Abstract

The progression of basal ganglia germ cell tumor (BGGCT) is slow and insidious, and the diagnosis is often delayed. We report here an 11-year-old boy with BGGCT associated with psychomotor deterioration and excessive salivation. Serial salivary gland scintigraphy and single photon emission computed tomography suggested that the dysregulation of basal ganglia to cortical circuitry accounts for the neurological comorbidity associated with BGGCT. We also found that topical scopolamine patches are safe and effective to suppress excessive salivation.
