The basophilic intermyofibrillar network was increased by multiples fibres forming small round basophilic deposits, which were PAS-positive according to enzymatic oxidation methods. This disease presents no sex-related differences and it is predominantly found in southern European countries. Results from the lysosomal enzyme study were also unremarkable. Brain MRI showed moderate overall cerebral and cerebellar atrophy.
During the following months, he presented several generalised tonic-clonic seizures. Axillary skin biopsies Fig. He had a healthy brother 3 years older.
