Patients with symptoms and signs of central nervous system dysfunction frequently present to outpatient clinics and emergency departments. Disturbances of consciousness and cognition, headache, vertigo, dizziness or light-headedness, seizures, hemiparesis or hemisensory deficits, and other motor dysfunctions may be due to diseases of internal medicine in up to 50% of cases apart from exclusively neurological diseases. A neurological syndrome oriented analysis of each clinical case allows the exact differential diagnosis of the causes of the disease. A combined approach of internal medicine physicians and neurologists is often warranted.

Posttransplantation lymphoproliferative disorder involving the central nervous system is a rare and serious complication associated with solid organ transplantation. We report a liver transplant recipient who noticed unbalance, dizziness, and headache 30 months after transplantation. Magnetic resonance imaging (MRI) showed a space-occupying lesion in the corpus callosum and adjacent parenchyma of the left hemisphere. In the following month, the neurological symptoms and the MRI findings regressed without any treatment. Four months later the patient developed a left-sided hemiparesis. MRI now revealed a considerable increase of the known lesion and new lesions in other locations. Stereotactic biopsy showed a B-cell non-Hodgkin lymphoma of high malignancy. A spontaneous regression of cerebral lymphoma is possible, even in immunosuppressed patients. Hence, this diagnosis must not be dismissed if there is spontaneous regression of a lesion in the MRI or an amelioration of the clinical symptoms. Owing to the high mortality rate associated with this disease, prompt pathologic diagnosis is required to initiate appropriate therapy.

Remote cerebellar hemorrhage is a usual complication after supratentorial craniotomy. Especially, only several cases have been reported regarding the occurrence of remote cerebellar hemorrhage after burr hole drainage for the treatment of chronic subdural hematoma (CSDH). In this paper, we present an elder patient with this rare postoperative complication. A 73-year-old man presented with dysarthria and right hemiparesis. Computed tomography (CT) demonstrated a left chronic subdural hematoma. Hematoma drainage through a single burr hole was perfomed. About 3 hours after the surgery, the patient became restless and presented nausea and dizziness with a relatively large amount of drainage of hematoma. CT revealed resolution of the subdural hematoma and bilateral cerebellar hemorrhage appearing as "zebra sign". Magnetic resonance angiography and 3D-CT angiography showed the normal structure of posterior circulation in both the arterial and venous phases. The remote cerebellar hemorrhage was suspected to have happened as a result of overdrainage of hematoma. Finally, he was discharged without any neurological deficits. Although remote cerebellar hemorrhage after drainage through a burr hole for the treatment of chronic subdural hematoma is a rare complication, it is necessary to be aware of the possibility of such a complication after supratentorial surgery.

The incidence of brain abscess remains high, despite the development of novel antibiotics. Vancomycin or carbapenems, which are third-generation cephems, are recommended as standard therapy for bacterial meningitis or brain abscess. The effectiveness of the high-dose meropenem therapy on brain abscess has occasionally been reported. We experienced 2 consecutive cases of brain abscess in adults. The first patient was a 67-year-old man with diplopia, dizziness, and dysesthesia on the left upper and lower extremities. Images of T1-weighted magnetic resonance imaging (MRI) with contrast medium and diffusion-weighted MRI showed a ring enhancing cystic lesion and a high intensity lesion, respectively, in the right pons. The second patient was a 37-year-old man who complained of right hemiparesis. MRI revealed a ring-enhancing cystic mass in the left thalamus. On the basis of MRI findings, patients were diagnosed with brain abscess and were given high-dose meropenem (6g/day) continuously for 2 months. The abscess resolved completely after treatment with meropenem administered intravenously. Further, neurological deficits caused by abscess successfully improved. High-dose meropenem therapy should be considered as an effective treatment for brain abscess, even in the brain stem and basal ganglia, where it is quite difficult to achieve surgical access.

A case of anaplastic oligodendroglioma with femoral metastasis is presented in a 37-year old male with a 2-year history of progressive headaches and dizziness associated with a 2-month history of epilepsy and right hemiparesis. Magnetic resonance imaging (MRI) demonstrated a solid temporoparietal tumour and the patient underwent a left temporal craniotomy and subtotal resection followed by limited-field radiation therapy. The pathological diagnosis was anaplastic oligodendroglioma. The patient presented with left hip pain 3 years later. Radiography and computed tomography demonstrated osteosclerosis of the left proximal femur, and MRI revealed an intramedullary metastatic lesion. Total body (99m)Tc-methylene diphosphonate bone scan showed hyperactivity in the lesion and open biopsy confirmed it was a metastasis from the cerebral oligodendroglioma. The patient was treated with temozolomide and, to date, there is no sign of recurrence or progression in either the brain or the femur. Seven previously reported cases of extracranial skeletal metastasis from anaplastic oligodendroglioma are reviewed. Co-deletion of chromosome arms 1p and 19q and O(6)-methylguanine DNA methyltransferase status remain the most important prognostic and predictive markers.

