cerebrospinal rhinorrhea [L, cerebrum, brain, spina, spine; Gk, rhis, nose, rhoia, flow] , a discharge of cerebrospinal fluid (CSF) from the nose. Basal skull fractures can transverse the paranasal air sinuses of the frontal bone, resulting in a dural tear. CSF can then leak through the dural tear and drain from the nose. Compare cerebrospinal otorrhea.
