Pictorial Essay of Cervical Duplex Ultrasonography.

: Cervical duplex ultrasonography (CDU) is a simple, non-invasive, portable technique, that provides valuable high-quality visual information about the integrity of the carotid and vertebral vessels, plaque morphology and flow hemodynamics. CDU is useful in the assessment and follow up of patients with cerebrovascular disease as well as other conditions like inflammatory vasculitis, carotid artery dissection and carotid body tumours. CDU is inexpensive and invaluable in smaller centres.

MRI outcomes in patients with acute-onset vertigo in the emergency department - A prospective study.

Introduction: Vertigo is an abnormal sensation of motion which arises due to a mismatch between various sensory modalities involved in maintaining balance. Vertigo can be due to central or peripheral causes and intensely debilitating for some patients. Acute onset vertigo is defined as the commencement of vertigo within 24 h.

A rare cause of median neuropathy at the carpal tunnel: Thrombosis of the persistent median artery.

Carpal tunnel syndrome is a common peripheral nerve entrapment neuropathy caused due to compression of the median nerve at the level of the wrist joint. Bifid median nerve associated with a persistent median artery is a rare entity and in itself asymptomatic anatomical variant. However, distension of the persistent median artery due to a thrombus can be symptomatic due to compression on the median nerve and can compromise the blood flow to the palm.

An unusual case of Takayasu's arteritis: Evaluation by CT angiography.

Takayasu's arteritis is a chronic, idiopathic, medium and large vessel vasculitis involving aorta and its main branches. Frequent neurological manifestations include postural syncope, seizures, and blindness. Stroke, as presenting feature of Takayasu's arteritis, is unusual.

Initial clinical and radiological findings in patients with SSPE: are they predictive of neurological outcome after 6 months of follow-up?

Subacute sclerosing panencephalitis (SSPE) is a progressive, devastating neurologic disorder caused by mutant measles virus. In this study we evaluated the prognostic value of neuroimaging abnormalities in SSPE. Thirty consecutive patients with SSPE were included.

Intracranial tuberculomas in patients with tuberculous meningitis: predictors and prognostic significance.

Setting: Intracranial tuberculomas are commonly observed neuroimaging abnormalities in tuberculous meningitis (TBM).

Objective: to evaluate the predictors and prognostic significance of tuberculomas in patients with TBM.

Design: In a retrospective follow-up study, contrast-enhanced magnetic resonance imaging was performed at study inclusion and after 9 months of follow-up.

Predictors of stroke in patients of tuberculous meningitis and its effect on the outcome.

Background: Stroke is a devastating complication of tuberculous meningitis and is an important determinant of its outcome.

Aim: To prospectively evaluate the predictive factors for stroke in patients with tuberculous meningitis and to assess the impact of stroke on the overall prognosis and outcome.

Methods: We evaluated and followed 100 patients of tuberculous meningitis for 6 months.

Paradoxical vision loss associated with optochiasmatic tuberculoma in tuberculous meningitis: a report of 8 patients.

Background: Paradoxical appearance of new or expansion of existing optochiasmatic tuberculoma, leading to severe vision loss, is a devastating complication in patient with tuberculous meningitis.

Methods: We report a series of 8 cases of tuberculous meningitis that developed paradoxical vision loss associated with optochiasmatic tuberculoma. Clinical assessment and magnetic resonance imaging (MRI) done at presentation, at the time of deterioration, and at 9 months were analyzed.

Vision impairment in tuberculous meningitis: predictors and prognosis.

Background: Vision impairment is a devastating complication of tuberculous meningitis. In the present study we evaluated the predictors and prognostic significance of vision impairment in tuberculous meningitis.

Methods: In this study, 101 adult patients with tuberculous meningitis were evaluated for vision status and physical disability and were followed up for 6 months.
