Giant tumefactive perivascular spaces.
BACKGROUND AND PURPOSE The brain perivascular spaces (PVSs) are pial-lined, interstitial fluid-filled structures that accompany penetrating arteries. When enlarged, they may cause mass effect and can be mistaken for more ominous pathologic processes. The purpose of this study was to delineate the broad clinical and imaging spectrum of this unusual condition. METHODS Thirty-seven cases of gian...
متن کاملTumefactive perivascular spaces mimicking cerebral edema in a patient with diabetic hyperglycemic hyperosmolar syndrome: a case report
INTRODUCTION Acute cerebral edema is a significant cause of death in patients treated for diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome. CASE PRESENTATION We present the case of a 44-year-old African American woman admitted with acute severe headache and diagnosed with diabetic hyperglycemic hyperosmolar syndrome. Computed tomography of the head showed diffuse leukoencephalopa...
متن کاملMulticystic Perivascular Spaces Mimicking Cystic Neoplasm of Brain
Background: Virchow-Robin (VR) spaces are the fluid-filled perivascular spaces adjacent the brain vessels. The signal intensities of the VR spaces are very similar to those of cerebrospinal fluid (CSF). VR spaces should be distinguished various pathologic conditions, including lacunar infarctions, cystic periventricular leukomalacia, cryptococcosis, cystic neoplasms and neuroepithelial cysts. C...
متن کاملGiant tumefactive perivascular spaces that expanded and became symptomatic 14 years after initial surgery
BACKGROUND Perivascular spaces (PVSs) or Virchow-Robin spaces in the brain are pial-lined interstitial fluid (ISF)-filled structures surrounding the penetrating arteries and arterioles. These spaces appear as 1- to 2-mm in diameter, round, oval, or curvilinear smooth-walled structures on magnetic resonance imaging (MRI). Typical PVSs are asymptomatic. Occasionally, they become enlarged and caus...
متن کاملPosterior fossa giant tumefactive perivascular spaces: 8-year follow-up in an adolescent
BACKGROUND Cystic masses in the posterior fossa are ominous appearing lesions with broad differential diagnosis. Giant tumefactive perivascular spaces (GTPS) are rarely occurring pathological findings in the posterior fossa with unclear etiology and ill-defined long-term prognosis. CASE DESCRIPTION We present a case of a 15-year-old male diagnosed with posterior fossa GTPS. The patient remain...
