Extracranial multiorgan metastasis from primary glioblastoma: A case report

BACKGROUND Glioblastonia has a high degree of malignancy and poor prognosis. It is common to have in situ recurrence and in racranial metastasis, while extracranial metastasis is rare, and extracranial multiorgan metastasis is extremely rare. We report a case of glioblastoma with extracrania multiorgan metastasis, which will strengthen clinicians attention to the extracranial metastasis of glioblastoma and its treatment. CASE SUMMARY A male patient visited our hospital for treatment of dizziness and headache. Magnetic resonance imaging of the brain revealed a space-occupying lesion in the right temporoparietal occipital region. Chest computed tomography and abdominal ultrasound were normal, and no space-occupying lesions were observed in other organs of the body. The patient underwent surgery and diagnosed with glioblastoma. Postoperative concurrent radiotherapy and chemotherapy were completed. During the follow-up, the tumor was found to ve metastasized to the scalp and neck, and a second tumor resection was performed. Postoperative follow-up revealed extracranial metastases to multiple extracranial organs including skull, scalp, ribs, spine, liver and lung. His family members refused further treatment, and requested only symptomatic treatment such as pain relief, and the patient died of systemic multiple organ failure. Survival time from diagnosis to death was 13 mo and from extracranial metastasis to death was 6 mo. CONCLUSION Glioblastoma extracranial metastasis is extremely rare, clinicians should always pay attention to its existence. The mechanism of glioblastoma extracranial metastasis is still unclear, and genetic and molecular studies are required.
