Does computed tomography-derived volumometry and densitometry of psoas muscle really correlate with complications in rectal cancer patients after elective surgery?

Objectives: Although sarcopenia is recognized as one of the risk factors for increased morbidity after resection for colorectal cancer, the question of the most appropriate way to identify and quantify it is still unresolved.

Material And Methods: This is a retrospective unicentric study following patients undergoing elective resection of the rectum for carcinoma with available staging computed tomography (CT) of the trunk. Psoas muscle density (PMD) and its area relative to patient height psoas muscle index (PMI) at the level of inferior vertebral end plate of third lumbar vertebra (L3) were assessed using an initial staging CT scan of the trunk.

Asymptomatic Bochdalek's Hernia in an Adult: A Case Report.

Bochdalek's hernia is the most common congenital malformation of the diaphragm with a defect in its posterolateral part. Its clinical manifestation in adulthood is rare. It is often an incidental finding, and its diagnosis may be challenging.

Percutaneous CT-guided Biopsy of Focal Liver Lesions - Long- term Experience with more than 300 Procedures.

Background And Aims: Despite the undeniable ongoing development of cross-sectional imaging methods, not all focal liver lesions (FLLs) have a typical pattern. An image-guided biopsy using a percutaneous approach might safely provide a final histological diagnosis of the FLLs. We aimed to evaluate the accuracy, efficiency, complication rate, technical features, and relationships between the followed parameters of computed tomography (CT)-guided percutaneous biopsies of FLLs using a retrospective approach.

Emergence of a lymphoma imitating an infectious infiltration surrounding the infrarenal aorta after EVAR.

Primary retroperitoneal localization of non-Hodgkin's lymphoma is rare but should be considered, even if the circumstances surrounding its emergence point to other direction. We present a case of an appearance of periaortic infiltration after successful endovascular treatment which turned out to be of malignant origin.
