The preoperative MRI demonstrated a solitary inhomogeneous enhanced intra- and
extracranial lesion (5.

Two-depth TCD simultaneously measures blood flow parameters in the intracranial and
extracranial segments of the ophthalmic artery and compares that parameters in order to identify the balance aICP=aPe.
McWhorter et al[2] reported a case of an
extracranial meningioma that presented as a lytic parietal lesion.
7%; number needed to harm [NNH] = 143) and more

It mainly affects
extracranial and unilateral arteries, which is consistent with the radiation field.
Our present study consists of evaluating
extracranial carotid artery system in 50 patients with color Doppler and contrast enhanced Magnetic resonance Angiography in the population presented with stroke.
The cerebrospinal venous system has been the focus of many studies in the last few years, because of the hypothesized involvement of insufficient
extracranial venous drainage in central nervous system disorders such as multiple sclerosis, normal-pressure hydrocephalus, and transient monocular blindness [1-4].
They describe its history; delivery systems; patient positioning and immobilization, including for cranial and
extracranial treatment; treatment planning and dosimetry; and new directions, including radiation biology, and clinical outcomes using stereotactic radiation therapy and stereotactic radiosurgery.
A PSS is an emissary vein of the posterior fossa that courses along the petrosquamosal junction, connecting the sigmoid or transverse sinus with the
extracranial venous system.
They cover the basic and physical principles of Doppler and color Doppler ultrasound; ultrasound examination technique, documentation, and terminology; sonographic anatomy and pathology, including the neck lymph nodes,
extracranial nerves, floor of the mouth and oropharynx, salivary glands, facial soft tissues, paranasal sinuses and midface, and larynx and hypopharynx; and advanced image processing methods.
