In this case report, we describe dysphonia as an uncommon presentation of a rare posterior fossa tumor. To our knowledge, a case of choroid plexus papilloma presenting with dysphonia has not been described before. [ncbi.nlm.nih.gov]

After doing the workup for primary, he underwent sub-occipital craniotomy, and gross total excision. The tumor was greyish, soft, suckable, and very vascular; gross total excision was done. [ruralneuropractice.com]

Clinical presentationThe patient is a 37 year old woman referred from anoutside hospital for workup of an intracranial mass. 3. [de.slideshare.net]

This workup often necessitates a battery of immunohistochemical studies. Transthyretin and/or S100 expression is supportive evidence for a choroid plexus neoplasm, although, unfortunately these stains are not 100% reliable. [r-radiology.com]

Total surgical resection is the treatment of choice for choroid plexus tumors. However, the hypervascular nature of such lesions imposes challenges to the surgical treatment. [ncbi.nlm.nih.gov]

Treatment planning included placement of a ventriculoperitoneal shunt to treat hydrocephalus and to allow the child to grow prior to resection. [inovaideas.org]

This case highlights the available treatment and good prognosis that is possible with Choroid plexus papilloma. [ncbi.nlm.nih.gov]

Immunophenotype cytokeratins: positive (especially CK7) vimentin : positive transthyretin usually positive also found in normal choroid plexus better prognosis if positive 10 S100 variable better prognosis if positive 10 KIR7.1 usually positive and specific [radiopaedia.org]

Complete resection of this malignant tumor is the primary goal of treatment since it allows best chance of survival and improves the overall prognosis [1] [4] [5]. [file.scirp.org]

One theory of the etiology involves the presence of simian vacuolating virus No. 40 (SV40)–related viral DNA. Pathology: They may arise wherever a choroid plexus exists. Tumoral distribution varies between pediatric and adult patients. [thamburaj.com]

Etiology CPPs arise from the single layer of cuboidal epithelial cells lining the papillae of the choroid plexus. [emedicine.medscape.com]

There is no significant sex predilection. [1] Etiology Although the vast majority of choroid plexus tumors are sporadic, hereditary factors appear to play a role in the development of some choroid plexus papillomas and carcinomas. [r-radiology.com]

Epidemiology Frequency CPPs are rare, comprising less than 1% of brain tumors in patients of all ages. [emedicine.medscape.com]

Epidemiology Choroid plexus papilloma accounts for less than 1% of all brain tumors, and about 2-4% of those that occur in children. 10-20% of all choroid plexus papillomas aise in the first year of life. The average incidence is 0.3 per 1,000,000. [prod.wiki.cns.org]

The relatively small number of CPC cases in the literature, coupled with the lack of relevant epidemiological data and controversies about their clinical and pathological diagnosis makes it difficult to establish a standardized therapeutic approach in [journals.plos.org]

The challenges in this situation are to recognize CSF leak, to rapidly understand the pathophysiology of the leak, and to choose the best treatment strategy in emergency. [ncbi.nlm.nih.gov]

Pathophysiology The tumor is neuroectodermal in origin and similar in structure to a normal choroid plexus. They may be created by epithelial cells of the choroid plexus. [howlingpixel.com]

TWIST-1 is involved in the p53 tumor suppressor pathway as an inhibitor. [19] Pathophysiology Symptoms from choroid plexus tumors generally result from secretion of CSF by tumor cells, leading to an increased amount of fluid and, eventually, to hydrocephalus [emedicine.medscape.com]

We recommend precise evaluation of intracranial cystic lesions to prevent wrong diagnosis and operation. Total resection of all enhancing nodules in cystic choroid plexus papilloma is proposed to warrant total cure of tumor. [ncbi.nlm.nih.gov]

In this particular case, two lines of chemotherapy had failed, and poor marrow reserve secondary to craniospinal radiotherapy in an adult patient (36 Gy of craniospinal irradiation and 54 Gy to the cranium) prevented further delivery of cytotoxics. [pagepress.org]

Chemotherapy contributes to long-term survival, but it can not prevent recurrence [ 8 ]. Bleggi-Torres et al. reported 15 cases of CPC and the oldest patient of his series is 22 years old [ 9 ]. [panafrican-med-journal.com]
