we studied two siblings with Hallervorden-Spatz syndrome. Fe-uptake and disappearance studies of the brain utilizing a narrow-field-of-view collimator indicated iron retention in the basal ganglia. Ferrokinetic studies utilizing 31Cr or 59Fe are within normal limits. Hematologic abnormalities heretofore unreported in Hallervorden-Spatz syndrome included sea-blue histiocytes in bone marrow and cytoplasmic inclusions in circulating lymphocytes, consisting of vacuoles, fingerprint profiles, multilaminar profiles, granular osmiophilic deposits, curvilinear bodies, and increased numbers of tubular arrays. These findings demonstrate extracerebral manifestations of Hallervorden-Spatz syndrome that may aid diagnosis and shed light on the etiology.
