“…Cysts develop within the tumor or adjacent cortex in 7.5% of patients with CPPs. They are found on imaging either before birth, after birth, or following surgical resection [2,19,31,41,52,76]. Cysts range in size and occur on or directly beneath the ependymal lining.…”

“…CSF cytological examination for malignant cells should be an integral part of the patient's initial evaluation [36]. The lateral ventricles are the most common primary sites (Table 1) [4,11,12,19,31,66]; less common locations are the third and fourth ventricles [8,10,18,81,82]. Metastases occur predominately along the cerebrospinal fluid axis; however, extra CNS metastatic disease has been reported in the abdomen, lung, and bone [81].…”

“…Choroid plexus tumors (CPTs) are papillary neoplasms of neuroectodermal origin arising from the choroid plexus epithelium of the cerebral ventricles [6, 9, 14, 22, 27, 32, 33, 35, 36, 42, 44, 47, 54, 56-58, 65, 66, 68, 81]. CPTs are uncommon comprising only 10% of all brain tumors in infants and 5% of all perinatal brain tumors [20,31,35,64]. Due to their rarity and because they mimic more common intracranial conditions, such as hemorrhage, infection, and hydrocephalus secondary to congenital defects, these tumors may be missed [36,79].…”

Introduction The object of this review is to describe the choroid plexus tumors (CPTs) occurring in the fetus and neonate with regard to clinical presentation, location, pathology, treatment, and outcome. Materials and methods Case histories and clinical outcomes were reviewed from 93 cases of fetal and neonatal tumors obtained from the literature and our own institutional experience from 1980 to 2016. Results Choroid plexus papilloma (CPP) is the most common tumor followed by choroid plexus carcinoma (CPC) and atypical choroid plexus papilloma (ACPP). Hydrocephalus and macrocephaly are the presenting features for all three tumors. The lateral ventricles are the main site of tumor origin followed by the third and fourth ventricles, respectively. CPTs of the fetus are detected most often near the end of the third trimester of pregnancy by fetal ultrasound. The extent of surgical resection plays an important role in the treatment and outcome. In spite of excellent survival, which is especially true in the case of CPP, surgical resection may carry significant risks in an immature baby. Given the neonatal low blood volume and increased vascularity of the tumors, there is potential risk for hemorrhage. Although advances in neurosurgical techniques have led to a greater degree of complete surgical resections, survival for the perinatal CPC group remains low even with multimodality therapies. Conclusion Perinatal CPTs have variable overall survivals depending on degree of surgical resection and tumor biology. An increased understanding of the molecular features of these tumors may lead to improved therapies and ultimately survival. Keywords Fetal choroid plexus papilloma.

“…13,19,22,24 The most common cyst content was fluid, which typically appears as homogeneous low intensity on the T1-weighted images and homogeneous high intensity on the T2-weighted images. 2,13,17,18,22,[25][26][27] The majority of cases occur in young patients, usually in the third or fourth decade. They usually present with cranial nerve impairment on the affected side, but the presenting symptoms may be highly variable and include headache, cerebellar symptoms, hemifacial spasm and meningitis!…”
