Differential Diagnosis for Patient with Head Injury

The patient's symptoms following a fall from a left lift bar and hitting his head suggest a range of possible diagnoses. Here's a categorized differential diagnosis:

• Single Most Likely Diagnosis

  • Concussion: This is the most likely diagnosis given the patient's symptoms of headache, dizziness, mild blurred vision, sensitivity to noise, not feeling sharp, and mild fatigue after a head injury. These symptoms are classic for a concussion, which is a type of traumatic brain injury caused by a blow to the head or body, a fall, or another injury that jars or shakes the brain inside the skull.

• Other Likely Diagnoses

  • Post-concussive syndrome: While similar to concussion, post-concussive syndrome refers to a set of symptoms that can last for weeks or even months after the initial injury. The patient's current symptoms could be the beginning of this syndrome.
  • Cervical strain or whiplash: The fall could also have caused injury to the neck, leading to strain or whiplash, which might contribute to some of the patient's symptoms like headache and dizziness.
  • Skull fracture: Although less likely without more severe symptoms, a skull fracture is a possibility, especially if the patient hit his head with significant force.

• Do Not Miss Diagnoses

  • Epidural hematoma: This is a potentially life-threatening condition where bleeding occurs between the skull and the dura (the outermost membrane covering the brain). Symptoms can initially be similar to those of a concussion but can rapidly worsen.
  • Subdural hematoma: Similar to an epidural hematoma, a subdural hematoma involves bleeding beneath the dura, which can compress the brain and lead to severe symptoms or death if not promptly treated.
  • Subarachnoid hemorrhage: Bleeding into the space surrounding the brain (the subarachnoid space) can cause sudden, severe headache, and other symptoms similar to those the patient is experiencing.

• Rare Diagnoses

  • Diffuse axonal injury: A type of brain injury caused by shearing forces that occur when the brain rapidly accelerates or decelerates, typically seen in high-speed car accidents or severe falls. Symptoms can be similar to those of a concussion but may be more severe.
  • Second impact syndrome: A rare condition that occurs when an individual suffers a second concussion before the symptoms of the first have fully resolved, leading to severe and potentially fatal brain swelling.
