Clinical Features:
Within hours after
ingestion of infected larvae, violent abdominal pain, nausea, and vomiting
may occur. Occasionally the larvae are coughed up. If the larvae
pass into the bowel, a severe eosinophilic granulomatous response may also
occur 1 to 2 weeks following infection, causing symptoms mimicking Crohn's
disease.
Laboratory
Diagnosis:
Diagnosis can be made by
gastroscopic examination during which the 2 cm larvae are visualized and removed, or by
histopathologic examination of tissue removed at biopsy or during surgery.
Diagnostic Findings
Treatment:
The treatment
of choice is surgical or endoscopic removal. For additional
information, see the recommendations in
The
Medical Letter (Drugs for Parasitic Infections).
