“…Brewer and associates [44] studied the use of routine pre-operative ultrasound in 44 patients. They found a statistically significant decrease in operating time (from 135 minutes to 111 minutes) in the 25 patients who had true-positive ultrasound examinations, corn- (24,29,30) 0 (25,27,38) 0-5 (39--41) 0 (29, 39) e 2 (32,39) CT: computed tomography; MRI: magnetic resonance imaging. aSome sensitivities and false-positive rates have been recalculated from data supplied in the original references in order to permit comparisons.…”

“…Percutaneous aspiration, the simplest of these procedures, is usually the first performed if a tentative localization has been suggested by noninvasive tests. Ultrasound [25,[36][37][38][66][67][68], CT [25], and rarely even angiography [69], may be used for guidance. MRI may also be used for guidance, but is usually not employed due to considerations of cost and availability.…”

A variety of diagnostic tests are currently used for parathyroid localization. In patients who have not had previous surgery, none of these are as sensitive or specific for the localization of abnormal parathyroid glands as an experienced surgeon. In these patients, no pre-operative localization procedures are normally needed. Patients who have had previous thyroid or parathyroid surgery require pre-operative localization. Noninvasive imaging procedures (ultrasound, scintigraphy, computed tomography, magnetic resonance imaging) should be performed until an abnormal gland is identified in the same location on at least 2 examinations. The order in which these studies are performed is not important. In the 50% to 70% of patients in whom noninvasive studies are inconclusive, suspicious lesions may be aspirated or biopsied with imaging guidance. If this cannot be done or is nondiagnostic, angiography and, if necessary, parathyroid venous sampling should be done. Intra-operative ultrasound examination of the neck is helpful during re-operations. In selected patients, parathyroid tumors may be ablated by injection of contrast material through an angiographic catheter into the artery supplying the gland, or by percutaneous injection of alcohol into the gland itself. Angiographic ablation is best used for mediastinal glands supplied by the internal thoracic artery or by a descending branch of the inferior thyroid artery. Percutaneous alcohol injection may injure the recurrent laryngeal nerve permanently and should be limited to the rare patient with a neck lesion who has a prohibitive surgical risk. Neither technique is as effective as surgery.

“…Imaging methods are non-specific and invasive methods are often needed to establish an accurate diagnosis. Guided biopsies are accurate in diagnosing various pathologies, but cytologic interpretation of specimens from endocrine organs such as the parathyroids is problematical and the literature on parathyroid fine-needle aspiration (FNA) for cytologic and histologic analysis and parathormone assay is scanty and controversial (Solbiati et al, 1983;Rastad et al, 1984a;Mincione et al, 1985;Verbanck et al. 1986;Karstrup et al, 1987Karstrup et al, , 1989aBergenfelz et al, 1991).…”

Parathyroid adenomas: pre-operative localization with ultrasound combined with fine-needle biopsy

et al. 1993

Sixteen patients with biochemically proven primary hyperparathyroidism (PHPT) underwent ultrasonography (US), fine-needle aspiration (FNA) for cytologic sampling (n = 9), or intact parathormone assay (n = 3) before operation (n = 15) in order to determine the accuracy of the methods. Pre-operative US was found sensitive (100 per cent), but two thyroid lesions were initially diagnosed as parathyroid tumours by US (i.e. false positives). Parathyroid cells were detected in six cytologic specimens, one sample was insufficient and another inconclusive, while one was diagnosed as thyroid tissue. Parathormone assay revealed a high hormone content in all three patients who underwent the procedure. We conclude that US is sufficiently sensitive to detect enlarged parathyroid tumours. Specificity can be improved by US-guided FNA for cytology or parathormone assay prior to neck exploration.
