Differential Diagnosis for the 65-year-old Female with New-Onset Headaches
- Single most likely diagnosis:
- Tension headache: This is the most likely diagnosis given the description of "pressure" headaches, "heavy eyes," and worsening when leaning forward. The fact that it improves with Tylenol ES and occurs in the evenings also supports this diagnosis.
- Other Likely diagnoses:
- Migraine: Although the patient's headaches are not typically migrainous (no mention of unilateral pain, nausea, or photophobia), some migraine variants can present with bilateral pressure-like headaches.
- Cervicogenic headache: Given the worsening of symptoms when leaning forward, a cervicogenic cause should be considered, especially if there's any history of neck pain or trauma.
- Medication overuse headache: Although the patient is only taking Tylenol ES nightly, it's essential to consider the possibility of medication overuse headache, especially if the patient has been taking it regularly for an extended period.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
- Giant Cell Arteritis (GCA): This is a critical diagnosis to consider in patients over 50 with new-onset headaches, especially if there are any visual symptoms (e.g., "heavy eyes" could be interpreted as a visual disturbance). GCA can lead to blindness if not promptly treated.
- Subarachnoid hemorrhage or other intracranial hemorrhages: Although the patient's headaches are not typically "thunderclap," it's essential to consider the possibility of an intracranial hemorrhage, especially given the patient's history of hypertension.
- Brain tumor: A new-onset headache in a patient over 50 warrants consideration of a brain tumor, especially if there are any focal neurological deficits or worsening symptoms over time.
- Rare diagnoses:
- Temporal arteritis: Similar to GCA, temporal arteritis can cause headaches and visual disturbances, although it's less common.
- Idiopathic intracranial hypertension (IIH): This condition can cause headaches and visual disturbances, especially in patients with a history of obesity or other risk factors.
- Hypnic headache: This is a rare condition characterized by recurrent headaches that occur only during sleep, although the patient's headaches occur in the evenings, not exclusively during sleep.
