非典型脉络丛乳头状瘤一例

非典型脉络丛乳头状瘤（atypical choroids plexus papilloma,ACPP）是2007年WHO对中枢神经系统肿瘤分类的一个新的扩展类型,归于脉络丛肿瘤类,即介于脉络丛乳头状瘤和脉络丛乳头状癌的中间类型。随着研究的深人发现三者在生物学特性上有很大的差异。现结合文献复习报道我院一例手术病理证实为ACPP的病例。

MRI findings of choroid plexus tumors in the cerebellum

Choroid plexus tumors (CPTs) are uncommon primary intracranial tumors. Here, we describe two patients with CPTs of the cerebellum: one had a choroid plexus papilloma located in the left cerebellar hemisphere that presented as an irregular, lobulated and solid-cystic mass, whereas the other had a choroid plexus carcinoma that exhibited a poorly defined, mixed-intensity mass associated with invasion of adjacent brain parenchyma. Contrast-enhanced MR imaging showed prominent heterogeneous enhancement. CPTs should be considered in the differential diagnosis for irregular, heterogeneous and intensely enhancing masses that occur in the cerebellum.     

Unusual small choroid plexus cyst obstructing the foramen of monroe: case report

This is a case report of unusual case of choroid plexus cyst at the right foramen of Monro in the anterior third ventricle that caused unilateral obstructive hydrocephalus. The value of small-FOV thin-section MR imaging in the diagnosis of small lesions of the foramen of Monroe is demonstrated. The immunohistochemical findings in choroid epithelial cysts in comparison with those of other types of cysts at this location are discussed.     

Choroid plexus carcinoma of the foramen Luschka: a case report

Choroid plexus carcinoma(CPC) is a rare intracranial neoplasm that usually arises in the supra-tentorial region of infants. We report an adult case of CPC that arose in the foramen Luschka. A 61-year-old woman presented with a 10-year history of dysarthria. CT showed an iso- to slightly high density mass in the left foramen Luschka. The tumor appeared as a low- to iso-intensity area in T1-weighted MR images, and as an iso- to high-intensity area in T2-weighted images. The tumor showed homogeneous enhancement with the administration of contrast medium. Imaging findings were non-specific and the differential diagnosis was difficult.     

Intraductal papillary carcinoma of bilateral breasts: a case report

We report a 59-year-old woman presenting with a 2-month history of occasional bloody discharge from her right nipple and a palpable right breast mass on self-examination. The mammography revealed heterogeneously dense fibroglandular stromas of bilateral breasts, a lobulated mass in her right breast associated with faint pleomorphic microcalcifications, and, in addition, very faint focal granular microcalcifications in the left breast. Breast ultrasound revealed a lobulated and heterogeneous hypoechoic tumor with irregular margins at the right breast and a well-circumscribed tumor with heterogeneous echotexture at the left breast.     

Fetal choroid plexus cysts: a report of 100 cases

A prospective study was undertaken to evaluate the prevalence and significance of fetal choroid plexus cysts detected on screening ultrasound (US) scans. One hundred cases of fetal choroid plexus cysts were detected from 11,700 examinations: There were 95 healthy newborns, three newborns with trisomy 18, one newborn with syndactyly of the toes, and one intrauterine death. In the three neonates with trisomy 18 the cysts were large (greater than 1 cm in diameter), and additional abnormalities were detected. Although there is a clear association between fetal choroid plexus cysts and trisomy 18, amniocentesis or chorionic villus sampling should be reserved for high-risk patients with either large cysts or US evidence of other abnormalities.     

A case report of atypical choroid plexus papilloma in the cervicothoracic spinal cord

Choroid plexus papillomas (CPPs) are uncommon, benign intracranial tumors that can occur in both children and adults. In adults, CPPs are typically identified in the fourth ventricle, whereas in children, they most commonly occur in the lateral ventricle. CPPs that arise from the extraventricular system are extremely rare and difficult to diagnose. We report a case of extraventricular, atypical CPP located in the cervicothoracic spinal cord of a 2-year-old girl.
