Abstract
Background
Giant ectopic mediastinal parathyroid adenoma with cystic degeneration and intratumoral hemorrhage is extremely rare, with low morbidity and a high misdiagnosis rate, and requires precise positioning and surgical resection. Case presentation: A 41-year-old woman presented with a sore throat for 3 days and hoarse voice for 1 day. The following chest computed tomography (CT) showed a large fusiform high-density mass in the posterior tracheal space (maximum cross-section of 34 x 25 mm). ultrasonography of the neck showed a low-echo solid mass. This patient had undergone 2 puncture treatments and 1 surgical treatment from the discovery of the lesion to the diagnosis of the cause over the span of more than a month. Subsequently, the final pathology was definitely diagnosed as parathyroid adenoma with cystic lesions. Six months after the operation, the patient did not relapse.
Conclusions
This case reported a rare and huge ectopic mediastinal parathyroid adenoma that was misdiagnosed as mediastinal tumor hemorrhage at an early stage. For ectopic mediastinal parathyroid adenomas, surgery is the preferred treatment option. Warn us that we should expand the scope of disease thinking for mediastinal tumors.
