“…The first case of this tumor was published by Lowenthal in 1950 [2] that reported a case of Cerebellar hemangioblastoma, with meningeal hemangioblastoma, osseous metaplasia, hypertrophy of the choroid plexus and amorphous calcium overload, in the same subject. Other one was published by Dulai MS, et al [2] an intramedular papillary ependymoma with choroid plexus differentiation and cerebrospinal fluid dissemination to the brain. Cai CE et al [7] , published a case a cystic mass with a mural enhancing nodule centered within the cerebellar vermis with exuberant piloid gliosis secondary to infiltration of the CPP component into the adjacent brain parenchyma.…”

“…This result, in conjunction with the absence of immunoreactivity for epithelial, mesenchymal, and endothelial markers, likely suggests neuroectodermal differentiation of stromal cells [1][2][3] . An another component, known as a cellular variant, where epithelioid tumor cells were arranged in nests encircled by capillaries and/or in pseudo rosette-like structures, was noted.…”

“…CPT account for 0.3%-0.6% of all brain tumors and they represent 2%-4% of those that occur in children under 15 years and 10%-20% in the first year of the life [1] . The 80% of those tumours located in lateral ventricle present in children, fourth ventricle tumors are evenly distributed in all age groups [2,3] .…”

AbstractsChoroid plexus tumors are rare tumors, although choroid plexus tumours account for 0.3%-0.6% of all brain tumors. We presented a rare case in four ventricle tumor, a primitive choroid plexus Papilloma with divergent differentiation potentials. In 43-year-old male, he started with postural vertigo, occipital cephalea, temporary diplopia and right lateropulsion from two years ago. MRI showed hyperintense tumor in the fourth ventricle with signs of cerebral edema and hemangioblastoma was proposed. Microscopically the tumor was composed of two histological components; one consists of blood vessels of different sizes and capillaries type a rich anastomosing network with these stromal cells are epithelioid-looking, broad with eosinophilic cytoplasm, and occasionally were vacuolated or foamy cytoplasm. The second one composed of epithelial cells forming papillae structures of varying sizes and shape with endothelial hyperplasia and some papillae presenting reached glomeruli-like structures, with ependymoma and haemangioblastoma appearance. The case presented may constitute a new neoplastic entity within the recently described spectrum of central nervous system tumors with ependymal features. Just two cases of this rare combination of different histological patterns have been reported in choroid with displacement and maldifferentiation of primitive, multipotent neuroepithelial cells.

Rapid growing cystic variant of choroid plexus papilloma in a fetal cerebral hemisphereWe report the case of a congenital cystic choroid plexus papilloma (CPP) located in the fetal left cerebral hemisphere, in which there was a marked increase in the size of the cyst 1 week before delivery. A 26-yearold Japanese woman was referred to our hospital at 33 weeks of gestation for evaluation of a fetal brain lesion. Ultrasound examination showed a 3.0 × 4.5-cm cystic tumor involving the posterior horn of the left lateral ventricle (Figure 1). The lesion consisted of a hypoechogenic cyst, 3.0 cm in diameter (Figure 1a), within which was a hyperechogenic solid element 1.5 cm in diameter (Figure 1b). The lesion demonstrated low signal intensity on T1-weighted and high signal intensity on T2-weighted magnetic resonance (MR) images, the same as that of cerebrospinal fluid (Figure 2a-d).

Computed tomography (CT) and magnetic resonance (MR) imaging reliably demonstrate typical features of vestibular schwannomas or meningiomas in the vast majority of mass lesions responsible for cerebellopontine angle (CPA) syndrome. However, a large variety of unusual lesions can also be encountered in the CPA. Covering the entire spectrum of lesions potentially found in the CPA, these articles explain the pertinent neuroimaging features that radiologists need to know to make clinically relevant diagnoses in these cases, including data from diffusion- and perfusion-weighted imaging or MR spectroscopy, when available. A diagnostic algorithm based on the lesion's site of origin, shape and margins, density, signal intensity and contrast material uptake is also proposed. Non-enhancing extra-axial CPA masses are cystic (epidermoid cyst, arachnoid cyst, neurenteric cyst) or contain fat (dermoid cyst, lipoma). Tumours can also extend into the CPA by extension from the skull base (paraganglioma, chondromatous tumours, chordoma, cholesterol granuloma, endolymphatic sac tumour). Finally, brain stem or ventricular tumours can present with a significant exophytic component in the CPA that may be difficult to differentiate from an extra-axial lesion (lymphoma, hemangioblastoma, choroid plexus papilloma, ependymoma, glioma, medulloblastoma, dysembryoplastic neuroepithelial tumour).
