Lissencephaly is a rare malformation of the human brain manifest by a smooth cerebral surface. It is usually associated with other brain anomalies. The computed tomographic appearance in nine patients with lissencephaly, representing several separate types and syndromes, is reported. Common manifestations include a smooth cerebral surface and absent opercula that may lend a figure-eight appeara...

PURPOSE To describe symptomatic pulmonary emboli from brain arteriovenous malformation embolization with liquid acrylates and to analyze the reasons for these complications and describe preventive techniques. METHODS The clinical records of 182 patients embolized with acrylate glue since 1978 for treatment of brain AVMs were searched for evidence of symptomatic pulmonary complications. Origin...

Vein of Galen aneurysmal malformation (VGAM) is a rare congenital malformation, accounting for less than 1% of cerebrovascular abnormalities. The majority of reported cases have been associated with congestive heart failure (CHF) in the neonatal period. Herein, we present a case of VGAM, diagnosed at 37 weeks of gestation during the intrauterine life Case report: A full-term female newborn pre...

A Chiari malformation Type I may remain asymptomatic until the patient has reached adulthood and acute presentation of symptoms occurs. In several clinical and experimental studies it has been shown that essential hypertension is associated with vascular compression of the brainstem, particularly of the rostral ventrolateral medulla oblongata. Nevertheless, two cases of Chiari malformation and ...

In this report, we describe a case of multiple brain abscesses associated with diffuse congenital pulmonary arteriovenous malformations (PAVM). Although the cases of brain abscesses associated with congenital PAVM are very rare, the brain abscess could be an initial clinical manifestation in asymptomatic PAVM as in the case presented in this report. PAVM may contribute to the development of a b...

The Abernethy malformation is a rare congenital malformation defined by the presence of an extrahepatic portosystemic shunt. Although most patients are asymptomatic, clinical encephalopathy is present in 15% of cases. We present a patient with type 2 Abernethy malformation, hyperammonemia, and encephalopathy. Shunt closure was performed successfully using interventional angiography; however, hy...

Holoprosencephaly is a malformation of the brain due to a disturbance of the growth of the prosencephalon during the third cerebral vesicle phase of early fetal life. It is an anomaly of the prosencephalon with a single ventricle associated with malformation of the telencephalon and diencephalon. According to the degree of the malformation, this anomalad is classified into three types (DeMyer, ...
