Article Synopsis
- Computed tomography (CT) is the primary method for diagnosing mycotic aneurysms, and this study aimed to classify their CT findings and evaluate their predictive value for patient outcomes.
- Over 21 years, 40 patients who underwent surgery for mycotic aneurysms were analyzed, categorizing CT appearances into four grades based on severity.
- The study found a significant link between higher CT grades and poorer surgical outcomes, indicating that this grading system could effectively assess patient risk and guide treatment decisions.
Background: Spontaneous arterial bleeding in patients with type 1 neurofibromatosis is uncommon. It can be fatal if not recognized and treated in a timely manner.
Objectives: Diagnose and treat an uncommon complication in type 1 neurofibromatosis.
Purpose: To evaluate multidetector computed tomographic (CT) images to investigate the prevalence, morphology, natural course, and prognostic effect of intramural blood pools (IBPs) in patients with acute intramural hematoma (IMH).
Materials And Methods: Institutional review board approval and written informed consent were obtained. Sixty-five patients (41 men; mean age, 65.
A 48-year-old woman presented with a growing palpable mass at the left frontal area. The imaging studies and histopathological examination of the mass was consistent with dural-based Rosai-Dorfman disease with unusual transcranial extension. We reported this case not only because of its rarity, but also because of the infiltrative pattern.

Materials And Methods: During a 48-month period, 28 women (age range, 38-76 years) were referred to our department for retrograde exchange of a ureteral stent. The causes of urinary obstruction were tumor compression in 26 patients and benign fibrotic stricture in two patients.
Objective: Coronary artery calcification (CAC) is frequently detected on low-dose ungated MDCT performed for lung cancer screening. We aimed to determine the concordance of CAC scores on low-dose ungated and regular-dose ECG-gated MDCT.
Subjects And Methods: The subjects were 513 patients consecutively registered for health screening and undergoing both low-dose ungated (120 kVp, 20 mAs) and regular-dose ECG-gated MDCT (120 kVp, 150 mAs, retrospective ECG gating).
