Cerebral cavernous angiomas: an atypical case in infancy
1Department of Child Neuropsychiatry, IRCCS, C. Mondino Foundation, University of Pavia, Italy.
Summary
This report details a rare case of cerebral cavernous angioma (CCA) in an infant, presenting with sudden neurological deficits. Prompt MRI revealed the lesion, and symptoms resolved, highlighting early-onset CCA presentation.
Area of Science:
- Neuroscience
- Vascular Malformations
- Pediatric Neurology
Background:
- Cerebral cavernous angiomas (CCAs) are uncommon intracranial vascular lesions, representing 1% of all such lesions and 15% of cerebral vascular malformations.
- CCAs can manifest sporadically or with a familial pattern, likely inherited in an autosomal dominant manner.
- This study focuses on an infant with an atypical presentation of CCA.
Observation:
- An infant born at 37 weeks gestation with a birth weight of 1560g and no significant family history presented at 10 months.
- The infant exhibited sudden onset of right arm hypotonia, motor deficits, and absent reflexes, with normal psychomotor development.
- Magnetic Resonance Imaging (MRI) identified a cavernous angioma in the paramedian pontine region.
Findings:
- The infant's neurological symptoms, including monoparesis, resolved rapidly after presentation.
- The case is notable for the early age of onset and the specific clinical manifestation of the cerebral cavernous angioma.
- The paramedian pontine location of the CCA correlated with the observed neurological deficits.
Implications:
- This case underscores the importance of considering rare vascular malformations like CCAs in the differential diagnosis of acute neurological changes in infants.
- Early detection through neuroimaging is crucial for timely management and understanding the clinical course of pediatric CCAs.
- Further research into the early-onset mechanisms and varied clinical presentations of CCAs is warranted.
