TRACTION UPON INTRACRANIAL STRUCTURES
TRACTION UPON INTRACRANIAL STRUCTURES. An experimental model for clinical traction headaches is that the fleeting frontotemporal pain that will be induced in several traditional subjects by a sudden and vigorous rotary movement of the head. Such “jolt headache” has been shown to arise from traction by the brain because it abruptly shifts in position within the skull case.28 Experimental analysis indicates that jolt headache arises chiefly from tug upon the foremost arteries anchoring the brain at its base.
Intracranial Masses. Headache is common in patients with expanding intracranial lesions, whether these be tumors, subdural or intracerebral hematomas, or abscesses.

The pain is rarely intense or continuous, is aggravated by coughing or sudden straining, and in some patients is definitely accentuated or evoked by even mild head movement. It is erroneous to assume that such headache is caused merely by increased intracranial pressure, for experimentally made elevations of cerebrospinal fluid pressure in traditional human subjects consistently fail to supply headache.
Additional evidence indicates that when headache accompanies a brain tumor or alternative mass this symptom is typically attributable to sustained displacement of and traction on various sensitive structures, significantly the larger arteries of the brain stem, branches of the circle of Willis and veins that enter the foremost sinuses.ten In several instances the situation of the headache will be related directly to distortion of adjacent structures, as when pain is noted within the fronto-orbital area on the facet of a sphenoidal ridge meningioma, or when postauricular headache accompanies the expansion of a neuri-noma within the cerebellopontile angle. Less often, distant effects result from internal hydrocephalus caused by posterior fossa plenty occluding the aqueduct or fourth ventricle, for in such things headache is doubtless to be bifrontal and posterior. Headache may conjointly extend widely whenever expanding plenty manufacture gross displacement of the brain, leading to pressures upon the tentorium cerebelli, herniations at the incisura or foramen magnum, and distortion of multiple structures. In such things the headache loses all localizing diagnostic value.

The troublesome headache that thus often follows diagnostic lumbar puncture apparently involves a special form of traction.
Just like the headache that will be experimentally induced in a very seated subject by fast drainage of roughly twenty cc. of cerebrospinal fluid through a lumbar needle, it’s characteristically improved or abolished when the topic lies down.11 It will conjointly be relieved directly by the intrathecal injection of traditional saline answer, restoring cerebrospinal fluid volume. On the other hand, it’s typically accentuated by mild head jolt and, uniquely, by bilateral jugular compression. Accumulated knowledge from several sources suggest that, after lumbar puncture, fluid often leaks slowly through the dural- arachnoid hole into the epidural house, until closure begins by the deposition of fibrin or presumably by shifts in position of the meninges, occluding the opening by overlap.11 Whether or not this happens early or late is in half fortuitous and unrelated to whether the patient is kept abed or allowed up at once.
