Lobar and segmental liver atrophy associated with hilar cholangiocarcinoma and the impact of hilar biliary anatomical variants: a pictorial essay
The radiological features of lobar and segmental liver atrophy and compensatory hypertrophy associated with biliary obstruction are important to recognise for diagnostic and therapeutic reasons. Atrophied lobes/segments reduce in volume and usually contain crowded dilated bile ducts extending close to the liver surface. There is often a “step” in the liver contour between the atrophied and non-atrophied parts. Hypertrophied right lobe or segments enlarge and show a prominently convex or “bulbous” visceral surface. The atrophied liver parenchyma may show lower attenuation on pre-contrast computed tomography (CT) and CT intravenous cholangiography (CT-IVC) and lower signal intensity on T1-weighted magnetic resonance imaging (MRI). Hilar biliary anatomical variants can have an impact on the patterns of lobar/segmental atrophy, as the cause of obstruction (e.g. cholangiocarcinoma) often commences in one branch, leading to atrophy in that drainage region before progressing to complete biliary obstruction and jaundice. Such variants are common and can result in unusual but explainable patterns of atrophy and hypertrophy. Examples of changes seen with and without hilar variants are presented that illustrate the radiological features of atrophy/hypertrophy

Internal thoracic vein draining into the extrapericardial part of the superior vena cava: a case report
The internal thoracic veins are venae comitantes of each internal thoracic artery draining the territory supplied by it and usually unite opposite the third costal cartilage. This single vein enters the corresponding brachiocephalic vein. We present a variation of right internal mammary vein draining into superior vena cava in a 45-year-old male cadaver. Likely development and clinical significance of the vein are discussed.<br>As veias torácicas internas sĂŁo veias comitantes de cada artĂ©ria torácica interna drenando o territĂłrio suprido por ela e geralmente se unem em frente Ă terceira cartilagem costal. Esta Ăşnica veia entra na veia braquicefálica correspondente. Apresentamos uma variação da veia mamária interna direita drenando para a veia cava superior em um cadáver masculino de 45 anos. O provável desenvolvimento e a significância clĂnica da veia sĂŁo discutidos
