Abstract:
Paragangliomas, also described as ectopic pheochromocytomas are infrequent neuroectodermal neoplasms that could be found wherever paraganglionic tissue exists. We present a rare case of a manifold non-functional primary hepatic paraganglioma in a 71 years old female. The combination of structural computed tomography and magnetic resonance imaging and of a functional modality, octreotide scan supported diagnosis. The role of nuclear medicine is crucial because it may help to determine future treatment in cases where there is suspicion of this tumour. However it has certain limitations, largely related to the physiological radionuclidic biodistribution. This case is described because of its relative rarity and also to emphasize the need to be studied by multidisciplinary collaboration.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
