Diagnosis With Brief Discussion
- Diagnosis
- Visceral lava migrans of Toxocariasis
- Radiologic Findings
- On the follow up studies, migrating patchy ground glass opacities are noted. CT findnigs are not quite different from other eosinophilic pneumonias (random distribution, GGO with consolidation or nodules, pleural effusion(28%), pneumothorax (9%)). This patient had a history of ingestion of raw cow liver.
- Brief Review
- Chops of raw cow liver are one of the popular dishes in some restaurants or buffets in Korea. Chops of raw cow liver are usually served along with usual cooked or barbecued meat. Some people believe that raw liver and meat are good for health, particularly for eyesight.
Like animals, human infections may take place in 2 ways: 1) ingestion of embryonated eggs, and 2) transfer (ingestion) of encapsulated larvae of T. canis in the tissues of a paratenic host. In certain ethnic groups, some adults tend to eat uncooked animal tissues which contain encapsulated infective larvae. After swallowing, the encapsulated larvae are liberated after hatching in the small intestine, penetrate the intestinal wall, get into the portal vein, and then reach the liver and lungs. They again become encapsulated and remain alive for a certain period. Uncooked livers of cow, pig, lamb, and chicken have been reported as sources of human infections.
High parasitic loads or repeated infection can lead to visceral larva migrans (VLM).VLM is primarily diagnosed in young children, because they are more prone to exposure and ingestion of infective eggs.[
