Pneumocephalus (PC) is an uncommon and life-threatening neurological condition. Air within the ventricular system of the brain is also known as Pneumoventricle (PV). It requires emergency treatments to prevent catastrophic neurological outcomes. Head injury is the most common cause of PV, but there are other well-recognized etiologies in case there is no clear radiological evidence of skull discontinuity.

Objective: To evaluate olfactory function and clinical–neurological characteristics in a group of patients
with mild head trauma.
Methods: A total of 352 patients with MTBI underwent olfactory function evaluation. The site of head trauma,
loss of consciousness <20 min, memory loss, subjective presence or absence of olfaction and other clinical,
neurological and radiological aspects were evaluated and compared with the olfactory dysfunction.
Results: A total of 33.5% patients enrolled in the study had an olfactory dysfunction. Eighty-seven
