Spontaneous intracranial hypotension (SIH) is an unusual syndrome that is characterised by positional headache, neck rigidity, nausea and vomiting. The characteristic magnetic resonance imaging (MRI) findings are diffuse smooth pachymeningeal thickening and enhancement, downward displacement of posterior fossa structures and pituitary gland enlargement. An unusual case of SIH with pituitary macro-adenoma and subsequent subdural haemorrhage is presented, and its clinical picture, MRI findings and possible pathophysiological mechanism are discussed.

Role of CT myelography in the diagnosis and management of spontaneous intracranial hypotension.
Clin Neurol Neurosurg

Introduction: Spontaneous intracranial hypotension (SIH) is a secondary cause of headache. Its pathophysiology is complex, and relies mainly on the notion of a localized leak, and thus a loss of cerebrospinal fluid (CSF) in the spinal region. SIH is little known to the medical profession, for which CT myelography is a technique on the rise, allowing to identify and treat the leak using a blood-patch or a fibrin sealant.

Background: Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe headaches, often thunderclap headaches, and a multifocal constriction of the cerebral arteries. Although RCVS can occur spontaneously, some cases occur after exposure to drugs. We describe the first case of RCVS in which methylphenidate, a drug with vasoconstrictive properties, is the only suspected drug.

Background: Post-traumatic stress disorder (PTSD) causes intrusive symptoms and avoidance behaviours due to dysregulation in various brain regions, including the hippocampus. Deep brain stimulation (DBS) shows promise for refractory PTSD cases. In rodents, DBS improves fear extinction and reduces anxiety-like behaviours, but its effects on active-avoidance extinction remain unexplored.

Department of Internal Medicine, Aga Khan University Hospital, Nairobi, KEN.
Post-dural puncture headaches usually occur when the cerebrospinal fluid (CSF) leaks due to trauma to the dura mater. This often results in spontaneous intracranial hypotension characterized by orthostatic headaches, neck stiffness, and nausea. In this case report, we discuss a 20-year-old male patient who developed symptoms of intracranial hypotension one year following a lumbar puncture.
