Dynamic visualization of arachnoid adhesions in a patient with idiopathic syringomyelia using high-resolution cine magnetic resonance imaging at 3T.

A 39-year-old female patient with thoracic syringomyelia underwent routine magnetic resonance imaging (MRI) and 3 T MRI to investigate the value of retrospectively cardiac-gated cine steady-state free precession (SSFP) MRI in the preoperative and postoperative diagnosis of arachnoid membranes in the spinal subarachnoid space. Therefore, 3T MRI included sagittal and transverse retrospectively cardiac-gated cine balanced fast-field echo (balanced-FFE) sequences both preoperatively and after microsurgical lysis of arachnoid adhesions and expansive duraplasty. Arachnoid membranes were detected and this result was correlated with intraoperative findings and the results of routine cardiac-gated phase-contrast cerebrospinal fluid (CSF) flow MRI.

Progressive multifocal leukoencephalopathy developing in advanced pulmonal sarcoidosis.

Coincidence of pulmonal sarcoidosis and progressive multifocal leukoencephalopathy (PML) rarely occurs. So far an entire course has been recorded in only very few cases. We demonstrate the case of a 49-year-old male developing an infratentorial localized PML in the setting of advanced pulmonal sarcoidosis.
