Sparganosis is caused by a larval tapeworm of the genus Spirometra, which commonly invades subcutaneous tissue, but less frequently invades muscle, intestines, spinal cord, and the peritoneopleural cavity. The authors managed a female patient who presented with a recurrent pericardiopleural effusion and peripheral
eosinophilia. The anti-sparganum-specific
IgG serum level was significantly higher than normal control levels. In this patient,
sparganosis was caused by the ingestion of raw frogs in an effort to control her
thyroid disease. The recurrent pericardiopleural effusion and peripheral
eosinophilia were controlled by 3 consecutive doses of
praziquantel (75 mg/kg/day). The patient is doing well 4 years after presentation.
Sparganosis should be considered a rare, but possible cause of recurrent
pericardial effusion and peripheral
eosinophilia. Immunoserologic testing using
enzyme linked
immunosorbent assays can be helpful in diagnosing human
sparganosis, especially in cases without a subcutaneous lump or mass.
Praziquantel is an alternative treatment for
sparganosis in surgically-unresectable cases.
