Presentation
Head trauma.
Patient Data
Normal grey-white matter differentiation. Ventricles and sulcal pattern are within normal limits. Basal cisterns are unremarkable. No acute calvarial fracture identified.
Incidental note is made of a 12mm pineal cystic lesion. No convincing solid component, however given its size further imaging with MRI (pineal protocol with contrast) is recommended.
A pineal cyst is demonstrated measuring 12 x 8 x 11 mm with a thin (less than 1 mm) enhancing rim and a thin septum on the left side, but no nodule or solid component. It minimally distorts the tectal plate, without hydrocephalus. Flow void in the aqueduct is visible. Phase contrast imaging (SWI) confirms the presence of peripherally located calcification (on phase imaging the peripherally located calcium is black (opposite to blood in veins), thus enabling you to distinguish Ca+ from blood product).
