FIGURE 2.

Cerebrospinal fluid rhinorrhea was present after brain trauma in a male patient of 37 year old. CT scan showed multiple basilar skull fracture. Thin layer scan of high-resolution CT showed that frontal sinus communicated with nasal cavity and cerebrospinal leak in frontal sinus was the diagnosis (A, coronal view; B, sagittal view). The surgical exploration confirmed that frontal sinus was impaired and communicated with intracalvarium and rhinorrhea disappeared after the surgical repair.
