Posterior fossa giant tumefactive perivascular spaces: 8-year follow-up in an adolescent
نویسندگان
چکیده
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 remained asymptomatic during the 8-year follow-up after diagnosis with the serial magnetic resonance imaging (MRI) showing no change in the size and morphology of the lesion. CONCLUSION This case supports prior literature on supratentorial GTPS suggesting that the natural history of GTPS is mostly benign. Identification of GTPS in the posterior fossa could prevent the patient from unnecessary surgery or other aggressive treatment modalities.

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 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...

BACKGROUND Virchow-Robin spaces (VRS) or perivascular spaces are interstitial cystic spaces surrounding the vasculature of brain parenchyma and course from the subarachnoid space. Small VRS (<2 mm) appear in all age groups, but can enlarge and be confused with other lesions like cystic neoplasms. These enlarged VRS are termed giant tumefactive perivascular spaces (GRPVS). CASE DESCRIPTION We ...

A 53-year old man presented with seven months history of progressive weakness of extension of the digits and the thumb of the left hand. The wrist extension was normal and sensations were also intact. The patient had also been noticing a progressively enlarging lump on the lower anterolateral aspect of the left antecubital fossa for the last three months. Physical examination andelectro diagnos...
متن کاملA case of giant cholesteatoma extending to the posterior fossa.
We present a 43-year-old male patient who developed a giant cholesteatoma with lateral sinus obliteration and involvement of the posterior cranial fossa. The only complaints were left-sided aural discharges and total sensorineural hearing loss. Examination revealed a mass lesion consistent with cholesteatoma within the left middle ear. Computed tomography and magnetic resonance imaging showed a...
