A Case Report of Traumatic Temporal Cephalocele by Erika Vento in TBSND - Juniper publishers
A 40-year-old male patient, hit by a car two years
ago, evolved with hypoacusis (hearing impairment) and tissue projecting
into the left external auditory canal, detected by otoscopic
examination.
A computed tomography revealed an oblique fracture of
the left temporal bone associated with hypoattenuation of the adjacent
cerebral parenchyma compatible with parenchymal contusion. Bone
discontinuity of the tympanic tegmen with the presence of hypo
attenuating material in the tympanic cavity and in the homolateral
mastoid cells was also observed, this being non-specific to the method.
Subsequently submitted to a magnetic resonance of the
skull, meningoencephalic content was distinguished within the tympanic
cavity from the middle cranial fossa/tympanic tegmen, representing
post-traumatic cephalocele.
