Abstract Traumatic brain injury (TBI) is an important health issue with high
prevalence. The most common type of TBI is mild traumatic brain injury (MTBI).
MTBI is known as a condition with self-limited symptoms; however it could cause
some structural abnormalities of brain and become complicated. Visible structural
brain damage could have an important effect on recovery after MTBI but the
outcome is not fully understood. This study investigated the clinical course of
MTBI patients with the existence of contusion in computed tomography (CT)
imaging. Fifty patients with MTBI and simultaneous brain contusion in CT scan
were enrolled according to specific exclusion criteria in 14 month. Patients were
followed up for two weeks after their first arrival for neurosurgical
interventions, decreased level of consciousness and other neurological
complications. Presence of neurological symptoms increased duration of hospital
stay and number of CT scans. Forty-two percent of MTBI patients with contusion
did not have any objective neurological signs. Fifty percent returned to the
hospital with neurologic symptoms and signs. Leading causes were headache
followed by seizure and dizziness. Rehospitalization was increased in the
patients with altered level of consciousness. The size of brain contusion
increased in two patients without further need for neurosurgical intervention.
Contusion alone did not worsen the prognosis of patients in short term follow up
and did not cause neurosurgical interventions.
