“…7 Metastases from GM may follow cerebrospinal fluid (CSF) diversion, 2,9 or vascular tumor invasion within the CNS. 10 In addition, the malignant cells may gain access to the extrameningeal tissue as a result of spontaneous perforation of the dura 11,12 or dura and bone, 13 but most frequently, as in our case, it follows a craniotomy. 3 The mechanism by which surgery predisposes to metastasis from GM is not fully determined.…”

“…The most plausible explanation is that during the surgical procedure the extrameningeal tissues are exposed to dislodged neoplastic cells which are capable of invading the lymphatics and extradural vasculture. 5,11 This process may continue in the postoperative period if the dura is left open. 3 In addition, it has been suggested that the postoperative reparative processes may generate new capillaries with fragile walls that are susceptible to invasion.…”

“…A 1970 review by Anzil showed that there was no documented surgical intervention in more than 10% of patients with metastatic glioblastoma [12]. In these cases, the mechanism of extra-cranial spread is not fully understood.…”

“…Invasion of the dural veins is seen in most cases of extracranial metastases from glioblastoma in patients who did not undergo craniotomy. 1,12,17) Spontaneous extracranial metastases might be expected in patients with tumors attached to and invading the dura, 4) such as two cases of the transdural extension of gliomas. 11) Direct contact between the tumor and the basal dura, intracranial hypertension, structural weakness, and surgery can allow tumor cells to migrate through the dura.…”

“…Metastases from glioblastoma occur in the lung, lymph nodes, 9,14) bone, 1,2,5) bone marrow, 6) and liver. Metastasis to the spleen is extremely rare, with only three cases reported.…”
