rapid progression of clinical signs, culminating in death. In this cat, the condition was associated with chronic signs, probably due to the intermittent nature of the GEI.
A three-year-old, male neutered domestic longhair cat was referred for evaluation of icterus, vomiting, and anorexia. Abdominal ultrasonography revealed a proximal duodenal mass obstructing the common bile duct. The mass was surgically resected, and a cholecystoduodenostomy was performed. The histopathological diagnosis was osteosarcoma. Thoracic radiographs showed no evidence of metastasis, and bone scintigraphy revealed no signs of a primary skeletal osteosarcoma. Four months after surgery, the cat had intermittent vomiting, marked weight loss, and died.
A geriatric domestic shorthair cat was presented for evaluation of chronic vomiting. Chronic renal failure was diagnosed on the basis of physical examination findings and results of a serum biochemical profile and urinalysis. Endoscopically obtained gastric biopsies were suggestive of a carcinoid tumor. Subsequently, an exploratory celiotomy with partial gastrectomy was performed. Histopathological and electron microscopic analysis of surgical biopsy specimens confirmed the diagnosis of a gastric carcinoid, which has not been previously reported in the cat. Following complete excision, the cat remained clinically stable and free of signs of gastrointestinal disease for 4 months before requiring treatment for progressive renal failure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
