Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
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...

Background:

Askin tumour is a rare primitive neuroectodermal tumor of the chest wall.
It belongs to the Ewing family of tumors and typically presents with aggressive behavior.
Common symptoms include pain, dyspnea, and weight loss, often leading to misdiagnosis.

Purpose of the Study:

To present imaging findings of Askin tumour on Technetium-99m MDP bone scans.
To highlight the utility of bone scintigraphy in diagnosing this rare malignancy.

Main Methods:

Retrospective review of a few cases of Askin tumour.
Imaging analysis of Tc-99m MDP bone scans.

Main Results:

Demonstration of characteristic uptake patterns of Askin tumour on Tc-99m MDP bone scans.
Correlation of imaging findings with histopathology.

Conclusions:

Tc-99m MDP bone scan can be a valuable tool in the diagnostic workup of Askin tumour.
Early and accurate diagnosis through advanced imaging can facilitate timely multidisciplinary treatment.
