“…Nonfunctioning parathyroid cysts (PCs) are divided into two categories: functioning and nonfunctioning cysts. Nonfunctioning PCs are true cysts and usually asymptomatic, whereas large cysts can cause symptoms such as neck bulging, dysphasia, pain, tracheal compression, and recurrent laryngeal nerve palsy [ 14 , 40 - 42 ]. US-guided simple aspiration is the preferred technique for diagnosing nonfunctioning PCs [ 14 , 43 ].…”

Previously, radiologists played a limited role in the treatment of parathyroid disease, primary focusing on the preoperative localization of parathyroid lesions responsible for hyperparathyroidism. But, the widespread use of high-resolution ultrasound has lead to the increasing detection of parathyroid incidentalomas (PTIs). Consequently, radiologists may be required to differentiate PTIs from thyroid lesions, which is most reliably accomplished through the fine needle aspiration-parathyroid hormone analysis. Various nonsurgical treatment modalities for hyperfunctioning parathyroid lesions have been developed with some efficacy. Especially for symptomatic nonfunctioning parathyroid cysts, simple aspiration is a first-line procedure for diagnosis and treatment, while ethanol ablation is a subsequent treatment modality for recurrent cases.

“…The improvement in the impaired vocal cord mobility in response to surgical drainage in the setting of acute suppurative thyroiditis (20) supports the nerve-stretching hypothesis. Vocal cord paralysis complicating Riedel's thyroiditis (21) and parathyroid disease (22)(23) lends this hypothesis further support with stretching being the only possibly plausible explanation (21)(22)(23). The difference in time of onset of vocal paralysis in between focal disease (nodules) and diffuse disease (Graves) may be explained on this basis.…”

Laryngeal palsy occurs extremely rarely after radioiodine therapy for Graves' disease. We describe a case of complete right laryngeal paralysis in a 73 year old man who received two conventional doses of radioiodine (15 mCi) 9 months apart. He presented one day after the radioiodine therapy with loss of voice, discomfort in the right side of his neck, dry cough and throat irritation. The pain disappeared in a couple of weeks but the dysphonia persisted. Direct laryngoscopy confirmed complete right vocal cord paralysis and imaging excluded other regional pathology. His voice improved progressively to full recovery by six months though the vocal paralysis persisted even at 12 months of follow up. The case reminds physicians that radioiodine therapy for Graves' disease may rarely cause complications that need timely recognition and treatment.

“…[ 55 , 185 ] CT and MRI scan has nonspecific findings, but they can easily reveal homogenous areas of cystic nature and are useful tools for the diagnosis, especially when there is symptomatology of vocal cord paralysis or if the cyst is mediastinal. [ 45 , 47 , 54 , 55 , 58 , 117 , 131 , 148 , 166 , 167 , 186 – 188 ] The neck ultrasound examination is of great importance for the evaluation of PCs, as it reveals the cystic nature of the mass and its dimensions, is easily done and can be combined with FNA aspiration fluid. [ 3 , 21 , 44 , 50 , 69 , 131 , 143 , 148 , 151 , 168 , 171 , 185 – 187 , 189 – 194 ]…”

Background:Parathyroid cysts are lesions that represent 1–5% of neck masses. They are subdivided into two categories: functioning and non-functioning.The aim of the present review is to give a detailed account of all reported cases of parathyroid cysts in the literature and to analyze statistically the available data.Methods:A bibliographic research was performed from 1905 until 2016. A database with the patients’ characteristics was made and analyzed statistically.Results:A total of 218 articles were found, reporting 359 cases of cysts. Mean age of patients was 49.24 y/o and the male/female ratio was 1:1.85. The most common locations were left thyroid lobe (113/358 patients, 31.6%), and superior mediastinum (69/358 patients, 19.3%), while the most common symptoms were neck mass (148/355 patients, 41.7%), compressive symptoms (73/355 patients, 206%) and hyperparathyroidism (62/355 patients, 17.5%). Non-functioning cysts were more frequent (220/357 patients, 61.6%). Regarding dimensions, mean diameter was 4.88 cm. Ultrasound and FNA are used for their diagnosis, while cystic fluid analysis may help the differential diagnosis. Recurrences were mentioned in 27/97 patients (27.8%) with available data. No deaths due to parathyroid cysts were mentioned in the literature.Conclusion:Parathyroid cysts should be taken into consideration in case of parathyroid dysfunction or asymptomatic neck mass. The surgeon's careful manipulations on the cyst are crucial for a definitive treatment.
