Porencephaly

The Porencephaly ( from Greek πόρος, Poros, " passage " and κεφαλή, kephale in AltGr. Debate, "head" ) is, according to current knowledge, a congenital or acquired peripartal, attributable to local circulatory disturbances brain malformation. As a pseudo - porencephaly it can also be caused by bleeding in the brain or trauma. This leads to necrosis in cortex and medulla of the immature cerebrum and subsequent gap formation in the brain substance in the form of crater-shaped recoveries smooth surface of the brain ( Pori - Siegmund ). These can be combined (outer Porencephaly ) or in depth with the ventricular system (inner Porencephaly ) with the externally located subarachnoid space.

At emergence from Pori to maturation of the marrow in the second year they may have in addition to organization operations fat granules and pigment cells. In adults below remains the Pori - formation due to the insufficient supply of the outer cortical layers via the cerebrospinal fluid.

The Parenchymverluste can - depending on the location - remain asymptomatic or cause seizures, paralysis and disorders of the extrapyramidal system (EPS).
