TIPIC-A Newly Recognized Syndrome: Multimodality Imaging of a Rare Clinicoradiological Entity.

Carotidynia is a controversial clinicopathological entity vastly described in Western literature as neck pain in the region of carotid bifurcation secondary to an underlying inflammatory etiology. Radiologically, this appears as perivascular inflammation and has recently been designated as transient perivascular inflammation of the carotid artery (TIPIC) syndrome. The authors of this report discuss the multimodality imaging features of a rare case of this disease in our country to familiarize radiologists with the imaging findings and to encourage the inclusion of TIPIC syndrome as a differential diagnosis for focal neck pain.

Primary skull base neuroendocrine carcinoma-a case report and review of literature.

Skull-based neuroendocrine carcinomas are rare tumors with only a few case reports in literature. Here we present an unusual case of primary neuroendocrine carcinoma of the skull in 60-year-old male which was proven on surgical biopsy. The imaging features of this rare tumor along with differential diagnosis are discussed with brief review of the literature.
