Choriocarcinoma misdiagnosed as cerebral hemangioma: A case report

Figure 1 Pathological pictures of the patient showed infiltrating large and pleomorphic tumor cells into the brain parenchyma with extensive hemorrhage and necrosis. Hematoxylin and eosin stain, intermediate power.

Figure 2 The pictures of uterine artery angiograms for the patient. A, B: Selective uterine artery angiograms proved active bleeding of the branches of uterine arteries before operation (arrows); C-E: Hemorrhage of blood vessels was ceased immediately after selective embolization (arrows).

Figure 3 Diagram of curves of β-human chorionic gonadotropin level decreased with the course of chemotherapy. β-HCG: β-human chorionic gonadotropin.

Figure 4 Brain images of the patient before and after therapy. A: Brain computed tomography image of the patient before therapy indicated residual tumor at the brain operation area; B: Brain magnetic resonance image of the patient after treatment was significantly decreased compared with that before treatment and there was no sign of residual tumor.

Figure 5 Lung computed tomography images of the patient at different stages of treatment. A-C: Multiple nodules of bilateral pulmonary were shown on computed tomography (CT) image before chemotherapy (orange arrows, metastatic nodules); D-F: CT images revealed an almost normal lung field after treatment.

Figure 6 Abdominal computed tomography images of the patient at different stages of treatment. A: Multiple nodules of spleen were shown on computed tomography (CT) image before chemotherapy (orange arrows, metastatic nodules); B: CT images revealed an almost normal spleen after treatment; C: Large cystic occupying lesion of left renal was shown on CT image before chemotherapy (orange arrows, metastatic cystic occupying lesion); D: CT images revealed an almost normal but smaller left kidney after treatment; E: Large solid occupying lesion of cervix was shown on CT image before chemotherapy (orange arrows, metastatic solid occupying lesion); F: CT images revealed an almost normal cervix after treatment.
