The role of imaging in skull base osteomyelitis - Reviewed.

Purpose: Skull base osteomyelitis (SBO) is difficult to diagnose due to a wide array of clinical presentations. It can be life threatening if not treated promptly. The objective of this study is to identify the various neck spaces involved in skull base osteomyelitis, correlate them with the possible source of infection and identify the related complications.

An Unusual Cause of Chronic Headache in an Adolescent Boy: A Case Report.

Spontaneous intracranial hypotension (SIH) is an under-diagnosed cause of headache in children and adolescents. SIH results from cerebrospinal fluid (CSF) leak due to breach in the dura mater and the etiology for dural breach is often diverse. We report an adolescent boy who presented with chronic episodic headache that later progressed to daily headache.

Imaging Spectrum of Cavernous Sinus Lesions with Histopathologic Correlation.

Cavernous sinuses are paired interconnected venous plexuses situated in the floor of the middle cranial fossa on either side of the sella turcica and sphenoid sinus. They are lined by dura mater and consist of multiple venous channels within. The cavernous sinuses are intimately related to the internal carotid artery and its associated sympathetic plexus, the oculomotor nerve, the trochlear nerve, the abducens nerve, and the ophthalmic nerve.

Reliability of Imaging-Based Diagnosis of Lateral Ventricular Masses in Children.

Objective: We studied the accuracy of the radiologic diagnosis of lateral ventricular masses in children (<20 years of age).

Methods: In this retrospective study, data were collected from children with lateral ventricular masses managed in our unit between 2001 and 2016. There were 43 patients (26 boys and 17 girls; mean age, 12.

Role of Noninvasive Imaging of Cerebral Arterial System in Ischemic Stroke: Comparison of Transcranial Color-coded Doppler Sonography with Magnetic Resonance Angiography.

Aim: To determine the accuracy of transcranial color-coded Doppler sonography (TCCS) in the evaluation of cerebral arterial system in patients with ischemic stroke attending a tertiary care hospital in South India.

Objectives: (1) To describe the topographical distribution of atherosclerotic lesions in the cerebral circulation in patients presenting with ischemic stroke from the Indian subcontinent and (2) to determine the accuracy of TCCS for detection and quantification of intracranial stenoses in various segments of the intracerebral arterial system in comparison with magnetic resonance angiography (MRA).

Materials And Methods: The demographic profile and risk factors of consecutive patients who presented to neurology outpatient department with cerebral ischemia and scheduled for MRA were determined.

Role of penumbra mechanical thrombectomy device in acute dural sinus thrombosis.

Background: In dural venous sinus thrombosis (DVST), the mortality ranges 5-30%. Deep venous system involvement and septic dural sinus thrombosis have a higher mortality rate. In acute occlusion, collateral flow may not be established, which may result in significant edema and mass effect.

Pediatric Balint's Syndrome Variant: A Possible Diagnosis in Children.

Balint's syndrome is well described in adults, but not in children. It is caused by bilateral posterior parietal lobe damage and comprises a triad of simultanagnosia (inability to simultaneously see more than a small number of items), optic ataxia (impaired visual guidance of movement of the limbs and body), and apraxia of gaze (inability to volitionally direct gaze despite the requisite motor substrate) often associated with homonymous lower visual field loss. We, here, describe five children (four males, one female; mean age 7.

Proximal Interruption of the Pulmonary Artery: A Case Series.

We present a few cases of Proximal Interruption of the Pulmonary Artery, an uncommon developmental anomaly associated with congenital heart disease. The cases had varied clinical presentations. Chest radiograph showed a hypoplastic lung with an ipsilateral small hilum on the side of the interruption and hyperinflation of the contralateral lung.

Tuberculosis--the great mimicker.

Tuberculosis is an immense health problem in the developing world, and it remains a health care challenge in the developed world. It can affect virtually any organ system in the body. Diagnosis of tuberculosis is often difficult.

Recurrent craniospinal subarachnoid hemorrhage in cerebral amyloid angiopathy.

Cerebral amyloid angiopathy (CAA) usually manifests as cerebral hemorrhage, especially as nontraumatic hemorrhages in normotensive elderly patients. Other manifestations are subarachnoid (SAH), subdural, intraventricular hemorrhage (IVH) and superficial hemosiderosis. A 52-year-old hypertensive woman presented with recurrent neurological deficits over a period of 2 years.

Leflunomide with low-dose everolimus for treatment of Kaposi's sarcoma in a renal allograft recipient.

Current treatment of Kaposi's sarcoma is reduction of immunosuppression with or without addition of mammalian target of rapamycin inhibitors (mTORi). Akt signalling plays a central role in oncogenesis of Kaposi's sarcoma. We describe a case of multifocal Kaposi's sarcoma in a renal allograft recipient, which showed unsatisfactory early response to immunosuppression reduction along with everolimus therapy but completely resolved after adding leflunomide.
