Widespread Intra-abdominal Carcinomatosis from a Rhabdoid Meningioma after Placement of a Ventriculoperitoneal Shunt: A Case Report and Review of the Literature

Rhabdoid Meningioma Metastases Cervical Lymph Nodes: A Rare Clinical Case Report and Treatment Outcome

Meningioma is the most common central nervous system tumor that usually behaves benignly and has a good prognosis after treatment with tumor gross resection and with or without adjuvant therapy. Malignancy in meningioma is very rare and extracranial metastasis to cervical lymph nodes is even rarer. We report a case of a 40-year-old woman diagnosed with metastatic rhabdoid meningioma. She had recurrent primary disease and metastasis to bilateral cervical lymph nodes. She previously had intracranial tumor twice resected. We also review relevant, previously published cases in the literature. I hope you find these suggestions helpful.

Abdominal Metastases of Intracranial Germ Cell Tumor Via Ventriculoperitoneal Shunt Detected by 18F-FDG PET/CT

Extraneural metastases of primary brain tumors are rare. Here, we provided a case of a 19-year-old man presenting with 2 intra-abdominal masses, who had a history of intracranial germ cell tumors and a ventriculoperitoneal shunt implanted in order to alleviate obstructive hydrocephalus. The intra-abdominal lesions showed intense FDG uptake and were confirmed to be germ cell tumors by postoperative histopathology. F-FDG PET scan could be useful in monitoring metastases of intracranial germ cell tumors via ventriculoperitoneal shunt.
