Anterior tibial translocation sign

The anterior tibial translocation sign or anterior drawer sign (a.k.a. anterior translation of tibia) is seen in cases of complete rupture of the anterior cruciate ligament, and refers to anterior translocation (anterior tibial subluxation) of the tibia relative to the femur of more than 7 mm 1. 

Ehlers-Danlos syndrome

Ehlers-Danlos syndrome comprises a heterogeneous group of collagen disorders (hereditary connective tissue disease). Epidemiology There is a recognised male predominance. Clinical presentation Clinically manifests by skin hyperelasticity and fragility, joint hypermobility and blood vessel fr...

Struma ovarii tumour

Struma ovarii tumour is a subtype of an ovarian teratoma and is composed entirely or predominantly of thyroid tissue and containing variable-sized follicles with colloid material. Epidemiology It accounts for 0.3-1% of all ovarian tumours and ~3% of all mature cystic teratomas 1. Clinical pre...

Lung parenchyma

Lung parenchyma is the portion of the lung involved in gas transfer - the alveoli, alveolar ducts and respiratory bronchioles. However, some authors include other structures and tissues within the definition. Related pathology parenchymal lung disease See also parenchyma


In anatomy, parenchyma refers to the functional part of an organ in the body. This is in contrast to the stroma or interstitium, which refers to the structural tissue of organs, such as the connective tissues. Embryologically, the majority of organ parenchyma develops from the ectoderm or endod...

Pulmonary opacification

Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is. The pat...

Parenchymal lung disease

Parenchymal lung diseases can broadly be divided into those that create an abnormal increase in density on a chest radiograph and those that cause increased lucency.  The attenuation of any tissue on a radiograph is related to its density and in the lung, this is determined by the ratio of gas ...

Borderline ovarian serous cystadenoma

Borderline ovarian serous cystadenomas lie in the intermediate range in the spectrum of ovarian serous tumours and represent approximately 15% of all serous tumours. Epidemiology They present at a younger age group 1-2 than the more malignant serous cystadenocarcinomas with a peak age of prese...

Coal workers' pneumoconiosis
