CEREBRAL SPARGANOSIS - INCREASED UPTAKE OF TECHNETIUM-99M-HMPAO

Cerebral sparganosis is an extremely rare intracranial parasitic infec tious disease. We report findings of Tc-99m-HMPAO cerebral perfusion S PECT in a case with cerebral sparganosis. SPECT revealed an irregularl y shaped area with markedly increased Tc-99m-HMPAO uptake in the paras itic infectious region of the cerebrum. Both white and gray matter was involved, the white matter involved predominantly. Decreased perfusio n to the right cerebellum, suggesting cross cerebellar diaschisis, was also demonstrated. This article illustrates that cerebral sparganosis is one of the causes of increased Tc-99m-HMPAO uptake in the cerebrum and should be considered clinically if present.
