Trigeminal Neuralgia As the Principal Manifestation of Anaplasmosis: A Case Report.

Unlike the tick-borne diseases ehrlichiosis and Lyme disease, human granulocytic anaplasmosis is rarely associated with neurological complications. In this case report, we present a patient who developed a severe, lancinating headache shortly after known tick exposure. A tick-borne PCR panel was positive for and neurology evaluation yielded a concomitant diagnosis of new-onset trigeminal neuralgia. Our case explores the relationship between anaplasmosis infection and trigeminal neuralgia.
