A retrospective review of the role of B-mode and color Doppler ultrasonography in the investigation of primary hyperparathyroidism: Features that differentiate benign from malignant lesions.

Purpose: To identify the variant features encountered in parathyroid abnormalities and document those suggesting malignant change.

Materials And Methods: Data were collected from a cohort of patients who underwent investigation for primary hyperparathyroidism over a 10-year period. Ultrasonographic features: shape, presence of calcification, cystic changes, heterogeneous echogenicity, vascularity, capsular thickening, local invasion, and vascularity were reviewed retrospectively and were used to correlate with final histological findings.

Lu-Dotatate therapy for the treatment of metastatic neuroendocrine tumours in a patient on haemodialysis-dosimetric considerations.

We report on a case of a 68-year-old female, currently a dialysis-dependant patient with disseminated metastatic neuroendocrine tumour, treated with Lu-Dotatate. As Lu-Dotatate is cleared predominantly by the kidneys, there are concerns regarding the treatment plan strategy to avoid increased radiation exposure compared with patients with normal renal function. For this purpose, personalized dosimetry was used to calculate the safe administered activity using whole-body scans.

Ultrasound features of malignancy in the preoperative diagnosis of parathyroid cancer: a retrospective analysis of parathyroid tumours larger than 15 mm.

Objective: Nearly all reported parathyroid cancers are >15 mm at presentation. The objective was to identify ultrasound criteria of malignancy in parathyroid lesions of >15 mm in size.

Materials And Methods: This study was approved by a local ethics committee.
