As 'space-occupying-lesions,' the tumors can reach 3 to 4 cm or more in size and infringe on the facial nerve (facial expression) and trigeminal nerve (facial sensation). Advanced hearing loss and spells of true vertigo may occur. Very large tumors are life-threatening when they press on the cerebellum or cause brainstem compression. Late ...
Chronic subdural hematomas have been known to be a familiar cause of Kernohan's notch. [7] MRIs have shown evidence of Kernohan's notch from patients with traumatic head injury that are related to acute space-occupying lesions such as subdural hematoma, epidural hematoma, depressed skull fracture, or spontaneous intracerebral hematoma.

Collier, however, was "unable to accept this explanation", his view being that since the sixth nerve emerges straight forward from the brain stem, whereas other cranial nerves emerge obliquely or transversely, it is more liable to the mechanical effects of backward brain stem displacement by intracranial space occupying lesions.

Pain relief creams can cause side effects, although these are generally mild and temporary. Some individuals may experience skin irritation like redness or itching. Rarely, allergic reactions may ...
Severely raised ICP, if caused by a unilateral space-occupying lesion (e.g. a hematoma) can result in midline shift, a dangerous sequela in which the brain moves toward one side as the result of massive swelling in a cerebral hemisphere. Midline shift can compress the ventricles and lead to hydrocephalus. [21]
Other secondary causes include space-occupying lesions, ankylosing spondylitis, rheumatoid arthritis, and Paget's disease. Less commonly, the cause of spinal stenosis may be present at birth as seen in achondroplasia, spina bifida, and certain mucopolysaccharidoses. [15]
The symptoms will mimic those of space-occupying lesions. [7] Blood-borne spread certainly occurs, presumably by crossing the blood–brain barrier, but a proportion of patients may get TB meningitis from rupture of a cortical focus in the brain; [8] an even smaller proportion get it from rupture of a bony focus in the spine. [9]
LOS ANGELES (AP) - Southern California doctors were bribed to prescribe a pain-relief concoction as part of a $25 million workers' compensation scam that inadvertently caused a baby's death ...
