Summary
Multiple intracranial germinomas, initially found in the basal ganglia and corpus callosum, were likely metastases from a primary pineal germinoma. This highlights the importance of ruling out primary lesions in unusual locations.
Area of Science:
- Neuro-oncology
- Neurosurgery
- Radiology
Background:
- Intracranial germinomas are rare tumors, typically arising in the pineal or suprasellar regions.
- Multiple intracranial germinomas in unusual locations are infrequently reported, posing diagnostic challenges.
Purpose of the Study:
- To present a case of multiple intracranial germinomas involving the basal ganglia and corpus callosum.
- To illustrate the clinical and neuroradiological progression of these tumors.
- To emphasize the potential for metastatic spread from a primary pineal germinoma.
Main Methods:
- Clinical case presentation.
- Sequential neuroradiological imaging (e.g., MRI, CT).
- Pathological correlation (implied).
Main Results:
- A patient presented with multiple intracranial germinomas affecting the basal ganglia and corpus callosum.
- Radiological studies tracked the development and spread of the tumors over time.
- Findings indicated that these multiple lesions were secondary deposits from a primary pineal germinoma.
Conclusions:
- Multiple intracranial germinomas in atypical locations may represent metastases from a primary pineal germinoma.
- Thorough investigation for a primary pineal or suprasellar lesion is crucial in germ cell tumor cases presenting in unusual intracranial sites.

Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
