The great auricular nerve (GAN) is a sensory branch of the cervical plexus originating from the C2 and C3 nerve roots that innervates the external ear, mandibular angle, and parotid gland. Since idiopathic GAN neuralgia is a rare condition and branches of the GAN overlap with other cervical and cranial nerves, its diagnosis is challenging and can be confused with other facial neuralgias. This article describes the case of a 55-year-old woman with intractable unilateral periauricular and lateral head pain. No significant findings were found on cervical and brain imaging...

Cluster headache (CH) is a rare trigeminal autonomic cephalalgia. Although its pathophysiology is not entirely understood, the hypothalamus and trigeminal nociceptive and autonomic pathways seem to play a key role in its pathology. In the majority of cases, CH begins at a young age and affects mainly men. This article presents a case of a 76-year-old woman with CH that developed at the age of 74. This is one of the first documented reports of CH with such atypical features from an epidemiologic point of view...
