Patients usually have lived or traveled to Southeast Asia, Africa or Latin America.
Persons with light infections may be asymptomatic.
A person with a heavy infestation may experience:
(1) lung nodules or cavitary lesions with chronic cough, dyspnea and sputum that is blood-tinged or "rusty"
(2) pleuritis, pleural effusions or vague chest pains
(3) cerebral cysts with headache, meningeal signs, nausea and vomiting, paralysis, visual disturbances, sensory disturbances, seizures, subarachnoid hemorrhage and/or motor weakness
(4) migratory subcutaneous nodules or larva migrans
(5) eosinophilia
Fever, fatigue, urticaria, and diarrhea may occur after the initial incubation period.
Diagnosis:
(1) finding eggs in the sputum, stool or gastric aspirate
(2) serologic tests
(3) lung or tissue biopsy
