Underdiagnosis of umbilical hernias in CT scans in a multicenter study - the radiologically neglected pathology and its surgical implications.

Purpose: Umbilical hernias (UH) have a higher prevalence than previously considered. With the high workload radiologists must endure, UH can be missed when interpreting a computed tomography scan (CT). The clinical implications of its misdiagnosis are yet to be determined.

Avoiding iatrogenic injuries to the vertebral artery: A morphometric study of the vertebral artery-free dissection area.

Objective: To determine the area of a safety window that excludes the vertebral artery for the safe access of the occipital condyle screws during occipitocervical fixation.

Methods: This study included 138 cervical computed tomography angiograms. Six measurements per side were made in each imaging study.

Gastric Metastasis of Prostate Cancer as an Unusual Presentation Using 68Ga-Prostate-Specific Membrane Antigen PET/CT.

A 79-year-old man with prostate cancer underwent Ga prostate-specific membrane antigen (Ga-PSMA) dual-time-point PET/CT scan to evaluate tumor activity due to early satiety, unquantified weight loss, and elevation of prostate-specific antigen (PSA), demonstrating thickening of the gastric wall with intense tracer uptake. The immunohistochemistry of gastric biopsy showed CDX2 and CK20: negative; CK7, focal positive; PSA, positive, which confirmed metastatic disease. Metastatic disease was also found in bones, right lung, and retroperitoneal and pelvic lymphadenopathies.
