Abnormal adenopathy along the inferior jugular chain may be due to metastatic disease from the supraglottic larynx, esophagus, or thyroid. Abnormal adenopathy in the midjugular chain may be related to metastasis from tongue, pharynx, or supraglottic larynx cancers. Those along the jugular digastric region are often related to metastasis from the pharynx, tonsil, tonsilar fossa, tongue, parotid gland, or supraglottic larynx. Submandibular adenopathy may be related to metastasis from adjacent skin, submaxillary gland, or base of the tongue. Posterior triangle nodes may be seen with metastasis from the pharynx, the nasopharynx, tongue base, tonsilar fossa, or thyroid.
Central necrosis makes lymph nodes suspicious for malignancy regardless of size.
Coronal CT is usually the most functional projection for evaluating the paranasal sinuses. A lesion placed at the osteomeatal complex can strategically obstruct the anterior sinuses. Concha Bullosum may act as an ethmoid air cell and should be reported. Usually well-rounded and arises from side wall of sinus. A mucus retention cyst represents an obstructed gland.
