The authors describe the magnetic resonance (MR) findings in seven patients who developed severe cerebellar symptoms and atrophy of the contralateral red nucleus following removal of unilateral neoplasms in the deep nuclei of the cerebellum. For most patients, pre- and postoperative spin-echo MR images were obtained with long repetition times (TRs) at 1.5… (More)
Our aim was to demonstrate the orifice of intracranial aneurysms by magnetic resonance angiography (MRA). The aneurysmal orifice is that part of its lumen that communicates with the parent vessel. We studied 12 patients with 17 intracranial aneurysms using three-dimensional display (3DD) MRA; 15 of the aneurysms had previously been shown by digital… (More)
The authors present the case of a 52-year-old female patient with a 6-year history of intractable paroxysmal otalgia. Preoperative magnetic resonance (MR) angiography demonstrated an anterior inferior cerebellar artery loop compressing the intermediate nerve in the seventh/eighth cranial nerve complex inside the internal auditory canal. The pain resolved… (More)
Background. Aneurysms of the extracranial vertebral artery are rare and can provide a diagnostic and therapeutic challenge. Methods. We reviewed the clinical history of a patient presenting with cervical radiculopathy, who harboured an extracranial vertebral artery aneurysm eroding the cervical spine. Results. CT Angiography and MR Angiography set the… (More)
We present the case of a young male with severe head injury, cervico-thoracic fractures, and an initially unrecognized brainstem infarct due to unilateral dissection of vertebral artery, who made an unusually excellent recovery. This report stresses the importance of prompt clinico-imaging diagnosis and prophylactic anticoagulant treatment in such cases.
