Info
On SPECT images a region of high Tc-99m Sestamibi uptake within right hemithorax is seen.
There is a big calcified mass at the right anterior superior mediastinum with a vivid Tc-99m MIBI uptake.
There are multiple bone lytic masses in a background of heterogeneous increased bone attenuation.
Case Discussion
This is an unusual finding in a patient with long history of hyperparathyroidism - ectopic parathyroid tumour in the right superior prevascular mediastinum.
The lytic bone lesions are thought to be brown tumours.
Heterogeneous increased bone attenuation has not been explained.
