The gross impression of this brain, which belonged to... Continue Reading →

Leptomeningitis and Perivascular Spread

Many blood vessels that supply the brain and spinal cord initially run within the covering layers on the external surface, called the leptomeninges (also known as the pia-arachnoid), before plunging into the deeper neural tissue. As the vessel transitions from the outer layers into deeper tissue, the perivascular space immediately surrounding the vessel, called Virchow-Robin space, may provide a conduit for infectious/inflammatory processes. ...
