2 Fig. 1 Renal cell carcinoma solitary metastasis. (A) FLAIR sequence demonstrates a hypointense lesion with significant surrounding edema. (B) Cystic mass with associated nodule. Neurosurgery Clinics  , 15-25DOI: ( /j.nec ) Copyright © 2011 Elsevier Inc. Terms and Conditions

3 Fig. 2 Poorly differentiated adenocarcinoma lung metastases. (A) FLAIR sequence demonstrates multiple hyperintense lesions primarily involving the gray-white junction. (B) Postcontrast, these lesions demonstrate prominent enhancement. Neurosurgery Clinics  , 15-25DOI: ( /j.nec ) Copyright © 2011 Elsevier Inc. Terms and Conditions

4 Fig. 3 78 year old male with history of bladder cancer and thyroid cancer. (A) Axial T2 and (B) postcontrast T1-weighted sequence demonstrate several left temporal enhancing lesions. (C) Precontrast T1 sequence lesions demonstrate T1 shortening. (D) Lesions demonstrate low gradient recalled echo (GRE) signal compatible with hemorrhagic metastases.

5 Fig. 4 Melanoma metastases. (A) T1 shortening. (B) GRE sequence demonstrates several additional lesions not seen on T1 sequence. Neurosurgery Clinics  , 15-25DOI: ( /j.nec ) Copyright © 2011 Elsevier Inc. Terms and Conditions

6 Fig. 5 Metastatic primitive neuroectodermal tumor in a 20-year-old man. (A, B) Isointense T2 signal in a solidly enhancing mass. (C) High DWI signal. (D) Corresponding low ADC map consistent with restricted diffusion. Neurosurgery Clinics  , 15-25DOI: ( /j.nec ) Copyright © 2011 Elsevier Inc. Terms and Conditions
