ULTRASONIC EVALUATION OF CERVICAL LYMPH NODE METASTASIS OF SQUAMOUS CELL CARCINOMA IN ORAL CAVITY

Forty-four patients with oral cancer were examined by ultrasonography to detect cervical lymph nodal metastases. The lymph nodes, which were histopathologically or clinically confirmed to have cancer metastases, showed the following characteristic echogram findings: distinctive nodal boundary, posterior echo enhancement and an increased ratio of the shortest and the longest diameters of the node.It is suggested that these three peculiar ultrasonographic findings are considered to be important items for the differential diagnosis of benign nodes from the cervical metastasis of oral cance

ULTRASONIC DIAGNOSIS OF ORAL AND NECK MALIGNANT LYMPHOMA

A series of 14 patients with nodal and extranodal non-Hodgkin’s lymphoma of the oral and neck region was analyzed by ultrasonogram evaluation. Eight nodal lymphomas and six extranodal lymphomas commonly exhibited almost completely similar ultrasonographic findings, specifically, clear delineation of the boundary echo and a homogeneous, weak internal echo, the so-called pseudo-liquid-like images. The results derived from our study suggest that ultrasonic diagnosis is also helpful in evaluating patients with lymphoma during the initial diagnosis and initial treatment like other diagnostic imaging modalities
