“…A Ultrasonographic studies of metastatic lymph nodes have not disclosed any characteristic patterns, and the diagnosis of metastasis has been based mainly on size. Size criteria of greater than 8 mm in transverse diameter,2 5 mm in diameter, 3 and 7 mm in thickness,• have been advocated, although the possibility for reactive hyperplasia to cause enlargement of lymph nodes has been noted. Bruneton et al 2 obtained 9% as the false positive rate caused by inflammatory swelling.…”

We investigated the location, size, and shape of cervical lymph nodes in head and neck cancer, using a 7.5-MHz ultrasound scanner. First, the different criteria for normal size were obtained for cervical lymph nodes in each region; lymph nodes greater than 9 mm in thickness in the internal jugular chain or greater than 7 mm in thickness in the submandibular and submental chains should be suspected of harboring metastatic foci. Second, meta· static nodes showed a more rounded configuration than A precise evaluation of the presence of meta· stasis to the cervical lymph nodes is mandatory in the management of head and neck malignancies. X-ray computed tomography (CT), 1 magnetic resonance imaging (MRI), and ultrasound 2 -4 have been used to evaluate lymphadenopathy in the neck. Recent reports on ultrasonography in the neck suggest its high efficiency in detecting small, nonpalpable lymphadenopathy. Although size has been used to diagnose me~ tastasis in lymph nodes, few studies have dealt with their internal structure.To determine the size and shape criteria for normal lymph nodes in each region in the neck, as well as to clarify any abnormal patterns of internal structure in metastatic lymph nodes, we conducted a correlative Received July 20, 1987, from the Departments of "Radiology, fOral Surgery. *Otolaryngology. and §Laboratory Medicine, School of Medi· cine, Shinshu University.

Third, a comparative study of metastatic lymph nodes between the in vivo and in vitro ultrasonograms and the corresponding histopathological findings disclosed that an echogenic region in an ultrasonogram of a metastatic node was caused by coagulation necrosis, and a cystic area of liquefaction necrosis.

“…2 Although lymph node biopsy is the final method* to differentiate between benign and malignant nodes, several investigations are known to be helpful, including ultrasound and CT of nodes. 3,4 In this study, by reviewing the histopathological results of 220 lymph node biopsies and correlating the result with clinical findings and simple investigations, we attempted to develop a model predicting nodal malignancy from the age and sex of the patient, consistency of lymph node, result of Mantoux test and abdominal ultrasound.…”

A Logistic Regression Model to Predict Nodal Malignancy among Cases With Lymphadenopathy

Background: Peripheral lymphadenopathy can be caused by benign and malignant diseases. In this logistic regression model, we attempted to identify the clinical findings predicting high probability of nodal malignancy. Materials and Methods: Two hundred and twenty cases diagnosed by peripheral lymph node biopsy were studied. Of these, 164 had benign lymph node pathology, while the other 56 were malignant. The patients' medical charts were reviewed and a logistic regression model used to identify physical signs and simple investigations that will predict nodal malignancy. Results: Hard lymph node consistency, negative Mantoux test and positive abdominal ultrasound (showing hepatosplenomegaly with or without lymphadenopathy) were found to correlate with a higher probability of nodal malignancy. Conclusion: A logistic regression model is proposed to calculate the probability of lymph node malignancy at different ages and both sexes in relation to lymph node consistency, Mantoux test and abdominal ultrasound results.

Maxillofacial surgery, like any other surgical specialty is greatly dependent on the discipline of radiology. This poses a greater challenge because of the complex anatomy of this region. Various investigation modalities have been applied in diagnosing various diseases which are found in the maxillofacial region, including IOPA, PET, USG, CT, MRI and panoramic radiographs. Of these, USG can easily diagnose non invasive and soft tissue diseases. It is very useful in diagnosing the diseases which are not usually evident on a conventional radiograph. However; many of the dentists are not aware of the benefits of USG in diagnosis of oral diseases. In this article, the use of ultrasound in diagnosing the various pathologies of maxillofacial region is elaborated.
