Differential Diagnosis for 77-year-old Female Patient
Single Most Likely Diagnosis
- Subdural Hematoma: Given the patient's age, use of anticoagulants (Eliquis for A-fib), recent fall, and symptoms of weakness, this diagnosis is highly plausible. The fact that she hit her head and has been feeling weak since the fall increases the likelihood of a subdural hematoma.
Other Likely Diagnoses
- Cervical Fracture or Strain: The patient's neck pain radiating to her left shoulder after a fall suggests a possible cervical spine injury, which is common in elderly patients after falls.
- Musculoskeletal Injury (e.g., hip fracture): Although the patient landed on her left side and has a hematoma on her left leg, a musculoskeletal injury such as a hip fracture should be considered, especially given her age and the mechanism of injury.
- Intracranial Hemorrhage (other than subdural hematoma): Given the patient's anticoagulation therapy and the fall, other types of intracranial hemorrhages (e.g., intraparenchymal, epidural, or subarachnoid hemorrhage) are possible.
Do Not Miss Diagnoses
- Spinal Cord Injury: Although less likely, a spinal cord injury could present with neck pain and weakness, especially if the patient has a cervical spine fracture or dislocation. This diagnosis is critical to identify promptly to prevent further injury.
- Epidural Hematoma: This is a medical emergency that can present with neck pain and neurological deficits. Given the patient's use of anticoagulants and recent trauma, it's crucial not to miss this diagnosis.
- Cervical Vertebral Artery Dissection: This condition can occur after a fall and presents with neck pain and neurological symptoms. It's a critical diagnosis to consider due to the risk of stroke.
Rare Diagnoses
- Hemophilia or Other Bleeding Disorder Complications: Although the patient mentions a bleeding disorder, the specifics are unclear. Complications from hemophilia or other bleeding disorders could be considered, especially given her anticoagulation therapy and recent trauma.
- Osteoporotic Compression Fracture: While not directly related to the fall, the patient's age and possible osteoporosis could predispose her to compression fractures, which might present with back or neck pain.
