1/52. An 11-year-old girl with syndrome of inappropriate antidiuretic hormone secretion.An 11-year-old girl presented with a syndrome of inappropriate antidiuretic hormone secretion, which was transitory and, initially, of obscure origin. Subsequently, the patient's hypothalamic disorder emerged as a component of a steroid-responsive relapsing encephalomyelitis with cerebral pathology restricted to the basal ganglia and brainstem. Where such a disorder fits in the spectrum from acute disseminating encephalomeylitis to multiple sclerosis is discussed.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
2/52. Parietal cheiro-oral syndrome.Cheiro-oral syndrome due to a parietal lesion has been reported in conjuction with a brain tumor, infarction and migraine. Only six reports of cheiro-oral syndrome due to a parietal infarction have been reported to date. We treated a 45-year-old woman with cheiro-oral syndrome due to a parietal infarction. Her sensory disturbance was characterized by paresthesia in the lower face and hand on the left side, and severe involvement of stereognosis and graphesthesia in the left hand. The pathogenesis of parietal cheiro-oral syndrome is discussed.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
3/52. Dysesthesia perceived as painful spasticity: A report of 3 cases.Lesions of the central nervous system often involve the pyramidal tracts and the sensory pathways to produce spasticity, paresthesias, and dysesthesia. Three patients with intractable spasticity were treated with intrathecal baclofen. Two had an implanted Medtronic SynchroMed pump for long-term delivery of the muscle relaxant. The third patient had undergone a screening trial in which the baclofen was delivered into the intrathecal space through a lumbar catheter. All had excellent relief of spasms on clinical examination, but they reported painful spasms particularly at night. Two of the patients were successfully treated for dysesthesia.- - - - - - - - - - ranking = 5.0132158267389keywords = nervous system, central nervous system (Clic here for more details about this article) |
4/52. Post-apopletic trigeminal trophic syndrome.Trigeminal trophic syndrome is an uncommon clinical entity in which cutaneous trophic ulceration develops with continuous manipulation of trigeminal dermatomes. patients spontaneously refer picking, rubbing and/or scratching at the affected areas because of hypo-anaesthesia, paraesthesia and/or pain following damage of the sensory trigeminal fibres or nuclei. We herein describe a patient who developed the syndrome as a sequela of brain stem infarction. Diagnosis by scrape cytology in ruling-out basal cell carcinoma and other ulcerative skin diseases is discussed and the importance of neurological examination in disclosing hemi-anaesthesia of trigeminal dermatome(s) is emphasized.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
5/52. Metastatic head and neck squamous cell carcinoma to the brain.BACKGROUND: To evaluate the natural history of patients with metastatic squamous cell carcinoma (SCCA) of the head and neck to the brain. methods: A retrospective review of patients with brain metastases treated over a 20-year period identified five that had a head and neck SCCA primary. RESULTS: Five cases of patients with SCCA of the head and neck that developed brain metastases are presented in detail. CONCLUSION: In patients with aggressive disease, large infiltrative lesions, and in late survivors with initially advanced disease, metastasis to the brain should be considered. Perineural metastasis appears to be the most common mode of spread of head and neck SCCA to the brain. Pain, paresis, or paresthesias in the distribution of cranial nerves or other neurological symptoms should alert the otolaryngologist to neural or central nervous system involvement in patients with SCCA of the head and neck. Surgery with or without post-operative whole brain radiation therapy is the mainstay of treatment in most patients. Stereotactic radiosurgery may play a major role in treating brain metastases from head and neck primary tumors.- - - - - - - - - - ranking = 16.013215826739keywords = nervous system, central nervous system, brain (Clic here for more details about this article) |
6/52. Reversible myelopathy in a 34-year-old man with vitamin B12 deficiency.Vitamin B12 deficiency is common, with most patients lacking classic features of advanced severe deficiency. early diagnosis and treatment prevent severe anemia and irreversible damage to the nervous system. We describe a 34-year-old man with pernicious anemia who presented with clinical and radiologic features of early myelopathy and borderline low serum levels of vitamin B12. Prompt diagnosis based on the measurement of serum methylmalonic acid and treatment with cyanocobalamin injections led to rapid resolution of clinical manifestations and magnetic resonance imaging abnormalities. We review the literature of magnetic resonance imaging in vitamin B12 deficiency myelopathy and discuss the issues relating to diagnosis and early treatment of this potentially reversible condition.- - - - - - - - - - ranking = 3.6676158267389keywords = nervous system (Clic here for more details about this article) |
