Abstract
Green iguanas with gastrointestinal, hepatic, and reproductive disease may present to the veterinary clinic displaying non-specific clinical signs, necessitating a thorough clinical evaluation. A 15-year-old intact female green iguana (Iguana iguana) presented with a 3-week history of decreased appetite and coelomic distension. A complete blood count and plasma biochemistry analysis showed anaemia and leukopenia with an absolute lymphopenia; decreased sodium and chloride concentrations; and increased phosphorus, potassium, aspartate transaminase, and uric acid concentrations. Whole body radiographs revealed a large, round, homogenous soft tissue opacity structure in the coelom. Ultrasonography confirmed a thin-walled cystic structure located in the cranial coelomic cavity. An exploratory coeliotomy revealed a large hepatic cyst, diffusely abnormal hepatic parenchyma, and cysts on the right ovary. The right ovary and hepatic cyst were surgically excised, however the iguana died under general anesthesia. Histopathology provided a diagnosis of multifocal cholangiocarcinoma and ovarian papillary adenocarcinoma. This case report alerts the clinician to the clinical presentation, anaesthetic protocol, surgical intervention, and challenges associated with the diagnosis of a large cystic cholangiocarcinoma in a pet green iguana.