The best surgical treatment of cerebral arachnoid cysts is yet to be established. Treatment options are shunting, endoscopic fenestration or microsurgical fenestration through craniotomy.Data from 69 patients with cerebral arachnoid cysts treated in our institution between 1997 and 2007 were reviewed.Cysts were located infratentorially in 20% (n = 14) and supratentorially in 80% (n = 55); of these 73% (n = 40) were in the middle cranial fossa. Mean cyst size was 61 mm (range 15-100 mm). The most common symptoms were headache (51%), dizziness (26%), cranial nerve dysfunction (23%), seizure (22%), nausea and vomiting (18%), and hemiparesis (13%). Surgery was performed in 83% (n = 57). First-line treatments were microsurgical fenestration (n = 30), endoscopic fenestration (n = 15), and cystoperitoneal/ventriculoperitoneal shunting (n = 11). More than one intervention was needed in 42% (n = 24). A particularly high rate of relapse (73%) was observed after endoscopic fenestration, following which 11 patients were admitted for reoperation. By comparison, only eight patients (28%) managed with microsurgical fenestration and four (36%) in the shunted group needed a second surgical procedure. Mean follow-up was 30 months. In the surgical series 79% (n = 45) had a good outcome.We conclude that the surgical treatment of arachnoid cysts has an overall good outcome. In our institution the best results were obtained with microsurgical decompression through craniotomy.

Research of efficiency and safety of Vasonat has been carried out. 31 patients aged 46-75 years who had had hemispheric athero- thrombotic or hemodynamic schemic stroke with moderate severity and being treated in 2-5-month of early rehabilitation period have been observed. The control group of patients received placebo. Results of the study, 4 weeks treatment using Vasonat in the dosage of 500 mg/day have shown positive effect on common signs of the disease by decreasing headache intensity, dizziness, a nausea, and on focal neurological symptoms by decreasing hemiparesis degree; psychoemotional and mnestic activity (main memory and attention) improved as well. It was more distinct in patients with localization of the stroke in the right hemisphere of the brain. It was also noted more rapid improvement of motion function and quality of life of patients.

Cervical pain caused by the elongation of the styloid process (Eagle syndrome) is well known to otolaryngologists but is rarely considered by vascular surgeons. We report two patients with cerebrovascular symptoms of Eagle syndrome treated in our medical center in the past year. Case 1: an 80-year-old man with acromegaly presented with dizziness and syncope with neck rotation. The patient was noted to have bilateral elongated styloid processes impinging on the internal carotid arteries. After staged resections of the styloid processes through cervical approaches, the symptoms resolved completely. Case 2: a 57-year-old man presented with acute-onset left-sided neck pain radiating to his head immediately after a vigorous neck massage. Hospital course was complicated by a 15-minute transient ischemic attack resulting in aphasia. Angiography revealed bilateral dissections of his internal carotid arteries, with a dissecting aneurysm on the right. Both injuries were immediately adjacent to the bilateral elongated styloid processes. Despite immediate anticoagulation therapy, he experienced aphasia and right hemiparesis associated with an occlusion of his left carotid artery. He underwent emergent catheter thrombectomy and carotid stent placement, with near-complete resolution of his symptoms. Elongated styloid processes characteristic of Eagle syndrome can result in both temporary impingement and permanent injury to the extracranial carotid arteries. Although rare, Eagle syndrome should be considered in the differential diagnosis in patients with cerebrovascular symptoms, especially those induced by positional change.

A rare syndrome, Dyke-Davidoff-Masson Syndrome (DDMS), with a diagnostic conundrum, and the way it was solved is presented. A 13-year-old boy presented with recurrent seizures for the past 10 years. He had been treated with anticonvulsant medication which was satisfactory at first but later the seizures recurred. Recently, the frequency of the seizures increased with preictal dizziness and postictal drowsiness. Physical examination revealed mild left hemiparesis and left deviated gait irregularity. He was mentally alert but had not achieved all the developmental milestones as compared to normal child of his age. CT and MRI scan of the head showed hemiatrophic cerebral parenchyma with prominent sulci and encephalomalacia. 24-hour intensive video EEG monitoring revealed suppression of alpha rhythm and local slow wave activity on the side of the atrophic hemisphere. PET-CT showed highly functional left cerebral hemisphere and less functional right cerebral hemisphere. The patient underwent functional hemispherectomy under neurophysiological monitoring and the nonfunctional brain tissues were resected while selectively preserving the functional areas detected by fMRI and PET-CT scan. During follow up, the patient was seizure free as well as without difficulties in performing his daily activities and communications. Functional hemispherectomy for DDMS patient has a good prognosis.

We describe a 25-year-old woman that presented with frequent rotational dizziness, visual loss of the right eye one month later, and unilateral deafness one year after. After 2 years, she presented with a right hemiparesis and deafness greater for low frequency tones. Magnetic resonance imaging with angiography of the brain showed constriction in the first segment of the cerebral anterior artery diagnosed as Susacs syndrome.
