Déjerine-Roussy syndrome presenting with atypical involuntary movements.

BACKGROUND: The Déjerine-Roussy syndrome is caused by a stroke in the posterior lateral nuclei of the thalamus. It has a 17 to 18% prevalence after a stroke involving the inferior lateral thalamus. METHODS: We reported a case of a 65-year-old, diabetic and hypertensive male who presented with sudden onset of superficial hemianesthesia, allodynia, severe and paroxysmal pain on the right side of the body with choreoathetoid movements in the upperN limb, along with slured speech, and unsteadiness while walking. CONCLUSIONS: It is characterized by superficial hemianesthesia, allodynia, severe paroxysmal pain, and choreoathetoid movements in the limbs on the paralyzed side. A posterior lateral thalamic lesion can present with ataxia hemiparesis contralateral to the side of the lesion.

Severe acute orthostatic headache: spontaneous intracranial hypotension (SIH).

The most common cause of spontaneous intracranial hypotension headache is a cerebrospinal fluid (CSF) leakage, but the underlying mechanisms remain unknown. Intracranial hypotension is characterised by diffuse pachymeningeal enhancement on cranial MRI features, low CSF pressure and orthostatic headaches mostly caused by the dural puncture. We report a 31-year-old woman who presented to our services with reports of continuous severe bifrontal headache, which increased on sitting up and resolved on lying down. MRI of the cervical and lumbosacral spine showed signs of CSF leak; hence, patient was diagnosed with spontaneous intracranial hypotension headache. A CT-guided epidural blood patch was done at L4-5 with fibrin glue injected at the site of leak. The patient's signs and symptoms improved after the procedure.

Paraneoplastic Cerebellar Degeneration Associated With Ovarian Adenocarcinoma: A Case Report and Review of Literature.

Paraneoplastic syndromes are a rare heterogeneous group of disorders that are indicators of the underlying occult malignancy. Subacute cerebellar ataxia in a patient with a known cancer is often due to metastatic invasion or other complications of the cancer, such as infection, coagulopathy, metabolic and nutritional deficits, or side effects of treatment. When tumor- and treatment-related causes have been excluded, the patient is considered to suffer from paraneoplastic cerebellar degeneration (PCD). We report a case of PCD that presented before any evidence of tumor, but early diagnostic workup and clinical vigilance helped us to find the underlying high-grade ovarian adenocarcinoma which was surgically removed later.

Nocardia Farcinica Brain Abscess in an Immunocompetent Old Patient: A Case Report and Review of Literature.

By definition, a brain abscess is an intraparenchymal collection of pus. Nocardia shows to have a special tropism for the neural tissue. Solitary abscess represents the most common manifestation in the central nervous system, accounting for 1%-2% of all cerebral abscesses. In this report, we present a case of primary multiple brain abscesses due to Nocardia farcinica in an immune competent patient. Early diagnosis and surgical intervention is significant for the patient.
