An Audit of Tracheostomy in Traumatic Brain Injury.

Introduction: The timing of tracheostomy in traumatic brain injury is controversial. The benefits of early tracheostomy are early weaning from ventilation, and reduction in pneumonia. But some studies demonstrated increase in intracranial pressure during tracheostomy.

A Review of the Diagnostic Features of Posteriorly Migrated Lumbar Discs with Reports of Two Cases.

Background: The radiological features of posteriorly migrated intervertebral discs mimic tumors, hematoma, and abscess.

Objective: The aim is to analyze two cases of posteriorly migrated lumbar discs.

Cases: Two males had features of cauda equina syndrome.

A case of neurenteric cyst of spine mimicking an arachnoid cyst.

Background: Intradural cysts of the spine are arachnoid cysts, neuroenteric cysts, and ependymal cysts. The usual finding in case of a neurenteric cyst is a ventrally located non-contrast-enhancing lesion that is isointense on T1-weighted sequence and hyperintense on T2-weighted imaging. An arachnoid cyst is hypointense in T1-weighted image and hyperintense in T2-weighted image, mimicking cerebrospinal fluid(CSF), and the location is dorsal to the cord.

A brief review of the neurological manifestations of the coronavirus disease.

Introduction: It has been demonstrated experimentally that the coronavirus can enter the central nervous system through olfactory nerves and can even reach medulla. Neurological manifestations are observed more frequently in patients with coronavirus disease.

Main Text: The aim of the review is to seek evidence for infection of the nervous system by the human coronavirus and study the neurological manifestations of the coronavirus and its treatment.

Case report of lumbar intradural capillary hemangioma.

Background: Capillary hemangioma is a rare tumor in spinal intradural location. Despite the rarity, early recognition is important because of the risk of hemorrhage. This is a case report of a woman who had capillary hemangioma of cauda equina.
