Abstract:
:Twenty-five patients with surgically and histologically proven squamous cell carcinoma of the palatine tonsil were studied with computed tomography (CT) using a high dose intravenous contrast enhancement technique. With this technique, CT demonstrated the primary carcinoma within the palatine fossa as well as its contiguous spread to the base of the tongue, mobile tongue, lateral pharyngeal wall, supraglottic larynx, and nasopharynx and metastasis to local deep cervical lymph nodes.

杂志文章abstract::Osteoid osteoma is a benign osteoblastic tumor usually diagnosed by conventional radiography. Computed tomography can be used preoperatively to localize the nidus and avoid unnecessary or misdirected resection. In this report CT appearance of the nidus in osteoid osteoma versus sequestration in osteomyelitis is presen...
