Fig. 8From: Detection of genes mutations in cerebrospinal fluid circulating tumor DNA from neoplastic meningitis patients using next generation sequencingA representative case. (a) The head contrast enhanced MRI. This showed the linear and strip abnormal enhancement of the cerebellar sulcus (red arrow) after the patient had a headache during the icotinib therapy for the primary tumor. (b) The May-Gruwald-Giemsa staining of the CSF sample. The data showed the tumor cells in the CSF (× 1000). (c) The head contrast enhanced MRI. This showed the dramatic improvement and complete response. (d) The May-Gruwald-Giemsa staining. The data showed fewer tumor cells (× 1000), when compared to that in BBack to article page
