99mTC-MDP bone scanning in a subungual glomus tumour

A 37-year-old female patient with four months history of paroxysmal pain in the left index finger was referred to our department for 99mTC-MDP scintigraphy. Radiographic studies of the patient showed a lytic tumour in the distal phalanx of the left second finger compatible with a glomus tumour. The scan showed mild decreased activity in the blood pool phase and minimal increased activity on the delayed images. The patient underwent surgery and a glomus tumour was removed. To the extent of our knowledge, this is the first case of bone scan in a glomus tumour of the finger reported in the literature

99m Tc-Octreotide-Avid Brain Mass In A Patient With Poorly Differentiated Papillary Thyroid Carcinoma, Hope In Despair

Brain metastases of PTC are rare and occur in 0.1-5% of the patients, especially in the poorly differentiated types that usually fail to concentrate iodine. We present a rare case of PTC with probable brain metastasis in a 58-year-old woman with a history of poorly differentiated PTC that showed elevated Tg levels and no metastasis was detected in the whole-body iodine scan, despite the positive 99m Tc-octreotide scintigraphy. This imaging modality could be helpful as a diagnostic guide for radionuclide therapy with labeled somatostatin analogs in cases of thyroid carcinoma with elevated Tg levels and negative whole-body iodine scan
