Trigeminal Neuralgia Caused by a Choroid Plexus Papilloma of the Cerebellopontine Angle: Case Report and Review of the Literature

Unique Presentation of Cerebellopontine Angle Choroid Plexus Papillomas: Case Report and Review of the Literature

“…Dysfunction of hearing and facial movement, headache, dizziness, papilledema, ataxia, and hydrocephalus are common presentations of CPA CPPs, although other findings have been reported including hypoglossal neuropathy and trigeminal neuralgia. 7,8,17,18,[21][22][23][24][25] Our patient presented with a group of nonspecific clinical signs and symptoms typical of CPA lesions that included headaches, unilateral hearing loss, tinnitus, hydrocephalus, and right facial weakness. There is no single pattern of clinical manifestations of CPA CPPs such that these lesions mimic other tumors common to the CPA while others may imitate cerebellar or jugular foramen lesions.…”

Densely Calcified Atypical Choroid Plexus Papilloma at the Cerebellopontine Angle in an Adult

“… 1 2 The majority of CPPs occur during the first 2 years of life, with 12.5 to 20% (10 to 12%) reported in infants under 1 year of age. 1 3 There have been some reports of “calcified CPP,” “CPP in an adult,” “CPP in the cerebellopontine angle (CPA),” and “atypical form of CPP.” 4 5 6 7 However, a case combining with these four features—adult, dense calcification, atypical form, and CPA—is considered to be extremely rare; such a case has never been encountered among the 8,540 skull base tumors on which the senior author (T.F.) has operated in the past 20 years.…”
