[Cysts and cystoid formations of the neck: significance and possibilities of radiodiagnosis].

The differential diagnosis of lateral cysts of the neck, metastatically altered lymph nodes and malignant tumors sometimes is difficult because their X-ray images as well as their clinical manifestations can be alike. The data of examination of 55 patients were analyzed. They included 43 cases of cysts of the neck (26 lateral and 17 median), 10 cases of cystically altered metastases into the lymph nodes, 2 cases of malignant tumors.

[Neck mass changes of the nontumorous and noninflammatory nature: the value of radiodiagnosis].

The results of X-ray examination of 25 (2.8%) out of 899 patients were analyzed. The changes of their neck mass were due to the conditions of non-tumoral and non-inflammatory nature.

[Neck tumors: possible reasons for radiologic misdiagnosis].

Neck tumors may be caused by a variety of both inflammatory and non-inflammatory lesions in organs and tissues. US and CT are successfully used to detect neck pathology but misdiagnosis still occurs. To analyze the situation, the data on 124 patients with tumors, cysts, inflammatory lesions and metastasis (after surgery and radiotherapy) were evaluated.

[Radiologic diagnosis of outside-of-organs neck neoplasms].

To evaluate the efficiency of ultrasound (US) and computed tomography (CT) in diagnosis of neck neoplasms, 36 patients with 26 benign and 8 malignant tumors were examined. Also, 32 US-guided fine needle aspiration biopsies (FNAB) were performed. Both US and CT showed high efficiency in detecting neck masses but not in different diagnosis, except for lymphomas.

[Radiodiagnosis of salivary gland neoplasia].

To evaluate the effectiveness of ultrasound (US) and computed tomography (CT) in diagnosing salivary gland neoplasms, 99 patients (benign tumor--72; salivary cyst--4 and malignant tumor--23) were examined. Also, 84 ultrasound-guided fine-needle aspiration biopsies were performed. Both US and CT showed high diagnostic potential in dealing with bulky lesions of the glands.

[Comprehensive radiologic examination in the diagnosis of parotid salivary gland diseases].

Comprehensive x-ray, ultrasonic and radionuclide examinations of 131 patients with chronic sialadenitis (n = 50), sialosis (n = 59), sialolithiasis (n = 9), autoimmune disorders (n = 6), and bulky processes (n = 7) of the parotid salivary glands were carried out. The diagnostic potentialities of each method in every of these conditions were analyzed. No correlation between the structural and functional disorders of the parotid glands could be traced.
