The extrapleural fat sign on postmortem computed tomography may differentiate acute from chronic extrapleural hematomas

Extrapleural fat sign.

Explanation: Extrapleural fat, endothoracic fascia, and the innermost layers of intercostal muscle are superficial to the parietal pleura. Extrapleural fat is usually seen as a 1mm thick low attenution line on chest CT and is almost imperceptible in normal individuals.2 It may be thicker in obese patients. Accumulation of blood in the extrapleural space results in an extrapleural hematoma (EPH)...

Extrapleural locating method in computed tomography-guided needle biopsies of 1,106 lung lesions.

Transthoracic needle biopsy is considered to be safe and effective for the diagnosis of focal lung lesions. The aim of the present study was to evaluate factors affecting the accuracy and safety of automated cutting needle lung biopsy (ACNB) using a new extrapleural locating (EPL) method. Computed tomography (CT)-guided needle biopsies were performed on 1,065 patients between March 2005 and May...

Haemorrhage after extrapleural pneumonolysis.

Moderate or massive haemorrhage into the extrapleural space within a few days of the performance of an extrapleural pneumonolysis occurs in from 5 per cent to 20 per cent of cases. It may give rise to few symptoms, or be severe enough to cause alarming collapse of the patient and justify, if not demand, immediate transfusion. Apart from the immediate and more alarming physiological disturbances...

Video-atlas of extrapleural pneumonectomy.

This is a step-by-step video demonstration of a left extrapleural pneumonectomy for malignant pleural mesothelioma, including thoracotomy incision, extrapleural mobilization of tumor, resection of diaphragm, mediastinal nodal dissection and division of hilar vessels followed by reconstruction of diaphragm and closure of the thoracotomy.
