Porencephalic Cyst

Porencephalic cyst is a rare entity in adults with limited cases reported so far. It is usually congenital and seen in neonates. Here, we report a 25-year-old male who presented with post-ictal confusion following an episode of sudden onset of generalised tonic clonic seizure. He was diagnosed to have large cerebrospinal fluid (CSF) density cystic lesion in the right parieto-occipital region communicating with occipital horn on right side side of porencephaly. Porencephaly is an uncommon congenital disorder that occurs due to cystic degeneration and encephalomalacia leading to porencephalic cyst formation.1 They are considered to occur most commonly from focal encephalomalacia due to a localised cerebral insult during early gestation, 2 while the other aetiologies include trauma, infection, antenatal intraparenchymal haemorrhage and perinatal cerebral ischemia.3 If the insult occurs in late third trimester it can lead to gliosis. Porencephalic cysts are typically lined by white matter of brain parenchyma.2 They differ widely in their location and size while the clinical manifestations and presentations range from being asymptomatic to extremely impaired mental function. Generally, the signs and symptoms of porencephaly become apparent in the first year of life. The earliest manifestation being spasticity and seizures. As the age increases there is a delay in development of milestones presenting as language impairment, disability in intellect and motor deficits. Clinically head circumference measurement varies from being normal or small to an enlarged head in cases of synechiae formation that creates a one-way valve effect leading to progressive enlargement of the cyst and expansion of skull or there may be hydrocephalus.4 Radiologically the diagnosis depends on demonstrating a well-defined CSF-filled space occupying lesion lined by white matter and communicating with ventricles on computed tomography (CT) scan or magnetic resonance imaging (MRI) of brain. The prognosis of porencephaly depends on the location and extent of the cyst.5 If the cyst is very large it can cause mass effect in the form of scalloping of adjacent bone, buckling of brain parenchyma, midline shift to contra lateral side and hydrocephalus. On MRI, brain cyst appears well defined and lined by white matter with or without gliosis. Cerebrospinal fluid is the content which is shown as hypointense on T1 and hyperintense on T2.
