Review Case Reports
Carotid-anterior cerebral artery anastomosis: MR angiographic features and literature review.
Carotid-anterior cerebral artery anastomosis is a rare anomaly of the anterior part of the circle of Willis. We report here magnetic resonance (MR) angiographic findings in 2 patients with this anomaly. ⋯ Thirty anomalous arteries were found in the 27 patients (R/L/bilateral=22/2/3). The reason for the right-sided predominance is unknown.

Subependymomas are rare, slow-growing, benign intraventricular tumors which occur commonly in the fourth or lateral ventricle. They usually occur in elderly men and often are asymptomatic and discovered incidentally. We report a case of a 6-year-old girl with a symptomatic subependymoma in the third ventricle with MR imaging.

The purpose of this study was to characterize the diagnostic performance of a regimen of CT screening for lung cancer. ⋯ The performance of the ELCAP regimen is quite satisfactory in avoiding over many positive results of the initial CT, and it produces highly promising diagnostic results as for the attainment of cure by early intervention.
