Conventional histopathology with hematoxylin & eosin (H&E) has been the gold standard for histopathological diagnosis of a wide range of diseases. However, it is not performed in vivo and requires thin tissue sections obtained after tissue biopsy, which carries risk, particularly in the central nervous system. Here we describe the development of an...
A 45-year-old male presented with subacute onset of a right-sided hemiparesis, right homonymous hemianopsia, and slurred speech. The brain imaging revealed two separate intraparenchymal enhancing lesions. The cerebrospinal fluid rapid plasma reagin and venereal disease research laboratory test were positive and consistent with syphilitic gumma, and...
Dextran-coated superparamagnetic iron oxide nanoparticles (dextran-SPIO conjugates) offer the attractive possibility of enhancing MRI imaging sensitivity so that small or diffuse lesions can be detected. However, systemically injected SPIOs are rapidly removed by macrophages. We engineered embryonic cells (HEK293T) to express major macrophage scave...
With advances in genomic profiling and sequencing technology, we are beginning to understand the landscape of the genetic events that accumulated during the neoplastic process. The insights gleamed from these genomic profiling studies with regards to glioblastoma etiology has been particularly satisfying because it cemented the clinical pertinence ...
Cerebral radiation necrosis is a serious late complication after conventional radiotherapy that can present with focal neurologic deficits or with more generalized signs and symptoms of increased intracranial pressure, depending on the location. The incidence and severity of radionecrosis are dose-volume dependent. We report a case of cerebral radi...
Leptomeningeal metastasis is a devastating complication of the central nervous system in patients with late-stage solid or hematological cancers. Leptomeningeal metastasis results from the multifocal seeding of the leptomeninges by malignant cancer cells. Although central nervous system metastasis usually presents in patients with widely disseminat...
A 45-year-old man with a new diagnosis of low grade glioma was started on an escalating dose of levetiracetam (Lev) for seizure management. He gradually developed intractable nausea/vomiting and a high creatinine concentration due to acute renal failure which was attributed to Lev-induced interstitial nephritis. The medication was changed and his r...
