Objectives: Neuronal ceroid lipofuscinosis type 11 (NCL11) is a rare disease that presents with progressive cognitive decline, epilepsy, visual impairment, retinal atrophy, cerebellar ataxia and cerebellar atrophy. We present herein a case of NCL11 in a patient diagnosed with neuromotor developmental delay, epilepsy, bronchiolitis obliterans and hypothyroidism. Case presentation: A 4-year-old male patient was admitted to our clinic with global developmental delay and a medical history that included recurrent hospitalizations for pneumonia at the age of 17 days, and in months 4, 5 and 7. Family history revealed a brother with similar clinical findings (recurrent pneumonia, hypothyroidism, hypotonicity, swallowing dysfunction and neuromotor delay) who died from pneumonia at the age of 22 months. Computed tomography of the thorax was consistent with bronchiolitis obliterans, while epileptic discharges were identified on electroencephalogram with a high incidence of bilateral fronto-centro-temporal and generalized spike-wave activity but no photoparoxysmal response. Cranial MRI revealed T2 hyperintense areas in the occipital periventricular white matter and volume loss in the white matter, a thin corpus callosum and vermis atrophy. A whole-exome sequencing molecular analysis revealed compound heterozygous c.430G>A (p.Asp144Asn) and c.415T>C (p.Cys139Arg) variants in the GRN gene. Conclusions: The presented case indicates that NCL11 should be taken into account in patients with epilepsy and neurodegenerative diseases.
