HHT Patient Cases with Polymicrogyria and Brain AVMs

Seven new clinical cases demonstrate an association between hereditary hemorrhagic telangiectasia (HHT), polymicrogyria, and brain arteriovenous malformations. The data includes patient genetics and imaging findings, supporting a theory linking specific endoglin mutations to focal cortical malformations. Analysis suggests these malformations are characteristically unilateral and correlate with low fluid shear stress during fetal brain development.

Use Cases

• Analyze the spatial proximity between polymicrogyria and brain AVM locations from patient imaging data.
• Correlate specific endoglin mutation types with the presence of polymicrogyria in HHT patient genetics.
• Investigate the unilateral and focal characteristics of polymicrogyria described in the case findings.
• Study the proposed association between low fluid shear stress during corticogenesis and later malformation development.

Strengths

• Data includes seven new, detailed clinical cases of a rare neurological association.
• Findings integrate patient genetics, imaging data, and a review of previously reported literature.
• Proposes a specific mechanistic theory linking endoglin mutations to aberrant angiogenesis.

Limitations

• Small sample size of seven cases limits statistical power and generalizability.
• Data scope is restricted to a specific, rare disease association (HHT with polymicrogyria).
• Relies on retrospective case analysis rather than a prospective, controlled study design.
