Objective To investigate the association between headache symptoms and disease activity in neurosarcoidosis.

Background Sarcoidosis is a multisystem inflammatory granulomatous disease. Neurologic involvement occurs in approximately 5-10% of patients with sarcoidosis. The diagnosis of neurosarcoidosis is challenging due to lack of sensitive and specific biomarkers. Headaches are reported as a symptom, but the association between headache with disease activity in neurosarcoidosis has not been investigated.

Design/Methods A retrospective review was performed by searching the patient database for ICD-10 diagnosis of neurosarcoidosis (n=20). Patients with probable (n=11) or definite (n=4) neurosarcoidosis based on the modified Zajicek criteria were included in the analysis. The information on presenting symptoms, prior migraine history, imaging findings, and treatment response was extracted from the medical records.

Results New-onset daily headaches were present in 67% (10/15) of patients and occurred before the onset of other neurologic symptoms. Headache features include unilateral/bilateral tension-like pain (70%; 7/10), retroorbital pain (30%; 3/10), and neck pain (30%; 3/10). The most common radiographic feature associated with headache was the presence of leptomeningeal enhancement and evidence of radiographic progression correlated with worsening headache (60%; 6/10). Traditional analgesic therapies for headaches provided only partial symptom relief in 40% (4/10) and no relief in the remaining patients. Treatment with corticosteroids led to completed resolution of symptoms in 30% (3/10) of patients and partial resolution in 70% (7/10) patients. Treatment with infliximab was associated with complete resolution of headache symptoms in all patients (5/5). Relapse of headache occurred in all patients (3/3) who stopped infliximab therapy and was associated with radiographic progression of leptomeningeal disease.

Conclusions New-onset daily headache is an early clinical sign of disease activity in neurosarcoidosis as evidenced by its association with leptomeningeal enhancement, improvement with immunosuppressive therapy, and relapse after treatment discontinuation.
