Traumatic brain injury (TBI) is an important health issue with high prevalence.
The most common type of TBI is mild TBI (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.
