Introduction: The exploration of hyperparathyroidism has been a great progress in recent years thanks in particular to the 99mTc (Technetium) -MIBI (methoxy isobutyl isonitrile) parathyroid scintigraphy. The objective of our study is to demonstrate the contribution of ultrasound and 99mTc-MIBI scintigraphy in the exploration for primary hyperparathyroidism. Materials and methods: A retrospective study on 8 years between 2010 and 2017 of 26 cases of primary hyperparathyroidism labeled biologically. All our patients underwent a cervical ultrasonography and a 99mTc-MIBI parathyroid scintigraphy with a double phase acquisition of static images after administration of the radiotracer. Results: The average age of our patients was 49 years with a female predominance (sex ratio of 2,71). The sensitivity and accuracy of the MIBI scintigraphy was 90.47% and 84.6%, respectively, compared with 84.21% and 76.9% for cervical ultrasonography. The couple ultrasonography/ scintigraphy were more efficient with sensitivity and accuracy of 100%.Conclusion: 99mTc-MIBI scintigraphy is a reliable means in the diagnosis of localization and multifocality of parathyroid nodules, especially if it is coupled with ultrasonography; it allows targeted surgery with less risk of morbidity.
