Аннотация
BACKGROUND: Small-cell carcinoma of the urinary bladder (SCCB) accounts for 1% of all bladder tumors. We present a rare case of hemorrhagic metastatic brain tumor from SCCB diagnosed by navigation-guided endoscopic biopsy.
CASE DESCRIPTION: A 76-year-old man presented with sudden onset of aphasia and right hemiplegia from 3 weeks previously. He had a medical history of prostate cancer and SCCB. Computed tomography showed a mixed density mass in the left basal ganglia. On magnetic resonance imaging, the mass showed mixed intensity in both T1-weighted images and T2-weighted images, suggesting subacute hemorrhage. The mass was partially enhanced with gadolinium. The patient underwent endoscopic hematoma evacuation and partial removal of the tumor. Histopathological diagnosis was neuroendocrine carcinoma, which was consistent with SCCB metastasis. After surgery, the patient underwent whole-brain radiation therapy of 30 Gy. His general condition gradually deteriorated, however, and he died 4 months after surgery.
CONCLUSION: Our patient had a rare case of brain metastasis derived from SCCB which presented with cerebral hemorrhage. Navigation-guided endoscopic biopsy was useful for the diagnostic sampling of deep localized brain tumors with hemorrhage.
