The common congenital lung malformations have traditionally been divided into separate pathological entities such as pulmonary airway malformations, cystic adenomatoid malformations, congenital lobar emphysema, intra or extra pulmonary sequestrations, bronchogenic and foregut cysts. Some may produce respiratory compromise immediately after birth or even in utero. The management of such life thr...
Ductal plate malformations are a heterogenous group of congenital fibrocystic liver diseases resulting from insult to the ductal plate at various stages of embryogenesis. As a result various biliary malformations, cysts, hamartomas and congenital hepatic fibrosis may be seen. We present a radiological pictorial of ductal plate malformations, accurate diagnosis of which is important for clinical...
In the female, Müllerian ducts will develop to form the uterine tubes, uterus, cervix, and the upper one-third of the vagina; in the male, they are lost. This abnormal development can lead to uterine malformations resulting from aplasia of a part of Müllerian duct. Morphological abnormalities can vary from insufficient fission of tissues causing bicornuate uterus, double uterus or preserved ute...
Arteriovenous malformations of the brain are congenital vascular lesions that affect 0.01-0.50% of the population, and are generally present in patients aged 20-40 years. The usual clinical presentations are haemorrhage, seizures, progressive neurological deficit, or headache. Results of natural history studies have shown a yearly haemorrhage rate of 1-4%. Frequency of rebleeding has increased ...
477 Vascular anomalies (birthmarks) are commonly encountered lesions and vary from tiny skin discolorations to large, devastating lesions requiring invasive interventions (Table 1).1 These lesions can involve any part of the body, but the lower extremities, particularly the foot and ankle regions, are commonly affected. A vascular anomaly in the foot or ankle usually requires treatment because ...
Some are born monsters, some achieve monstrosity; others have monsters thrust upon them! I put myself in the last category. When I first went to work at Southmead Hospital some twelve years ago I was no more or less interested in monsters and congenital malformations than in a great many other things. I soon found however, that this problem was indeed thrust upon me. Monsters and malformations ...
In this country today if a child survives the first 4 weeks after birth he has a very good chance of 70 years of life, but to attain this he still has to negotiate the hazardous perinatal period. The perinatal mortality survey for England, Scotland and Wales showed that the highest single cause of first week deaths is congenital malformation, constituting nearly 25 per cent of deaths in March 1...
Intraosseous venous malformations are rare lesions in the facial bones often presenting incidentally on imaging, and accounting for 0.5% to 1% of all osseous tumors. Physicians presented with a diagnostic challenge differentiating intraosseous from bony mandible midface. This is due rarity malformations, which have an asymptomatic course, potential significant intraoperative blood loss. We repo...
Developmental venous anomaly (DVA)/ Cerebral Venous Angioma is the most common type of cerebral vascular malformations, mostly an incidental benign finding. But there are documented associated complications like parenchymal signal abnormalities, thrombosis, cavernous malformations and atrophy.
 In this report, we present a unique case DVA with cortical changes mimicking Glioma. Altered hae...
