Diagnosis of Head Injury Patient Symptoms
Clinical Presentation Analysis
The patient presents with a combination of key factors:
- Age: 70 years old (elderly patients are more susceptible).
- Medication: On anticoagulants (increases risk of bleeding).
- Trauma: Minor head injury (often sufficient for slow bleeds in this population).
- Symptom Onset: Delayed by one month.
- Symptoms: Severe headache, slowly developing neurological signs.
Differential Diagnosis Reasoning
Let's evaluate the options based on the presentation:
- Extradural haematoma: Typically associated with significant trauma and rapid symptom onset (hours to days) due to arterial bleeding. This doesn't fit the one-month delay.
- Acute subdural haematoma: Usually follows moderate to severe trauma, with symptoms developing within hours to days. This is inconsistent with the slow, delayed onset.
- Chronic subdural haematoma: This diagnosis strongly correlates with the patient's profile. Minor trauma, especially in the elderly or those on anticoagulants, can lead to slow venous bleeding. The hematoma gradually expands over weeks to months, causing symptoms like headache and progressive neurological deficits. The one-month delay is characteristic.
- Subarachnoid haemorrhage: Typically presents with a sudden, severe ("thunderclap") headache, not a slowly developing one over a month.
Conclusion
The classic presentation of a minor head injury in an elderly patient on anticoagulants, followed by a month-long delay before the onset of headache and slowly progressive neurological signs, is highly suggestive of a Chronic subdural haematoma.
Important Questions from Brain & Nervous System Surgery
- In diffuse axonal injury all are true EXCEPT:
- A patient with suspected head injury is brought to the emergency following road traffic accident. At the time of examination, patient is conscious with GCS 14/15 and stable vitals. There is bleeding from right ear and CSF leak from nose. Bruising is present behind the right ear. The most probable clinical diagnosis in this patient is
- A comatose patient after sustaining severe head injury has been admitted in neurosurgical ICU. Which of the following parameters should ideally be maintained in this patient ?