7/52. Conversion sensory symptoms associated with parietal lobe infarct: case report, diagnostic issues and brain mechanisms.This case report suggests that diagnostic difficulties and brain mechanisms related to conversion disorder associated with cerebral lesions differ from those related to conversion disorder without cerebral lesions. A 35-year-old divorced woman was admitted to a psychiatric inpatient unit with multiple physical complaints. The symptoms first appeared 5 years previous and 2 months after a sexual assault. Three years later, she began to experience ill-defined sensory symptoms confined to the left half of her body (splitting the midline). Results of neurologic consultations were equivocal because of the subjective nature of the complaints, which were viewed as conversion symptoms. A magnetic resonance imaging scan demonstrated an old infarct in the right parietal lobe, suggesting a physical origin of the patient's symptoms. However, normal somatosensory-evoked responses from the affected area contributed little to establishing the diagnosis. The results of all further investigations to identify causes of the vascular pathology were negative. The multiple ill-defined somatic symptoms, the distribution of sensory symptoms and the resolution of symptoms with psychotherapy established the diagnosis of conversion disorder superimposed on a pre-existing right parietal lesion. This case highlights the importance of clinical features in establishing a diagnosis such as this. We suggest that reactivation of implicit sensory memories (represented at the thalamic level and resulting from decreased corticofugal inhibitions due to the lesion) may contribute to the formation of sensory conversion symptoms in individuals with parietal lobe lesions.- - - - - - - - - - ranking = 5keywords = brain (Clic here for more details about this article) |
8/52. Anterior transpetrosal approach for pontine cavernous angioma--case report.A 58-year-old male patient presented with headache and unsteady gait. magnetic resonance imaging revealed hemorrhage from a pontine cavernous angioma. The patient experienced stepwise aggravation of symptoms due to repeated hemorrhages. We decided to surgically remove the pontine cavernous angioma through an anterior transpetrosal approach, since the angioma and hematoma were located near the ventrolateral surface of the pons. The brain stem was incised at a site caudal to the trigeminal nerve and the hematoma and angioma were totally removed. No additional neurological deficits were observed following surgery. brain stem cavernous angiomas are usually removed via a trans-fourth ventricle or lateral suboccipital approach. However, these approaches may not be appropriate if the angioma is located ventrally to the pons. We propose that the anterior transpetrosal approach is the method of choice for ventrally located pontine cavernous angioma.- - - - - - - - - - ranking = 1keywords = brain (Clic here for more details about this article) |
9/52. Neurofibromatosis type I: clinical and imaging features of Von Recklinghausen's disease.OBJECTIVE: To discuss the case of a 45-year-old woman, with a prior diagnosis of neurofibromatosis type 1 (NF-1), complaining of low back and cervical spine pain with bilateral upper extremity paresthesias. CLINICAL FEATURES: The patient had a dull, achy, constant low-back pain of 4 months' duration, with mild headaches and upper extremity paresthesias. Multiple skin lesions and spinopelvic postural imbalances were present. Diagnostic radiography, along with advanced imaging, demonstrated multilevel dysplastic osseous changes, with dural ectasia, scoliosis, and tumor extension. In addition to the previous diagnosis of NF-1, our clinical diagnosis included segmental dysfunction with resultant cervicalgia, lumbalgia, and myospasm. INTERVENTION AND OUTCOME: Treatment consisted of a course of spinal manipulation of the lumbopelvic region, with adjunctive therapy consisting of interferential therapy, heat, and rehabilitative exercise. Marked reduction in pain and paresthesia with improved function were achieved. CONCLUSIONS: NF-1 is a multisystem disease with neoplasia of the skin and nervous system. patients experience a lifetime of morbidity and increased risk of mortality, depending on the extent of the disease. A multitude of therapeutic regimens may be engaged to improve NF-1-associated symptomatology and morbidity. chiropractic spinal manipulation may have a positive effect in pain reduction and improved function in patients who have NF-1 without spinal instability.- - - - - - - - - - ranking = 3.6676158267389keywords = nervous system (Clic here for more details about this article) |
10/52. Recurrent arachnoid cyst of Meckel's cave mimicking a brain stem ischaemia. Report of a rare case.A 44-years old man developed TIA-like symptoms with dysaesthesia around the mouth, vertigo and diplopia. MRI revealed a cystic space-occupying lesion on the right Meckel's cave, which spread out into cerebellopontine angle in a further examination. Therefore surgical exploration was performed using a suboccipital approach. An arachnoidal cyst was found and removed including its wall. About three months later the patient suffered again from dysaesthesias of the right side of the face and a new MRI revealed a recurrence of the lesion, with extension into the cerebellopontine angle, too. Surgical revision was done using the same approach and the recurrent cyst was removed. Postoperatively, there were a transient hypaesthesia in the distribution area of the right trigeminal nerve and a light pulmonary embolism occurred as a complication. No symptoms have returned during an observation period of 15 months. CONCLUSION: An arachnoidal cyst must be considered as a rare cause, when a lesion is found at the Meckel's cave with intermittent clinical symptoms of a trigeminal nerve affection. As surgical treatment we favour fenestration and cyst wall resection.- - - - - - - - - - ranking = 4keywords = brain (Clic here for more details about this article) |
