Magnetic
resonance imaging of pineal region tumours. Germinoma in a 12-month-old girl. Poorly-lobulated mass arising from the pineal gland (arrow), which has intermediate to high signal on sagittal T1-weighted image (a) and axial T2-weighted image (b), and shows contrast enhancement on sagittal T1-weighted image (c). Disseminated tumour (arrowhead) is also seen in the lateral and third ventricles with prominent enhancement. The tumour shows no restricted diffusion (d). MR spectroscopy at 1.5 T using a single voxel (2 × 2 × 2 cm3) acquisition with PRESS demonstrates elevated choline peak (*) and slightly decreased NAA peak (**) (e). Corresponding T1-weighted image post contrast shows the location of the voxel around the lesion (f)

Pineal germinoma - Ganzer Fall bei Radiopaedia
Germinoma is a term that if unqualified, usually refers to a tumor of the brain but can also refer to similar tumors of other regions particularly the ovary and testis.
- dysgerminoma of the ovary
- seminoma of the testis
- CNS germinoma: see WHO classification of CNS tumors
All these tumors share similar histology but obviously have very different imaging manifestations and clinical presentation. They are therefore discussed separately.
