A rare case

of laryngeal paraganglioma presenting as a neck mass. USG showed an iso to hypoechoic lesion with well circumscribed borders on the left side of the neck.

A diagnostic

approach to the mediastinal masses. Aortopulmonary paraganglioma in a 52-year-old woman. a Enhanced-CT scan shows a markedly enhancing lesion (arrow) located adjacent of the arch of aorta. b Image during the surgical remove of the lesion. Paraganglioma (white arrow); descending aorta (black arrow); vagus nervus (open arrow). c Photomicrograph demonstrated a trabecular pattern of growth and scattered ganglion-like cells surrounded by fibrovascular septa (arrows)

A rare case

of laryngeal paraganglioma presenting as a neck mass. Coronal contrast CT section shows the bilobed enhancing lesion with intra and extralaryngeal components

Anesthetic

management of a giant paraganglioma resection: a case report. A, contrast-enhanced MRI scan showing a heterogenous mass of 11 cm in diameter in the right retroperitoneal region (arrows). B, contrast-enhanced MRI scan showing the giant mass pressing against the surrounding blood vessels; only the abdominal aorta is clearly visible (arrows); an axial view

A rare case

of laryngeal paraganglioma presenting as a neck mass. Axial contrast CT section at the level of C4 vertebra shows an intensely enhancing bilobed lesion with intralaryngeal component in the pre-epiglottic fat and extralaryngeal extension through thyrohyoid membrane.

A rare case

of laryngeal paraganglioma presenting as a neck mass. Axial T1 section shows an isointense lesion with intra and extralaryngeal components.

A rare case

of laryngeal paraganglioma presenting as a neck mass. Axial T2 section shows a hyperintense lesion containing a few flow voids.

Glomus tumor

of the duodenum: a rare case report. Dynamic computed tomography (CT) shows a circumscribed tumor measuring 26 mm in diameter with ulceration in the second portion of the duodenum. a, b On arterial (a) and portal phase (b) of contrast-enhanced CT, the mass reveals significant enhancement. c The mass shows persistent enhancement on the delay phase

Glomus tumor

of the duodenum: a rare case report. a The tumor revealed hypo-intensity on T1-weighted image. b The tumor shows a modestly high intensity on T2-weighted imaging. c The tumor shows a slightly high intensity on diffusion-weighted images
