Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

5.4K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Area of Science:

  • Neurology
  • Immunology
  • Pathology

Background:

  • Primary central nervous system angiitis (PCNSA) is a rare idiopathic vasculitis affecting only the central nervous system.
  • It presents with diverse clinical manifestations that can mimic other vasculopathies, complicating diagnosis.

Observation:

  • A case of a 24-year-old female with non-specific neurological complaints over time is presented.
  • Diagnostic challenges were encountered before a tissue biopsy confirmed PCNSA.

Findings:

  • Despite increasing reports, PCNSA pathogenesis remains unclear.
  • Diagnosis is challenging due to lack of universal criteria and definitive diagnostic tests (lab or imaging).

Implications:

  • Awareness of PCNSA differentials is vital for clinicians to prevent misdiagnosis.
  • Timely and accurate diagnosis is essential for appropriate patient management.
