A rare diffuse arteriovenous malformation (AVM) in a child caused neurological issues. Imaging revealed progressive calcification, mimicking Sturge-Weber syndrome.

Area of Science:

  • Pediatric Neurology
  • Neuroradiology
  • Vascular Malformations

Background:

  • A rare diffuse arteriovenous malformation (AVM) is presented in an 11-year-old boy.
  • The patient had a 4-year history of transient ischemic attacks and left-sided weakness.

Observation:

  • Computed tomography (CT) revealed cord-like enhancement in the corpus callosum and pineal region.
  • Magnetic resonance (MR) imaging showed right hemisphere atrophy and signal voids.
  • Cerebral angiography identified a diffuse AVM fed by anterior and middle cerebral arteries.

Findings:

  • The AVM nidus was scattered, precluding surgical intervention.
  • Progressive neurological decline included worsening left hemiparesis and mental retardation.
  • Serial imaging demonstrated increased nidi, enlarged draining veins, and gyriform calcification.

Implications:

  • The AVM's diffuse nature and scattered nidi posed significant treatment challenges.
  • Gyriform calcification on CT mimicked Sturge-Weber syndrome, highlighting diagnostic considerations.
  • This case underscores the complex presentation and progression of rare pediatric AVMs.
