A rare delayed-onset cavernous angioma (a type of brain vascular malformation) was observed four years after surgical removal of a brain lesion. This suggests an early, undetected micro-malformation may precede symptomatic cavernous angiomas.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Cavernous angiomas are vascular malformations that can occur in the brain.
  • Delayed or late-onset cavernous angiomas are infrequently reported.
  • Previous surgical intervention in the brain may be a factor in their occurrence.

Observation:

  • A 46-year-old woman presented with a right fronto-singular cavernous angioma.
  • The lesion appeared four years after the surgical excision of a right rolandic lesion.
  • Radiological findings were consistent and confirmed by histological examination.

Findings:

  • The case highlights a delayed appearance of an intra-cerebral cavernous angioma.
  • Histological examination confirmed the diagnosis.

  • Literature review suggests possible mechanisms for delayed onset.

    • Implications:

    • The study proposes an 'infraradiologic stage' of micro-malformations.
    • This stage may involve abnormal capillaries preceding overt hemorrhage or fibrosis.
    • Further research into early-stage vascular malformations is warranted.
