BACKGROUND: Vitamin D-resistant rickets type-IIA (VDRR-IIA) is a rare, congenital, metabolic disorder characterized by hypocalcemia, rickets, and alopecia. There are reports correlating calcium-metabolic disorders with basal ganglia calcification (BGC) and neuropsychiatric symptoms. OBJECTIVE: The authors document and discuss the relationships of these phenomena. METHOD: The authors describe a patient born with VDRR-IIA who subsequently developed BGC at age 15, and catatonic symptoms of progressive severity at age 16. RESULTS: There appeared to be a positive correlation between the severity of BGC and neuropsychiatric symptoms. DISCUSSION: This is the first time VDRR-IIA, BGC, and catatonia have been reported in a patient, and the authors discuss the relationship among the conditions.
