Video-Assisted Mediastinoscopy Under Continuous Intraoperative Neuromonitoring for Surgical Management of an Ectopic Parathyroid Adenoma: A Case Report
Abstract
Extramedullary myeloma, a subgroup of multiple myeloma, is a rare condition characterised by extra-skeletal infiltration of clonal plasma cells. Although parathyroid adenoma’s co-morbidity with multiple myeloma is common, extramedullary myeloma, an ectopic parathyroid adenoma has not been reported in the literature. This is the first study in literature that presents extramedullary myeloma that infiltrated ectopic parathyroid adenoma in the mediastinum after multiple myeloma treatment. In its course of relapse, the extramedullary myeloma created mass effect and no laboratory findings were present due to its non-secretory nature.

Case study: a parathyroid tumor ectopic to the mediastinum. The diagnostic capabilities and advantages of the 99mТс-sestamibi SPECT/CT hybrid method in the preoperative localization of abnormally located parathyroma are demonstrated.
