Summary
This study highlights how initial spinal imaging may misdiagnose gliosis as malignancy. Positron emission tomography (PET) scans can show pseudoprogression, requiring careful interpretation to avoid unnecessary treatments.
Area of Science:
- Neuroscience
- Radiology
- Oncology
Background:
- A 60-year-old woman experienced left upper limb weakness, prompting an initial spinal MRI.
- The initial MRI identified a C2-C3 heterogeneous mass, which showed no abnormal activity on 18F-FDG PET scans.
- Surgical resection revealed gliosis, not malignancy, but the patient's symptoms persisted and worsened.

117
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...

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
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...
