“…4 Raised ICP may also cause brain herniation, a potentially life-threatening complication. 5 Visual manifestations of papilloedema may be quite subtle and even patients with significant papilloedema may be visually asymptomatic. The most common visual presenting symptom is transient visual obscuration.…”

Papilloedema is a diagnostic term used exclusively to describe optic disc oedema associated with increased intracranial pressure. Septic cerebral venous sinus thrombosis has become an increasingly rare cause of papilloedema because of the widespread availability of antimicrobial agents; however, it is imperative for optometrists to maintain vigilance for this pathologic process. Presented is a case of a 77‐year‐old Caucasian male with a complaint of blurred vision and non‐specific, diffuse headache. He had a right sixth cranial nerve palsy and bilateral disc oedema. Raised intracranial pressure was confirmed by lumbar puncture. Neuroimaging, including magnetic resonance imaging and magnetic resonance venography in conjunction with cytological assessment of the cerebral spinal fluid led to a probable diagnosis of mastoiditis causing multiple dural venous sinus thrombi of the superior sagittal and right transverse sinuses. Sequential evaluation of this complex case is displayed along with pertinent differential diagnoses for optic disc oedema and a review of current standards for diagnosis and management of papilloedema from dural sinus thrombosis.

“…Subfalcine herniation can lead to compression of anterior cerebral artery and result in infarction in unilateral, contralateral or bilateral anterior cerebral artery distribution. 20,21 Also, transtentorial herniation can compress the PCA and produce infarction in PCA distribution. 22,23 Although second surgery was performed immediately after CT scan, 1-hour interval was enough to bring the disaster to the injured brain.…”

A 40-year-old man suffered severe brain injury and received left side subdural hematoma evacuation with decompressive craniectomy. Intraoperative brain swelling had occurred during the surgery. Postoperative computed tomography (CT) scan was done immediately and showed a contralateral epidural hematoma resulting in herniation. Secondary hematoma evacuation was performed and found a linear fracture near a bleeding meningeal artery. 2 days later CT scan showed cerebral infarction mainly in right posterior cerebral artery distribution. Early diagnosis by postoperative CT scan or other potential ways such as intraoperative sonography is important to prompt treatments and interrupt the pathophysiological chain of the serial attacks.

“…In most cases, it is bilateral and results in symmetric obliteration of the perimesencephalic cisterns [ 15 ]. The vermis and medial portions of cerebellar hemispheres are pushed upward through the tentorial incisura leading to effacement of the superior vermian, ambient, and quadrigeminal cisterns and flattening and compression of the tectal plate and midbrain.…”

Cerebral herniation refers to the displacement of the brain tissues from their normal compartments into adjacent spaces, and are the most common secondary manifestation of any space-occupying intracranial mass regardless of its etiology. Several types of herniations have been described following anatomical basis (subfalcine, descending transtentorial, ascending transtentorial, transalar, and transcranial). The availability and speed of CT make it very useful in critically ill patients who may not tolerate either the wait for or duration of an MRI examination; however, MRI allows better characterization of brain herniations as well as early diagnosis of ischemic and hemorrhagic complications.
