The underlying disorder may be low CSF volume. A history of trivial increase in intracranial pressure (eg, on vigorous coughing) is often elicited. In other cases a sudden drop in atmospheric pressure has occurred.
Postural headache resembling that of low CSF pressure has been reported after coitus. Such headache should be coded here because it is due to CSF leakage.

Lateral views of the thoracic spine acquired during digital subtraction myelography with the patient in the prone position. For temporal reference, the initial image is designated as time of (A) 0.0 second, and the subsequent images are at (B) 0.4 second, (C) 1.4 seconds, (D) 3.6 seconds, and (E) 11.2 seconds. Contrast is seen to progressively extend cephalad dependently within the thecal sac (black arrowheads). At T6–T7, the contrast slightly deviates dorsally because of mass effect on the dura by the caudal aspect of the epidural fluid collection (white arrowheads). Contrast focally extravasates through the ventral dural tear at T5–T6 (white arrow) into the epidural collection (black arrows). Contrast extends cephalad within both the thecal sac and the epidural collection. Ultimately, the epidural fluid collection becomes more dense (*) because of its smaller volume relative to the subarachnoid space.

Abstract
Í×Ìó
A 53-year-old woman with superficial siderosis underwent spinal MR imaging, which demonstrated a large cervicothoracic epidural fluid collection compatible with a CSF leak. Conventional and dynamic CT myelography failed to localize the dural tear because of rapid equilibration of myelographic contrast between the thecal sac and the extradural collection. The superior temporal resolution of digital subtraction myelography precisely localized the CSF leak preoperatively and led to the successful surgical correction of the dural tear.

SUMMARY: A 53-year-old woman with superficial siderosis underwent spinal MR imaging, which demonstrated a large cervicothoracic epidural fluid collection compatible with a CSF leak. Conventional and dynamic CT myelography failed to localize the dural tear because of rapid equilibration of myelographic contrast between the thecal sac and the extradural collection. The superior temporal resolution of digital subtraction myelography precisely localized the CSF leak preoperatively and led to the successful surgical correction of the dural tear.

One limitation of CT myelography to identify a CSF leak is temporal resolution. During the time elapsed from intrathecal contrast injection under fluoroscopy to acquisition of the CT images, equilibration of contrast between intradural and extradural CSF collections occurs. When the extradural CSF collection is large, localizing the responsible dural tear can be challenging as a result. Dynamic CT myelography has been used to overcome this problem1 but still has temporal limitations inherent to the volume of tissue that must be imaged. We describe the case of a patient in whom chronic bleeding from a thoracic dural tear was the presumptive cause of superficial siderosis. The site of the tear was not adequately defined by myelography, postmyelography CT, or dynamic CT myelography, but digital subtraction myelography provided accurate preoperative localization.
