Syndrome Report

Cerebral hemiatrophy or Dyke-Davidoff-Masson syndrome is a condition characterized by seizures, facial asymmetry, contralateral hemiplegia or hemiparesis, and mental retardation. These findings are due to cerebral injury that may occur early in life or in utero. The radiological features are unilateral loss of cerebral volume and associated compensatory bone alterations in the calvarium, like thickening, hyperpneumatization of the paranasal sinuses and mastoid cells and elevation of the petrous ridge. The authors describe three cases. Classical findings of the syndrome are present in variable degrees according to the extent of the brain injury. Pathogenesis is commented.

Dyke-Davidoff-Masson Syndrome (DDMS), also known as cerebral hemiatrophy, is a rare clinical condition characterized by seizures, facial asymmetry, contralateral spastic hemiplegia or hemiparesis, with learning difficulties and behavioral changes. It is commonly diagnosed in presence of clinical feature associated radiological findings which include cerebral hemiatrophy with homolateral hypertrophy of the skull and sinuses. In this present case report a 12 year old teenager female patient was diagnosed as DDMS with recurrent generalized seizures, learning difficulties and right sided hemiparesis. Magnetic resonance imaging (MRI) of the brain showed hemiatrophy involving the left cerebral hemisphere and EEG showed generalized epileptiform discharged. An X-ray of the paranasal air sinuses was normal.DOI: http://dx.doi.org/10.3329/jssmc.v5i2.20768J Shaheed Suhrawardy Med Coll 2013;5(2):111-113

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.

Invasive craniocerebral aspergillosis, often encountered in an immunocompromised setting, is almost uniformly fatal despite radical surgical and medical management, and is frequently a necropsy finding. The authors report a unique, self-resolving clinical course of this aggressive infection in a 10-month-old infant. The infant was brought to the emergency services in altered sensorium with a 1-week history of left-sided hemiparesis, excessive irritability, and vomiting. An MRI study of the brain revealed multiple, heterogeneously enhancing lesions in the right cerebral hemisphere with mass effect. The largest lesion in the frontotemporal cortical and subcortical regions was decompressed on an emergent basis. Histopathological findings were suggestive of invasive aspergillosis, although there was no evidence of the infection in the lungs or paranasal sinuses. Computed tomography–guided aspiration of the remaining lesions and follow-up antifungal therapy were recommended. The parents, however, requested discharge without further treatment. The child was seen at a follow-up visit 3 years later without having received any antifungal treatment. Imaging showed resolution of the infection and features of Dyke-Davidoff-Masson syndrome (cerebral hemiatrophy). This report of invasive cerebral aspergillosis resolving without medical therapy is the first of its kind. Its clinicoradiological aspects are discussed in light of previously reported cases.
