Visual Hallucinations in a Patient with Adult Onset Acid Maltase Deficiency Disorder

By Ritesh Patil and Jack L. DePriest

Abstract

A 66-year-old male presented with visual hallucinations. He had chronically elevated serum creatine kinase (CK) levels without muscle weakness. His hospital course was complicated by hypercapnic respiratory failure requiring mechanical ventilation. His hallucinations completely subsided on mechanical ventilation. Elevated CK levels prompted a muscle biopsy, which showed myopathy consistent with acid maltase deficiency disorder (AMDD). This is the first reported case of adult onset AMDD presenting with psychiatric symptoms. Our objective in reporting this case is to encourage early recognition of neuromuscular respiratory failure in AMDD and to reinforce that respiratory failure may develop without associated extremity muscle weakness
