Unilateral agenesis of the internal carotid artery (lCA) is a very rare anomaly. Generally, when the ICA is congenitally absent, blood is carried to the affected side through the circle of Willis by the basilar artery and the opposite ICA. We report a case of unilateral agenesis of the ICA in which the affected hemisphere was supplied by an anomalous artery(More)
Percutaneous retrogasserian glycerol rhizolysis (PRGR) became a diffuse and valuable method for treatment of trigeminal neuralgia, following its introduction by Hakanson in 1981. Its main advantages are: a) mild postoperative facial sensory loss, b) simplification of the technique, c) reduction of costs. Our results in a series of 191 patients treated(More)
A case of calcified chronic subdural hematoma was presented. This patient was a 51-year-old man, who had a dizzy spell with headache and vomiting. He was examined by MR study as well as CT scan. The operation was performed and the calcified subdural hematoma was removed safely. MR study is very useful for the preoperative evaluation.
Waldenström Macroglobulinemia (WM) involves the Central Nervous System in about 10% of the affected patients, but only occasionally related clinical and histopathological changes have been considered. Most of the published papers focus on leptomeningeal lymphoplasmacytic infiltrates, even though the damage to the CNS results in a more variegated scenario.(More)
Among posterior fossa tumors, schwannomas arising from glossopharyngeal nerve are rare; only about 30 cases of glossopharyngeal neuroma have been described. Though a typical 'jugular foramen syndrome' has been described for tumors of this region, the clinical onset may often closely resemble that of acoustic neuromas thus misleading the diagnosis. Because(More)
Subdural interhemispheric hematomas (ISH), though not really rare, are quite an uncommon complication of head traumas. This condition is more frequent in childhood, where it is generally considered as a part of a more complex syndrome, called 'Shaken Children Syndrome', usually pointing out child abuse. Although a head injury is very often considered the(More)
