Normal CT, Real Concussion: A Tampa Bay Guide for PI Teams

Why a normal head CT after a Tampa Bay crash does not rule out concussion, and which gaps in the medical timeline PI teams most often see.

It is one of the most common files on a Tampa Bay personal injury desk. A client is taken from a crash on I-275 or at the I-4/I-75 interchange near Brandon to a local emergency department. The head CT is read as normal, the discharge papers say neck strain, and the client goes home. Three weeks later the same client describes headaches, lost words, missed appointments and short-tempered evenings. The normal CT then becomes the first thing anyone points to.

This guide explains what that CT result does and does not mean medically, and where concussion records most often fall short. It is educational only and is not legal advice.

What a head CT is built to find

A head CT in the emergency department answers an urgent, narrow question: is there bleeding, swelling, a skull fracture or another injury that needs treatment right now? The National Institute of Neurological Disorders and Stroke (NINDS) at NIH describes CT as the test that shows skull fractures and brain bleeding, bruising or swelling. It also notes that MRI is more sensitive, and that currently available imaging and other clinical measures "can't always detect damage from mild, concussive injuries."

Concussion is diagnosed clinically, from the mechanism of injury, the person's signs and symptoms, and how the brain is functioning. A normal CT means the emergency team did not find a structural emergency. It is not a finding that no brain injury occurred.

What the research shows

In a TRACK-TBI pilot study published in Annals of Neurology (Yuh et al., 2013), adults with mild TBI who had a normal head CT received an MRI in the days that followed. About 27% of those CT-negative patients showed abnormalities on MRI, and certain MRI findings were linked with poorer function three months later. Imaging is only one part of the picture, but the study is a clear reminder that a clean CT is a limited answer.

Why this comes up so often in Tampa Bay

The volume is large. Florida's 2024 Traffic Crash Facts report counts 26,269 crashes and 17,359 injuries in Hillsborough County alone, with 7,075 crashes in Pasco, 2,616 in Hernando and 1,722 in Citrus. Many of those injured people are evaluated, scanned and released the same day, often after rear-end and merge crashes on I-275, the Selmon Expressway, Bruce B. Downs Boulevard and US-19. For people without a visible injury, head symptoms tend to surface later, at work or behind the wheel.

Gaps that weaken a concussion record

These are the patterns legal teams most often find when they read a Tampa Bay medical file:

• Emergency notes that document the neck and back in detail but say little about confusion, memory or how the person felt right after impact.
• A long gap between the crash and the first written mention of head symptoms.
• Symptoms that appear only in a family member's account, never in a clinician's note.
• No objective measure of brain function, so the record rests entirely on self-report.
• Symptom start dates that change from one provider's note to the next.

Florida's PIP statute adds a timing element worth knowing. Section 627.736 ties medical benefits to initial services received within 14 days after the crash, and the benefit limit depends on whether a physician, dentist, physician assistant or APRN determines an emergency medical condition. Early, accurate documentation by treating clinicians matters for reasons that go beyond the lawsuit.

Where objective testing fits

Testing decisions belong to the client's treating provider, such as a primary care physician, chiropractor, orthopedist or pain physician. When that provider decides objective testing makes sense, Braintree's mobile team performs concussion and TBI testing at the provider's office anywhere in Hillsborough, Pasco, Hernando and Citrus counties. Scheduling is coordinated with the referring provider.

The results become physician-reviewed diagnostic reports that go to the treating provider. Clinicians reach their own findings, and Braintree makes no promise about the outcome of any case. Learn more about concussion and TBI testing in Florida and mobile testing across Tampa Bay.

Court context

Hillsborough County cases are heard in Florida's Thirteenth Judicial Circuit. Pasco shares the Sixth Circuit with Pinellas, and Hernando and Citrus sit in the Fifth Circuit. Wherever a file ends up, the medical record will be read by people without a neurology background. Clear, dated, consistent clinical documentation helps everyone understand what happened to the client.
