Headache in cerebral venous sinus thrombosis revisited: Exploring the role of vascular congestion and cortical vein thrombosis.

Background and purpose Headache constitutes the most common symptom of cerebral venous sinus thrombosis (CVST), but its pathophysiology is unclear. We sought to investigate the potential mechanism for headache genesis in patients with CVST based on its imaging correlates. Methods A subgroup of CVST patients having headache as the predominant symptom without significant parenchymal lesion were retrospectively analysed for imaging features of vascular congestion (VC), in addition to cortical venous (CVT) and dural sinus thrombosis (DST) on magnetic resonance imaging.

Intractable vomiting and hiccups as the presenting symptom of neuromyelitis optica.

Vomiting and hiccups can be due to peripheral or central causes. Neurological diseases causing vomiting and hiccups are due to lesions of medulla involving area postrema and nucleus tractus solitarius. Neuromyelitis optica (NMO) is one such disease which involves these structures.

Cystic cochleovestibular anomaly presenting with congenital deafness and recurrent bacterial meningitis in childhood.

Recurrent bacterial meningitis (RBM) in many instances is associated with identifiable anatomical defects. Presence of congenital deafness with recurrent meningitis should alert clinician for presence of middle and inner ear malformation. These defects can be demonstrated by various neuro imaging techniques and can be surgically corrected.

Lower motor neuron facial palsy in cerebral venous sinus thrombosis.

With advances in the neuro-imaging modalities, diverse manifestations of the cerebral venous sinus thrombosis (CVT) are being recognized. There are very few reports of isolated cranial nerve palsies in CVT. In this case report, we describe a patient of lower motor neuron facial palsy with CVT who was successfully treated with anticoagulation, highlighting the atypical manifestation of the disease.
