We report a case of breast cancer detected as an incidental finding on 99mTc-MIBI scintigraphy. 99mTc-MIBI scintigraphy is usually used to evaluate cardiac perfusion or to detect ectopic parathyroid adenomas; however, it is also known to sensitively detect breast cancer. Accordingly, a few reports have described the incidental detection of breast cancer by 99mTc-MIBI scintigraphy performed to detect parathyroid adenoma. Our present case underscores the importance of attending to any incidental findings when searching for parathyroid adenomas using 99mTc-MIBI scintigraphy.

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.

Detect Breast Cancer

A survey to detect breast cancer in well women volunteers by clinical and mammographic techniques is described. Nine hundred and twelve such volunteers were examined by both methods and no carcinoma was found. One patient however presented 18 months later with a small palpable carcinoma. The reasons for the failure to detect significant disease are discussed and the incidental findings recorded. It is suggested that at the present time such surveys yield too little benefit to justify the work and expense entailed. Future developments in technique by reducing the cost might make such schemes more feasible hut at present they should be confine***d to screen certain ‘high risk’ populations.

Increased Activity

During routine blood work, a 53-year-old female patient was noted to have asymptomatic hypercalcemia and subsequently found to have hyperparathyroidism. Localization studies for a suspected parathyroid adenoma included 99mTc Sestamibi scintigraphy, Single Photon Emission Computed Tomography (SPECT)/computed tomography (CT) study, and ultrasound of the neck, which were initially read as negative for parathyroid adenoma. A contrast-enhanced CT scan of the neck was performed to locate the suspected parathyroid adenoma and demonstrated a soft tissue lesion within the right piriform sinus. Flexible fiber optic nasolaryngoscopy revealed a submucosal lesion in the right piriform sinus. Following these findings, the initial 99mTc Sestamibi scintigraphy and SPECT/CT were reviewed with confirmation of a focal area of increased activity superior to the right thyroid lobe, corresponding to a nodule in the right piriform sinus that demonstrated increased activity on SPECT/CT. The patient was brought to the operating room for surgical management where a laryngoscope and operating microscope were utilized. The encapsulated lesion was dissected and excised in total. The parathyroid hormone and ionized calcium levels normalized postoperatively. Pathology confirmed a parathyroid adenoma. Parathyroid adenomas are the most common cause of primary hyperparathyroidism. Sixteen percent of parathyroid adenomas can be situated in an ectopic location. Ectopic parathyroid adenomas in the piriform sinus are rare with only a few previously documented cases. We document a rare case of ectopic parathyroid adenoma in the piriform sinus overlooked on initial imaging studies. These lesions can be challenging to localize, however, an understanding of embryology, close scrutiny of possible ectopic locations, and the application of complementary imaging techniques may prove useful for surgeons and clinicians.
