BACKGROUND AND PURPOSE The "polar vessel" sign has been previously described on sonography of parathyroid adenomas. We estimated the 4D CT prevalence of the polar vessel sign and determined features of parathyroid adenomas that are associated with this sign. MATERIALS AND METHODS Twenty-eight consecutive patients with parathyroid adenomas underwent 4D CT between 2008 and 2012 at 2 institution...

A case of squamous cell carcinoma ex pleomorphic adenoma in a palate is presented and comments on diagnostic criterias are described. The patient was 36-year-old male presenting with an ovoid elevated palate mass for 6 months. The tumor located in the junctional area of soft and hard palate. The mucosa was diffusely ulcerated and the mass focally tightly adherent to adjacent tissue. The initial...

introduction: the purpose of this study is to assess the integrated role of scintigraphy by tc99m mibi in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated spect study could be a complementary routine workup for patient with positive parathyroid adenoma on tc99m mibi parathyroid scan. methods: rest myocardium perfusion gated s...

A 19-year-old girl referred to our clinic complaining of a painless lump on the left side of her tongue.  The patient had no history of dysphagia, lingual paresthesia or bleeding. Physical examination revealed the presence of multiple enlarged lymph nodes on the left side of her neck.  Histopathology of lingual mass and lymph nodes showed pleomorphic adenoma.  To our knowledge, this is the firs...

a 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with loomci of iodine-131 and negative whole body scans was referred for follow up study. tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. the patient was operated, the parathyroid adenoma was removed. in thi...

concomitant papillary thyroid cancer and parathyroid adenoma is rare. we report a 55 years old female with papillary cancer admitted for surgery. preoperative laboratory findings revealed hypercalcemia and then primary hyperparathyroidism. thyroidectomy, neck dissection and excision of parathyroid adenoma were performed. histological examination revealed parathyroid adenoma. serum calcium retur...

A 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with lOOmCi of iodine-131 and negative whole body scans was referred for follow up study. Tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. The patient was operated, the parathyroid adenoma was removed. ...

Interest in risk factors for the recurrence of adenomatous polyps derives from the use of recurrent adenomas as surrogate end points in longitudinal studies of invasive colorectal cancer. In this case-control study, the effect of increased body mass index (BMI) on the risk of recurrent adenomas was investigated. Subjects consisted of patients seen at three colonoscopy practices in New York City...

Variation at the pleiomorphic adenoma gene 1 (PLAG1) locus has recently been implicated in the regulation of stature and weight in Bos taurus. Using a population of 942 outbred Holstein-Friesian dairy calves, we report confirmation of this effect, demonstrating strong association of early life body weight with PLAG1 genotype. Peripubertal body weight and growth rate were also significantly asso...
