2/13. radiation therapy and combination of cladribine, cyclophosphamide, and prednisone as treatment of Bing-Neel syndrome: Case report and review of the literature.Waldenstrom's macroglobulinemia is a low-grade lymphoma that produces monoclonal IgM. central nervous system symptoms are frequent in Waldenstrom's macroglobulinemia, mostly associated with blood hyperviscosity. Nevertheless, central nervous system infiltration by malignant cells (Bing-Neel syndrome) has rarely been reported. We describe the case of a 72-year-old man with Waldenstrom's macroglobulinemia and central nervous system infiltration by malignant cells with tumor formation. All similar cases reported in the literature are reviewed and the different therapeutic approaches discussed.- - - - - - - - - - ranking = 0.6keywords = nervous system (Clic here for more details about this article) |
3/13. Lyme carditis: restitutio ad integrum documented by cardiac magnetic resonance imaging.lyme disease is a tickborne illness that could cause, weeks to months later, complications involving the joints, central nervous system, and cardiovascular system. We report a case of cardiac manifestation with transitory higher degree atrioventricular block and dysfunction of the left ventricle. Complete resolution without signs of myocardial scar is demonstrated by cardiac magnetic resonance imaging.- - - - - - - - - - ranking = 0.2keywords = nervous system (Clic here for more details about this article) |
4/13. Cavernous malformation of the trigeminal nerve manifesting with trigeminal neuralgia: case report.OBJECTIVE AND IMPORTANCE: We describe a patient with a cavernous malformation within the trigeminal nerve at the nerve root entry zone who presented with trigeminal neuralgia. CLINICAL PRESENTATION: A 52-year-old woman sought treatment after experiencing dizziness and lancinating left facial pain for almost a year. Neurological examination revealed diminished sensation in the distribution of the trigeminal nerve on the left. magnetic resonance imaging demonstrated a minimally enhancing lesion affecting the trigeminal nerve. INTERVENTION: The patient underwent a retrosigmoid craniotomy. At the nerve root entry zone, the trigeminal nerve was edematous with hemosiderin staining. The lesion, which was resected with microsurgical technique, had the appearance of a cavernous malformation on gross and histological examination. The patient's pain improved significantly after resection. CONCLUSION: Cavernous malformations can afflict the trigeminal nerve and cause trigeminal neuralgia. Microsurgical excision can be performed safely and is associated with improvement in symptoms.- - - - - - - - - - ranking = 0.25457956479842keywords = malformation (Clic here for more details about this article) |
5/13. Chiari I malformation with or without syringomyelia and pregnancy: case studies and review of the literature.women with Chiari I malformation with or without syringomyelia are of particular concern because of the potential risk of increased intracranial pressure during pregnancy and delivery. The following questions are most often asked in the clinical setting: Is it safe to have a planned pregnancy? Will the symptoms become worse or recur during pregnancy and will the baby be normal? Seven patients with Chiari I malformation, with and without syringomyelia, submitted checklists of self-reported symptoms experienced during pregnancy, labor, and postpartum. Seven patients with Chiari I malformation with and without syringomyelia were queried for symptoms during pregnancy, labor, and postpartum. None of the patients reported significant increase or recurrence of Chiari-related symptoms during delivery or postpartum. Four of the women had epidural anesthesia for delivery and reported no related symptoms. This series represents a small number of women with Chiari I malformation who had uncomplicated pregnancy, labor, and delivery.- - - - - - - - - - ranking = 0.29094807405534keywords = malformation (Clic here for more details about this article) |
