Objective. Paraganglioma is a rare neuroendocrine tumor. When it is located in the neck, it is commonly misdiagnosed as other thyroid neoplasms.Case Report. We report a case of cervical paraganglioma in a 55-year-old female. Patient was admitted to our clinic with goiter and neck pain. Thyroid ultrasonography revealed a 20 mm solitary, heterogeneous nodule located in the upper pole of left thyroid lobe. Fine needle aspiration cytology was nondiagnostic. She underwent left lobectomy and histopathology showed paraganglioma.Discussion. Cervical paragangliomas should be considered in the differential diagnosis of thyroid nodules.

AbstractWe encountered a case of diffuse thyroid swelling after fine needle aspiration (dTSaFNA) cytology, and monitored the swelling by thyroid ultrasonography. The scan findings are reported. A 57-year-old female visited our hospital complaining of swelling in her anterior neck. She had a history of metal allergy and was not taking any medications. Because a solid cystic tumor was detected in the left thyroid lobe, we decided to perform fine-needle aspiration cytology (FNAC). When the second aspiration was performed with a 22G needle inserted into the nodule in the left lobe, the patient immediately complained of pain in her neck. Within 2 minutes, her anterior neck swelled up and ultrasonography showed vascular dilatation in the left thyroid lobe. Neck cooling with steroid injection was undertaken. However, over the next 5 minutes, the vascular dilatation also spread to the right lobe. About 15 minutes later, the vessels gradually became unclear, and the neck pain and swelling persisted, and the patient was hospitalized for observation. By the following day, all the symptoms and signs had resolved and the patient was discharged. FNA is associated with the risk of neck swelling caused by hemorrhage or dTSaFNA. To make a prompt diagnosis and provide appropriate treatment for this complication, ultrasonography could be useful.

Needle Aspiration Cytology

The results of 1886 fine-needle cytoaspirations of solid, palpable thyroid nodules, « cold » on scintiscanning, performed between 1 January 1978 and 31 December 1986, were analyzed. In total 36 diagnoses of malignancy were made (1.9%). The results of cytologic and histologic examinations were compared in 114 cases to verify the diagnostic accuracy of this method; there was agreement in 98 cases and discordance in 16 consisting of 13 false negatives (11.4%) and 3 false positives (2.6 %). The sensitivity was 77.9 %, specificity 94.5 %, positive predictive value 93.8 %, negative predictive value 80 % and test efficiency 86 %. These values are in the range of those reported in the literature and confirm the validity of fine-needle aspiration cytology in the preoperative diagnosis of thyroid neoplasms.

Objective: Although fine needle aspiration cytology (FNAC) is the most reliable, safe and accurate method for the clinical management of abnormal thyroid nodules, 5%-15% of cases lead to indeterminate diagnoses and surgery is the recommended practice for them as they may be malignant. Nevertheless, the majority of cases with indeterminate cytology are benign, so the risk of unnecessary surgery is significant. In our study we combined FNAC and scintigraphy in order to reduce the number of inappropriate surgeries. Subjects and Methods: From 219 patients with thyroid fine needle aspiration cytology 33(9 males and 24 females) aged 18-73 years, had indeterminate FNAC diagnoses and were referred for scintigraphy. Surgery was performed in all cases. The results of FNAC, scintigraphy and histology were collected and compared. Results: From 33 cases with indeterminate cytology 32 had a benign histological diagnosis and only one was malignant (follicular Ca). That case had a positive scan. All cases with negative thyroid scans (29/33) were benign. False positive scans were 3, whereas one scan was true positive with final diagnosis follicular carcinoma. Conclusion: This study showed that combining the FNAC with the thyroid scintigraphy in cases of thyroid nodules with indeterminate cytology it is possible to reduce the number of inappropriate surgeries from 32 to 3.
