Dual Supply of Left Anterior Descending Coronary Artery on Coronary Computed Tomographic Angiography Not Recognized on Previous Cardiac Catheterizations.

A dual left anterior descending (LAD) artery is an infrequent anomaly of the coronary circulation with rare variations that may cause symptoms. We report a 60-year-old man who underwent multiple percutaneous cardiac catheterizations with stent placements and presented with recurrent angina pectoris. Coronary computed tomographic angiography demonstrated a dual LAD with the long and short LADs originating from the right coronary artery and the left main coronary artery, respectively.

High-resolution CT findings suggest a developmental abnormality underlying superior canal dehiscence syndrome.

Objective: Patients with superior canal dehiscence (SCD) syndrome experience vertigo and oscillopsia with loud sounds and/or stimuli that result in changes in middle ear or intracranial pressure. Findings on temporal bone CT were analyzed to determine if a developmental abnormality is associated with the syndrome.

Material And Methods: Temporal bone CT scans [0.

CT evaluation of bone dehiscence of the superior semicircular canal as a cause of sound- and/or pressure-induced vertigo.

Purpose: To describe the computed tomographic (CT) findings at different collimation widths associated with superior semicircular canal (SSC) dehiscence syndrome and to determine the frequency of these findings in a control population.

Materials And Methods: Temporal bone CT scans with 1.0-mm and/or 0.

Aspiration biopsy in a case of apocrine adenocarcinoma with foam cells (myoblastomatoid or histiocytoid adenocarcinoma).

We found only one report of a case of apocrine adenocarcinoma with foamy cells diagnosed by aspiration biopsy. Herein, we describe a second case with cytologic, histologic, and immunohistochemical findings and discuss the differential diagnosis of foamy cells on aspiration smears obtained from mammary nodules.

The Use of Stereotaxic Core Biopsy and Stereotaxic Aspiration Biopsy as Diagnostic Tools in the Evaluation of Mammary Calcification.

We compared stereotaxic fine needle aspiration biopsy (SFNA) with stereotaxic core needle biopsy (SCB) in the evaluation of radiographically clustered mammary microcalcification, a common finding at screening mammography. Over a 4-year period, 181 specimens were obtained from 175 patients who underwent both SFNA and SCB of clustered microcalcification. Aspiration and core biopsies were performed by radiologists at a community-based diagnostic radiology facility.
