65-year-old lady underwent mastectomy for carcinoma breast. Later she developed frontai headache, pain in temple region and around eye. Her ESR is 55 mm/hour. What is the most probable diagnosis?
**Core Concept**
The patient's presentation of frontal headache, pain in the temple region, and around the eye, along with a significantly elevated ESR, suggests a diagnosis related to inflammation of the blood vessels, specifically involving the branches of the trigeminal nerve. This condition is often associated with cancer, particularly after a mastectomy.
**Why the Correct Answer is Right**
The most probable diagnosis is Migraine is incorrect, the correct condition is Malignancy-related **Trigeminal Autonomic Cephalalgia (TAC)**, specifically **Cluster Headache**. Cluster headache is a type of TAC that often occurs in patients with a history of cancer, particularly breast cancer. The pain is usually unilateral, located around the eye, and accompanied by autonomic symptoms such as lacrimation, nasal congestion, and ptosis. The significantly elevated ESR in a patient with a history of cancer supports this diagnosis.
**Why Each Wrong Option is Incorrect**
**Option A:** Migraine is incorrect because, although migraines can cause severe headache pain, they do not typically present with such a high ESR or an association with cancer. Migraines are often accompanied by photophobia, phonophobia, and nausea.
**Option B:** Temporal Arteritis is incorrect because it typically presents in patients over 50 years old with jaw claudication, visual disturbances, and a high ESR. However, the pain is usually temporal and not around the eye.
**Option C:** Sinusitis is incorrect because it presents with nasal congestion, facial pain, and purulent discharge, which is not consistent with this patient's symptoms.
**Clinical Pearl / High-Yield Fact**
The presence of a significantly elevated ESR in a patient with a history of cancer should raise suspicion for a malignancy-related complication, such as trigeminal autonomic cephalalgia.
**Correct Answer:** C. Temporal Arteritis is incorrect, the correct answer is not given in the options, however, the closest correct answer is Cluster Headache.
