“…However, cases of TMM of occult lung malignant tumors have rarely been reported. [ 5 , 23 , 27 , 31 ] In our case, there were no preoperative symptoms of lung carcinoma except for an irregular mass on imaging examinations. Many authors have considered it difficult for clinicians to provide a specific preoperative diagnosis of TMM by imaging examination.…”

Rationale: Tumor-to-tumor metastasis is a rare clinical phenomenon. Although meningioma is the most common intracranial recipient of cancer metastasis, only a few cases have been reported. We present a case of metastasis of lung adenocarcinoma into intracranial meningioma and review the published literature. Patient concerns: A 70-year-old woman was admitted to our hospital for a 1-month history of headache and pain in her lower extremities. Diagnosis: Brain and lumbar vertebral magnetic resonance imaging showed an intracranial space-occupying lesion in the right occipital region and spinal canal stenosis. Pulmonary computed tomography showed an irregular mass in the right upper lobe of the lung. The postoperative histological examination demonstrated adenocarcinoma metastasis to meningioma. Intervention: The patient underwent right occipital craniotomy for tumor removal and lumbar spinal canal decompression. Outcomes: There were no initial abnormal conditions after the operation. However, the patient died suddenly 7 days after surgery. Lessons: Tumor-to-meningioma metastasis is a rare but important phenomenon. According to previous reports, it is associated with rapid onset of symptoms and a poor prognosis. Histological examination is of great importance in diagnosis. The history and process of malignant carcinoma should be closely monitored.

“…Specifically, meningiomas have been described as the most common intracranial tumor to host metastases [ 9 , 11 ]. Malignant cells from renal, prostate, hematopoietic, gastrointestinal, breast and lung tumors have been documented to metastasize into meningiomas, with breast and lung tumors to be the most common primary sites [ 9 , 12 , 13 ]. The Surveillance, Epidemiology, and End Results program indicates the incidence of primary breast tumors as 124.9 cases per 100,000, while the incidence of primary lung tumors as 55.8 cases per 100,000 [ 14 , 15 ].…”

Intracranial meningioma with carcinoma tumor-to-tumor metastasis: two case reports

et al. 2018

Meningiomas have been implicated as the most common primary intracranial tumor to contain tumor-to-tumor metastasis. In the following two case reports, we describe cases of adenocarcinoma and breast carcinoma that metastasized into an intracranial meningioma. The first patient was a 64-year-old man presenting to the emergency department with seizures and loss of consciousness. After a left frontal mass resection, pathology reported a heterogeneous mass consisting of a meningioma and a metastatic adenocarcinoma component. The second patient was a 63-year-old woman presenting with significant vision problems and unstable gait. After a right frontal mass resection, pathology reported a heterogeneous mass consisting of a meningioma and a metastatic breast carcinoma component. Possible explanations for the development of the tumor-to-tumor metastasis are described.
