Case Reports
Advanced neuroimaging studies in a patient with brain metastases from transitional cell carcinoma of the bladder.
The differential diagnosis in single or oligo-brain lesions in metastatic cancer patients remains broad. Advanced imaging studies can be employed to help refine the differential and potentially guide treatment. ⋯ Resection of both lesions revealed metastatic transitional cell carcinoma. This is the first report of octreotide scan characteristics in a patient with transitional cell carcinoma with central nervous system (CNS) metastases. The octreotide avidity of these transitional cell CNS metastases suggests the presence of somatostatin receptors that may be considered as a potential therapeutic target.

Case Reports
Presumptive progressive multifocal leukoencephalopathy in multiple sclerosis after natalizumab therapy.
To describe a patient with relapsing remitting MS who was treated with natalizumab for 36 months. First symptoms of presumptive progressive multifocal leukoencephalopathy (PML) appeared 14 weeks after her last natalizumab infusion. ⋯ This case represents a presumptive PML after discontinuation of natalizumab treatment-similar to the definition established for PML in HIV patients.
