Patterns of Cerebrospinal Fluid Biomarkers and Amyloid Positron Emission Tomography in a Patient with Cerebral Amyloid Angiopathy-Related Inflammation

Cerebral amyloid angiopathy-related inflammation (CAA-RI) is a distinct subset of cerebral amyloid angiopathy characterized by the auto-inflammatory response to amyloid-laden small arteries of cerebral cortex and leptomeninges. Clinical features include cognitive-behavioral change, headache, focal neurologic deficits and seizure. Because anti-inflammatory treatments can rapidly relieve neurologic symptoms, early diagnosis is critical. Herein, we report a CAA-RI case with distinct laboratory findings of a decreased cerebrospinal fluid amyloid beta 1-42 level and relatively reduced florbetaben uptake in the focal inflammatory lesion during the acute phase of CAA-RI.

Cyclophosphamide-Associated Reversible Cerebral Vasoconstriction Syndrome Presenting as Concurrent Cerebral Infarction and Subarachnoid Hemorrhage

Reversible cerebral vasoconstriction syndrome (RCVS) has several trigger factors, including physical exertion, pregnancy, and the intake of vasoconstrictive agents. These triggers activate the sympathetic nervous system and induce vasoconstriction, thereby leading to an ischemic or hemorrhagic stroke. In this study, we describe case of RCVS in a 73-year-old woman who complained of sudden bilateral leg weakness after taking cyclophosphamide for anti-neutrophil cytoplasmic antibody associated vasculitis. She was diagnosed with concurrent cerebral hemorrhage and cerebral infarction with multiple intracranial vasoconstrictions on imaging analyses.

Hemorrhagic Brain Metastasis in Angiosarcoma

Angiosarcomas are rare, but aggressive malignancies. Reports of brain metastasis are uncommon. In this report, we describe the clinical features of a 62 year-old man who presented with hemoptysis and right-sided weakness. Chest computed tomography showed multiple ill-defined part solid nodules in both lungs and brain magnetic resonance imaging showed multiple hemorrhagic bran masses. The patient underwent whole body proton emission tomography to identify biopsy site and showed multiple bone lesions. A right acetabulum biopsy in confirmed the diagnosis of angiosarcoma.
