چکیده

Vascular compression as the cause of aqueductal stenosis is rare. In a 16-year-old girl with hydrocephalus, MR imaging provided evidence of aqueductal stenosis caused by a venous angioma in the tectum and midbrain. This indicates the usefulness of MR imaging for the evaluation of obstructive hydrocephalus.

Treatment differences in cases with venous angioma.

Venous angiomas were found to be the most common cerebral vascular malformations, composing 63% of such lesions in two autopsy series. Annual bleeding risk associated with venous angiomas is about 0.22 % per year. Venous angiomas are generally silent lesions because of their dynamic features, and are low flow and low pressure vascular structures draining normal brain tissue. An angioma rarely c...

Midbrain venous angioma with obstructive hydrocephalus.

A rare case of a mid brain venous angioma with obstructive hydrocephalus is described. A dilated draining vein from the lesion in the aqueduct as the cause of the hydrocephalus is highlighted, and interesting features of the pathology of venous angiomas and associated cavernous hemangioma are described. The management of this interesting condition is discussed.

MR Elastography Can Be Used to Measure Brain Stiffness Changes as a Result of Altered Cranial Venous Drainage During Jugular Compression.

BACKGROUND AND PURPOSE Compressing the internal jugular veins can reverse ventriculomegaly in the syndrome of inappropriately low pressure acute hydrocephalus, and it has been suggested that this works by "stiffening" the brain tissue. Jugular compression may also alter blood and CSF flow in other conditions. We aimed to understand the effect of jugular compression on brain tissue stiffness and...

Analysis of cerebrospinal fluid flow waveforms with gated phase-contrast MR velocity measurements.

PURPOSE To analyze the characteristics of normal cerebrospinal fluid (CSF) flow waveforms and to relate them to the arterial input and venous output flow waveforms in healthy volunteers. METHODS Cine phase-contrast MR was obtained in 17 volunteers. The temporal velocity information from the cervical pericord CSF spaces, basal cisterns, and aqueduct, as well as the internal carotid and vertebr...

Simultaneous occurrence of developmental venous anomalies and cavernous angiomas.

PURPOSE To study the clinical and radiologic findings in 15 patients presenting with both developmental venous anomalies and cavernous angiomas and to determine which lesions caused the acute clinical symptoms. METHODS Lesions were infratentorial in 7 patients and supratentorial in 7 other patients. In one patient the developmental venous anomaly was infratentorial and the cavernous angioma s...
