Lung parenchymal changes in patients with ankylosing spondylitis.

Aim: To assess lung parenchymal changes in ankylosing spondylitis (AS) using high resolution computed tomography (HRCT).

Methods: We included 78 AS patients whose average age was 33.87 (18-56) years with a ratio of 53 males to 25 females who were followed up for 3.

Assessment of CSF flow dynamics using PC-MRI in spontaneous intracranial hypotension.

Aim: Spontaneous intracranial hypotension (SIH) is caused by spontaneous cerebrospinal fluid (CSF) leaks and is known to cause orthostatic headaches. Phase-contrast magnetic resonance imaging (PC-MRI) is a non-invasive technique that can be used to quantify variation in CSF flow. The aim of this study was to assess CSF flow dynamics using PC-MRI in SIH.

Pathological contrast enhancement of the oculomotor and trigeminal nerves caused by intracranial hypotension syndrome.

The typical symptom of intracranial hypotension syndrome is orthostatic headache. The headache may also be accompanied by neck pain and stiffness, low backache, radicular symptoms, quadriplegia, interscapular pain, nausea/vomiting, and cranial nerve involvement symptoms (hearing and visual problems, face pain and numbness, hypogeusia). Radiologically, on cranial magnetic resonance imaging, intracranial hypotension syndrome is characterized by dural thickening and contrast enhancement, subdural effusion, engorgement of the venous structures, sagging or downward displacement of the brain, and pituitary hyperemia.
