Calcifying fibrous (pseudo) tumour (CFP) is an uncommon and distinct pathological entity, which is usually occurring in the soft tissue of the extremities, trunk, axilla, pleura, mediastinum and peritoneum. We report a case of CFP of the adrenal gland. A 29-years-old previously healthy woman complained the left lumbago. A solid mass was found on computed tomography on the left adrenal gland. There were no abnormalities in physical examination and laboratory studies. Only urinary noradrenalines and dopamines levels were slightly high. Laparoscopic left adrenalectomy was performed. Pathological findings of the left adrenal tumor showed dense hyalinized fibrous tissue containing bland spindle-shaped cells, calcifications, and lymphoplasmacytic infiltrate. Our case seems to be the first case of CFP to be published in the Japanese literature.

Background: Atherosclerosis is a lipid-driven, systemic immune-inflammatory disease characterized by the accumulation of plaque within the arterial walls. Plaque regression can occur following appropriate treatment interventions. Optical coherence tomography (OCT), a high-resolution imaging modality, is frequently employed to assess plaque morphology.

Background: Preliminary research indicates that higher iron levels are associated with worse outcomes in patients with coronary artery disease.
Aims: The study aimed to investigate the relationship between iron levels and the type and composition of coronary plaques.
Methods: In patients with ≥1 coronary stenosis ≥50% on computed tomography angiography, iron levels, presence of high-risk plaque features, such as low-attenuation plaque (LAP), napkin-ring sign, positive remodeling, and spotty calcium, as well as type and plaque composition (calcified/fibrous/fibro-fatty/necrotic core) were evaluated.

Background: Stroke is a leading cause of death and disability worldwide, affecting millions annually. Accurate etiological diagnosis is critical for the effective treatment and prevention of recurrent strokes. Traditional luminal imaging techniques like computed tomography (CT) and magnetic resonance angiography (MRA) provide limited information, focusing solely on vessel lumen characteristics.

Objective: The rupture of vulnerable plaques in the carotid artery is a leading cause of strokes. While magnetic resonance imaging (MRI) is the standard for quantifying plaque composition, its high costs and lengthy procedure times limit large-scale use. Compound ultrasound strain imaging (CUSI) ultrasound offers a non-invasively alternative by assessing tissue deformation/strain within the arterial wall.
