Choroid plexus tumors (CPTs) are rare intraventricular tumors comprising approximately 1% of all brain tumors. The common locations are the lateral ventricle (most common location in children), the third and fourth ventricles (most common location in adults), and cerebellopontine angle. Here, we present the case of a 10-month-old child with complaints of fever (99.6F), abnormal eye movements, and bilateral papilledema. Ultrasound cranium of the child revealed a well-defined hyperechoic lesion adjacent to the trigone and occipital horn of the right lateral ventricle. No vascularity could be appreciated on color Doppler. Non-contrast computed tomography of the brain showed a well-defined lobulated mass lesion epicentered at the choroid plexus of the right lateral ventricle which was hyperdense relative to the brain parenchyma with specks of calcification. Contrast-enhanced magnetic resonance imaging showed a solid intensely enhancing lobulated mass lesion with frond-like morphology originating from the choroid plexus of the occipital horn of the right lateral ventricle. Surgical excision of the CPT was done under aseptic conditions. We try to reinforce the ultrasound (USG), CT, and MRI findings of a CPT which ultimately came out to be a choroid plexus papilloma (CPP) on histopathological examination.

Plexus Papilloma

Abstract The authors report the successful total removal of a rare intracranial tumor in the right lateral ventricle of a 15-year-old girl with epileptic seizures. Histopathological examination showed a benign tumor formed by mature cartilage and choroid plexus papilloma. From our review of the literature, a mixed tumor with these histological features has not been reported previously in this location. The diagnosis, surgical approach, etiology, and prognosis of this lesion are discussed.

A red, firm 3.5x3.0x3.0cm mass was found within the right lateral ventricle, compressing the hippocampus and thalamus of the brain of a 4-year-old cow. The pituitary was enlarged and firm. Histologically, both the brain and pituitary masses consisted of moderately pleomorphic epithelial cells arranged as rosettes or sheets supported by a delicate fibrovascular stroma. Based on anatomical localization, histopathological and immunohistochemical findings, a diagnosis of choroid plexus carcinoma with pituitary metastasis was made.

Plexus Papilloma

Primary neoplasms of the central nervous system have been rarely reported in sheep. A three-year-old Rasa Aragonesa ewe was admitted to the small ruminant external consultancy at the Veterinary Faculty of University of Zaragoza, Spain. Clinical, haematological and neurological examinations were performed. Neurological examination showed signs of ataxia, hyperextension of the right front limb and abnormal postural reactions. The animal was unable to stand and walk, even with help. Patellar and flexor reflexes were normal and superficial sensation was present but decreased. Humanitarian sacrifice was carried out one month later. Gross and histopathological findings revealed a choroid plexus papilloma located in the fourth ventricle of the brain. To the authors’ knowledge this is the first description of this neoplastic disorder in sheep.

Plexus Papilloma

A 12 year-old boy with headaches for 2 months. Magnetic resonance imaging of the brain found a small lesion in the atrium of the right lateral ventricle. We show a posterior interhemispheric approach to the ventricular atrium through a corticotomy in the pre-cuneus and the posterior cingulate gyrus. This approach has the advantage of avoiding lesion to the optic radiation. A complete resection of the lesion was performed without complications. Anatomopathological result showed choroid plexus papilloma. This benign tumor corresponds to less than 1% of brain tumors and typically presents with signs of intracranial hypertension with hydrocephalus.

On the dissection of the brain of a patient who died with an unclear diagnosis, it was found that from the lower horn of the right lateral ventricle, stretching it and adjoining the ependymus with its shell, a tumor emanates, which, with projection on the surface, occupies the area of the anterior central crown of the gyrus, the entire part of the temporal.

e13039 Background: Choroid plexus papilloma (CCP) is a rare primary neuro-ectodermal tumor of the choroid plexus, representing less than 1% of intracranial tumors in adults. The most common location in adults is the 4th ventricle and treatment is gross total resection (GTR). Leptomeningeal disease (LMD) can rarely occur, even when the tumor retains benign histology. Because of the rarity of DCCP, there is no standard treatment, with less than 20 published cases. There have no previous descriptions of the use of BEV therapy in DCCP. Methods: We present 2 patients (pts) with DCCP, who received gross total resection, radiation and chemotherapy with continued progression, who received treatment with BEV therapy. Results: Pt 1 presented with a 4th ventricular mass and evidence of LMD. GTR of the posterior fossa lesion revealed an atypical CCP. The pt received craniospinal radiation with concurrent temozolomide (TMZ) therapy. After 4 years, there was leptomeningeal disease progression and the pt developed progressive radicular pain and weakness, unresponsive to typical treatments. He was initiated on TMZ and BEV therapy, but the TMZ was discontinued due to thrombocytopenia and the pt was continued on BEV alone. While the MRI showed stable disease at, the pt had complete remission of pain and some improvement of ataxia. When BEV was held due to toxicity, the pain returned until BEV was restarted. Carboplatin was added to BEV with progression of LMD at 21 months. Pt 2 is a 58-year-old man who present with a 4th ventricular mass, shown to be CCP after gross total resection. The pt received radiotherapy for diffuse sacral recurrence. After three years of surveillance, the pt received lomustine and 6-thioguanine for disease progression, limited to 5 cycles by thrombocytopenia. After 5 years, the pt noted continued progressive radicular pain in his lower extremities. The pt completed a planned course of 10 doses of bevacizumab and had improvement in pain control and stable imaging at 11 months. Conclusions: While bevacizumab resulted in stable imaging when used in DCCP, there was significant improvement in debilitating radicular symptoms. The complications of BEV therapy must be considered with the potential benefit of symptomatic relief. Prospective studies are needed.

Plexus Papilloma

A 7-year-old spayed female English Cocker Spaniel was examined because of a 1-week history of lethargy, stumbling over objects and circling, and the presence of two tonic-clonic generalised seizures two days before presentation. The neurological signs suggested a lesion involving the right forebrain. Computed tomography revealed the presence of two intracranial masses, one located inside the right lateral ventricle and the other located in the right frontal lobe attached to the falx cerebri. Because of the poor prognosis, the owner refused to continue with the therapy and the dog was euthanised. On postmortem examination one mass was diagnosed histologically as a meningioma and the other as a papilloma of the choroid plexus. Information in the veterinary literature on multiple malignancies affecting the central nervous system is very limited. To the best of the authors’ knowledge, the association of meningioma and choroid plexus papilloma has never been reported either in the human or in the veterinary medical literature.
