Diagnosis Angiostrongylus cantonensis A diagnosis of A. History of ingestion of raw or undercooked intermediate hosts or possibly transport hosts is a crucial clue as well.

Pathology[ edit ] Pathology is due to both the adults and the eggs. Adults in the ileo-caecal arterioles cause an inflammatory eosinophilic response in humans. In the Cotton Rat the adult worms cause local haemorrhages.

The intestinal wall is also affected. In humans there is a thickening of the intestinal wall ileum, appendix and caecum. In rats with heavy infestations there is a yellow discolouring of the surface of the intestinal walls.

Clinical signs and diagnosis[ edit ] Abdominal pain which presents as a palpable mass on clinical examination Anorexia Diarrhoea Vomiting In the blood and tissue biopsy there is eosinophilia. Other methods of diagnosis from a biopsy are eggs and larvae in the blood vessels.

Imaging of the liver and intestine can also be helpful. Serology is sometimes used to diagnose from a blood sample and there are specific enzyme-linked immunosorbent assays ELISA. This is a rare disease. In Martinique , a French island of the Antilles , two confirmed cases and two probable cases were identified during an year period , with an estimated incidence of 0.
