Abstract
Intracranial hypotension (IH) is a treatable cause of persistent headaches. Persistent
cerebrospinal fluid (CSF) leak at a lumbar puncture (LP) site may cause IH. We present
postcontrast MRI of a patient with post-lumbar-puncture headache (LPHA) showing abnormal,
intense, diffuse, symmetric, contiguous dural-meningeal (pachymeningeal) enhancement
of the supratentorial and infratentorial intracranial dura, including convexities,
interhemispheric fissure, tentorium, and falx. MRI also showed abnormal dural venous
sinus enhancement, a new finding in LPHA, suggesting compensatory venous expansion.
Thus, IH and venodilatation may play a role in the development of LPHA.
