“…CPP is a benign tumor with slow-growing rate and low malignant evolution 7,8 . The supratentorial location is the most common site of the CPP origin, mainly in children [9][10][11][12][13][14] . When all age groups are considered together, the most frequent location is the lateral ventricle (43%-67%), followed by the fourth ventricle (24%-39%) and third ventricle (9.5%-11%) 16,17 .…”

The cerebellopontine angle is an extremely unusual location, accounting for only 9% of all CPTs and these are almost exclusively found in adult patients [9][10][11][12][13][14] .

Introduction: Choroid plexus tumors (CPTs) are rare papillary neoplasms derived from choroid plexus epithelium. They account for only approximately 0.4%-0.6% of all intracranial tumors, but 10%-20% of brain tumors occurring throughout the first year of life. Objective: The present study describes the case of an adult man presenting a cerebellopontine angle choroid plexus papilloma (CPP) microsurgically treated through suboccipital far-lateral approach. Case report: A 67-years-old-man was admitted presenting progressive headaches and left lower limb weakness. Magnetic resonance images showed a large tumor on the left cerebellopontine angle with heterogeneous contrast enhancement. Total surgical resection was achieved through a right suboccipital far-lateral craniotomy on lateral position with neurophysiological monitoring of lower cranial nerves. No alterations on cranial nerves function was observed during tumor resection. The patient presented an uneventful recovery and was discharged home on the fifth post-operative day. On the six months follow-up, he was asymptomatic. Anatomopathological analysis confirmed the diagnosis of CPP, WHO grade I. Conclusion: Cerebellopontine angle's cpp is an extremely rare neoplasm that challenges a neurosurgeon ability to deal with tumor in close relation to lower cranial nerves. Appropriate neurosurgical route, surgeons experience and adequate anatomical knowledge of important neural and vascular structures are fundamental to safely remove CPP of the posterior fossa. Suboccipital far-lateral craniotomy gives enough view with minimal retraction to manage the tumor.

Choroid plexus tumors (CPTs) are rare choroid plexus epithelium originated neoplasms. Among all, choroid plexus papilloma (CPP) is the most common type of CPT. Clinical features and signs at diagnosis of CPP in CPA are so extensive and also nonspecific. This work aimed to review the sign and symptoms of CPP tumors in CPA through all cases reported in the literature. In this study, Data regarding presenting symptoms of 60 adult patients (including 53 adult patients identified from the literature and our seven new patients that presented in this study) with CPP in CPA were reviewed. Symptoms related to 8th cranial nerve, lower motor, 7th, and 5th cranial nerves were the most prevalent symptoms respectively following ICP rising and cerebellar signs. The most common symptoms were related to the ICP elevation, cerebellar and auditory system involvement. The rarity of CPP tumors in CPA along with a variety of presenting symptoms makes the diagnosis of CPPs more challenging while considering this variance could be helpful in prompt diagnosis.

“…[ 2 ] CPPs predominantly arise in supratentorial locations in children, while the most common sites in adults were the fourth ventricle and the CPA. [ 3 , 4 ] On the basis of a series of literature reviews, more common clinical presentations of CPA-CPPs include headache and eighth cranial nerve deficits and unsteady gait. [ 5 , 6 ] The symptoms and signs are usually latent and only slowly progressive.…”

Rationale:Choroid plexus papillomas are rare benign central nervous system neoplasms arising from choroid plexus epithelium. They are most often located in the lateral ventricle, followed by the fourth and third ventricles and, rarely, in the cerebellopontine angle.Patient concerns:We report an uncommon case of a 17-year-old boy who presented with neck pain that had lasted for more than 1 month, with accompanying pain and numbness in his upper extremities. His conditions included slight dizziness, nausea, diplopia, paresthesia, and an unsteady gait. Magnetic resonance imaging (MRI) showed huge cerebellopontine angle tumor that extended to the front medulla oblongata.Diagnosis:Choroid plexus papilloma (WHO I) was diagnosed in this patient.Interventions:The patient was referred for neurosurgical intervention. The very large neoplasm was subtotally resected.Outcomes:The symptoms of the patient were gradually alleviated after surgery and subsequent radiotherapy treatment, but unfortunately, follow-up of 2 years later revealed that the disease was recurrent and the young man passed away.Lessons:Neck pain is related to many factors. The case provided an awareness of the origin of severe intracranial disease. It is mandatory to take a thorough clinical assessment with a holistic approach.