6/13. Large cystic cavernous angioma of the cerebellum mimicking pilocytic astrocytoma.OBJECTIVE AND IMPORTANCE: Cavernous angiomas are relatively rare vascular malformations. They are generally located supratentorially with a rare incidence in the cerebellum. Cavernous angiomas, accompanied by a large cyst, are very rare. We present a case of a cavernous angioma with the unusual MRI findings of a large cyst and a small mural nodule. CLINICAL PRESENTATION: The patient was a 48-year-old man who complained of a history of dizziness for several weeks. The neurologic examination in the neurosurgery clinic was without deficit. INTERVENTION: The cyst measured 4.7x4.0 cm and contained serous fluid with a nodular mass in the lower part of the cyst. The cystic wall and the solid mural nodule were completely removed through a midline suboccipital approach. Postoperatively, the patient remained neurologically intact. CONCLUSION: When a large cystic lesion is present in the cerebellum, preoperative radiological and intraoperative findings led to misdiagnosis. Therefore, a rare cystic angioma must be considered in the differential diagnosis of infratentorial cystic masses.- - - - - - - - - - ranking = 0.036368509256918keywords = malformation (Clic here for more details about this article) |
7/13. temporal bone findings in central nervous system leukemia.central nervous system (CNS) leukemia is a pathologic condition whereby leukemic cells enter the cerebrospinal fluid (CSF) causing meningeal irritation syndrome. temporal bone findings in the case of a 32-year-old man who died of CNS leukemia are presented. He complained of fullness of the ear 4 months prior to death and of dizziness 1 month prior to death. Leukemic cells were seen to have infiltrated the scala tympani of the basal turn in the cochlea, the saccule, and posterior semicircular canal along the vestibulocochlear nerve.- - - - - - - - - - ranking = 1keywords = nervous system (Clic here for more details about this article) |
8/13. dizziness due to dysautonomia: response to specific therapy.We have reported a case of hypervagal dysautonomia in which there was improvement in the results of autonomic nervous system tests (ANSTs) as well as in the patient's symptoms. This patient is one of more than 200 patients who have had our testing protocol. Although a high percentage of autonomic dysfunction was detected in this group of patients, we do not suggest that these tests be applied routinely to every patient complaining of dizziness. Rather, ANSTs should be selectively administered after otologic disease has been excluded and when dizziness is accompanied by various other symptoms.- - - - - - - - - - ranking = 0.2keywords = nervous system (Clic here for more details about this article) |
9/13. Primary dysfunction of the afferent limb of the arterial baroreceptor reflex system in a patient with severe supine hypertension and orthostatic hypotension.A 33 year old man with a history of recurrent episodes of orthostatic dizziness since adolescence was noted to have a supine blood pressure of 200/120 mm Hg and a standing blood pressure of 90/60 mm Hg. Results of extensive laboratory studies for secondary hypertension were negative. Studies of the autonomic nervous system function revealed normal plasma catecholamines, cold pressor test and response to 4 minute 30% of maximal static handgrip contraction and an appropriate increase in heart rate on intravenous injection of atropine. In contrast, the heart rate response to phenylephrine and sodium nitroprusside infusion, carotid massage and graded neck suction with an airtight chamber was very abnormal, indicating marked dysfunction of the afferent limb of the arterial baroreceptor reflex system. methyldopa decreased the supine hypertension and increased the standing blood pressure.- - - - - - - - - - ranking = 0.2keywords = nervous system (Clic here for more details about this article) |
10/13. Postural heart block.A patient presented with orthostatic dizziness and syncope caused by postural heart block. When the patient was supine, atrioventricular conduction was normal and he was asymptomatic; when he was standing he developed second degree type II block and symptoms. The left bundle-branch block on his electrocardiogram and intracardiac electrophysiological study findings suggest that this heart block occurred distal to the His bundle. Orthostatic symptoms are usually presumed to be secondary to an inappropriate distribution of intravascular volume or to autonomic nervous system abnormalities. As shown in this patient, these symptoms may be the result of orthostatic heart block. Ambulatory monitoring may be useful in patients with orthostatic neurological symptoms, particularly when conduction abnormalities are present on the electrocardiogram.- - - - - - - - - - ranking = 0.2keywords = nervous system (Clic here for more details about this article) |
