Paradoxical Contralateral Herniation Detected by Pupillometry in Acute Syndrome of the Trephined.

Mil Med 2020 Mar;185(3-4):532-536

Walter Reed National Military Medical Center, Division of Neurosurgery, 8901 Rockville Pike, Bethesda, MD 20814.

Severe traumatic brain injury has historically been a non-survivable injury. Recent advances in neurosurgical care, however, have demonstrated that these patients not only can survive, but they also can recover functionally when they undergo appropriate cerebral decompression within hours of injury. At the present, general surgeons are deployed further forward than neurosurgeons (Role 2 compared to Role 3) and have been provided with guidelines that stipulate conditions where they may have to perform decompressive craniectomies.

Contralateral Ventriculostomy for Intraoperative Brain Relaxation in Supratentorial Brain Tumors.

Neurol India 2020 Jan-Feb;68(1):159-162

Department of Neurosurgery, All India Institute of Medical Sciences, New Delhi, India.

Background: CSF drainage from the ventricular system is a popular and effective technique for intraoperative brain relaxation as it reduces ICP, enlarges extra-axial operative corridors, and slackens the brain increasing its tolerance for surgical manipulation. However, sometimes when the ventricular chambers distant from the site of pathology are tapped, there is a risk of neurological worsening due to paradoxical herniation of the brain, exemplified by the phenomenon of upward transtentorial herniation observed in posterior fossa tumors, consequent to a supratentorial ventriculostomy. Expectation of an analogous phenomenon precludes contralateral ventricular drainage in supratentorial brain tumors producing midline shift, subfalcine herniation, and resultant distension of the opposite lateral ventricles.

Pseudohypoxic Brain Swelling: Report of 2 Cases and Introduction of the Lentiform Rim Sign as Potential MRI Marker.

World Neurosurg 2020 Jan 10;133:221-226. Epub 2019 Oct 10.

Department of Radiology and Interventional Neuroradiology, Isfahan University of Medical Sciences, Isfahan, Iran.

Background: A rare but important complication related to otherwise uneventful brain and spine surgery is becoming more recognized and more frequently reported in the medical literature. This has been variably labeled as pseudohypoxic brain swelling or postoperative hypotension-associated venous congestion. This poorly understood condition occurs in the setting of surgical intervention and is thought to be related to cerebrospinal fluid leak or evacuation, decreased intracranial pressure, and subsequent development of deep venous congestion affecting the basal ganglia, thalami, and cerebellum.

Traumatic Brain Injury: Imaging Patterns and Complications.

Radiographics 2019 10;39(6):1571-1595

From the Department of Radiology, Weill Cornell Medicine/New York-Presbyterian Hospital, 525 E 68th St, Starr 630C, New York, NY 10075 (A.D.S., S.N.N., A.J.T.); and Department of Radiology, Wake Forest School of Medicine, Winston-Salem, N.C. (C.T.W.).

While the diagnosis of traumatic brain injury (TBI) is a clinical decision, neuroimaging remains vital for guiding management on the basis of identification of intracranial pathologic conditions. CT is the mainstay of imaging of acute TBI for both initial triage and follow-up, as it is fast and accurate in detecting both primary and secondary injuries that require neurosurgical intervention. MRI is more sensitive for the detection of certain intracranial injuries (eg, axonal injuries) and blood products 24-48 hours after injury, but it has limitations (eg, speed, accessibility, sensitivity to motion, and cost).

Radiographics 2019 10;39(6):1598-1610

From the Department of Radiology, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Vasco de Quiroga 15, Mexico City, Mexico 14080 (B.R.G., A.C.H.V., J.A.G.M., O.C.R.R., R.C.A., M.D.L.M.M., J.A.H.C.); and Department of Neuroradiology, Instituto Nacional de Neurología y Neurocirugía Manuel Velasco Suárez, Mexico City, Mexico (J.I.M.L.).

Cerebral herniation, defined as a shift of cerebral tissue from its normal location into an adjacent space, is a life-threatening condition that requires prompt diagnosis. The imaging spectrum can range from subtle changes to clear displacement of brain structures. For radiologists, it is fundamental to be familiar with the different imaging findings of the various subtypes of brain herniation. Read More
