Neuronal ceroid lipofuscinosis with cardiac involvement

Cesk Patol. 2019 Fall;55(3):176-181.


Neuronal ceroid lipofuscinoses (NCLs) are a group of inherited neurodegenerative disorders with clinical presentation predominantly in the childhood. The NCLs represent lysosomal storage disorders characterized by the accumulation of autofluorescent lipopigment storage material. The most common clinical features include development failure, psychomotor regression, seizures, and progressive loss of vision. We present a case of neuronal ceroid lipofuscinosis with cardiac involvement diagnosed post-mortem in a 9,5-year-old boy, whose clinical symptomatology comprised partial epilepsy, psychomotor decline and sinus bradycardia. In contrast to ventricular hypertrophy, being more frequently associated with NCLs, we discovered cardiac atrophy. Histologic examination of the heart revealed not only the lipofuscinosis affecting cardiac conducting cells and cardiomyocytes, but also basophilic degeneration of myocardium.
