ABSTRACT
Cerebral cavernous malformation 3 (CCM3) is a vascular malformation disorder causing brain slow-flow vascular parenchymal lesions. These lesions are the result of variants in the Programmed Cell Death Protein 10 (PDCD10) gene, located on 3q26.1. We report an 8-month-old patient who was presented with seizures and intracranial abscesses and was found to have a variant of PDCD10 on whole exome sequencing, representing, to our knowledge, the youngest case of CCM3 described in the literature. Her clinical course was complicated by the development of neutropenia, requiring granulocyte colony-stimulating factor, and thrombocytopenia, requiring intermittent platelet transfusions, with later development of B acute lymphoblastic leukemia 2 years after initial presentation. This case represents the first description in the literature of hematologic complications in the setting of CCM3. We hypothesize that these hematological manifestations are the result of alterations in the actin and microtubule cytoskeleton, affecting the process of hematopoiesis in a similar fashion to the documented effect of the PDCD10 variant on neuronal migration.
