Choroid plexus papillomas (CPPs) are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages. Papillomas have an indolent course and carry a good long-term outcome if gross total surgical resection is achieved. However malignant evolution may occur, with a 10-30% incidence....

Choroid plexus tumors are very rare accounting for 0.5% of all brain tumors. They most commonly occur in childhood and present with features raised intra-cranial pressure. World Health Organization (WHO) classifies them into 3 broad categories namely papilloma (grade 1), atypical 2) carcinoma 3). These seen the supratentorial compartment lateral ventricle followed by third ventricle, being comm...

Cystic meningioma is an uncommon meningioma variant that is often difficult to distinguish from other intra-axial tumors, including necrotic gliomas. Cystic meningiomas located in the ventricle are particularly rare and may be misdiagnosed with other brain tumors, including ependymoma, choroid plexus papilloma and neurocytoma, due to its location. The present study discusses two cases of latera...

B. S., a fourteen-month old infant, was admitted to hospital under the care of Dr. Smallwood, eleven weeks before death with the complaint of cough since the age of three months. This became worse after measles at the age of six months. The cough was always worse in the morning and had been increasing in severity. The infant had been born at full term and was normal in development. There was no...

The choroid plexus produces cerebrospinal fluid and plays an important role in brain homeostasis both pre and postnatally. In vitro studies have suggested that cells from adult choroid plexus have stem/progenitor cell-like properties. Our initial aim was to investigate whether such a cell population is present in vivo during development of the choroid plexus, focusing mainly on the chick choroi...

Choroid plexus papilloma (CPP) is a rare tumor of the central nervous system, which is usually located in the ventricular system and can metastasize to cisterns along the cerebrospinal fluid circulation. CPP is only rarely located in the intraparenchymal. Here, we describe an unusual case of such a tumor in a 25-yearold man. He initially experienced a sudden, generalized tonic-clonic seizure; f...

A 44-year-old man presented with a chief complaint of severe headaches of 3 weeks duration and left-sided unsteadiness. Cranial CT showed a well-marginated, oval, homogeneously enhancing mass within the left CPA cistern. The lateral ventricles appeared moderately dilated. MR study (Fig. 1) showed a parenchymal isointense mass within the left CPA producing upward displacement of the left middle ...

Introduction Choroid plexus tumors (CPT) are defined as papillary neoplasms originating from the epithelium of the choroid plexus within the ventricles. They are classified into mainly two types: -benign choroid plexus papillomas (CPP) (World Health Organization WHO grade I) and -choroid plexus carcinomas (WHO grade III). [1,3] An intermediate group lies between the two groups and is referred t...
