Evaluation of RAPNO criteria in medulloblastoma and other leptomeningeal seeding tumors using MRI and clinical data.

Neuro Oncol 2020 Mar 26. Epub 2020 Mar 26.

Department of Neurology, Second Xiangya Hospital of Central South University, Changsha, Hunan, China.

Early onset cerebral amyloid angiopathy following childhood exposure to cadaveric dura.

Ann Neurol 2019 02 17;85(2):284-290. Epub 2019 Jan 17.

Stroke Research Centre, Department of Brain Repair and Rehabilitation, University College London Queen Square Institute of Neurology and National Hospital for Neurology and Neurosurgery, London.

Amyloid-β transmission has been described in patients both with and without iatrogenic Creutzfeldt-Jakob disease; however, there is little information regarding the clinical impact of this acquired amyloid-β pathology during life. Here, for the first time, we describe in detail the clinical and neuroimaging findings in 3 patients with early onset symptomatic amyloid-β cerebral amyloid angiopathy following childhood exposure to cadaveric dura (by neurosurgical grafting in 2 patients and tumor embolization in a third). Our observations provide further in vivo evidence that cerebral amyloid angiopathy might be caused by transmission of amyloid-β seeds (prions) present in cadaveric dura and have diagnostic relevance for younger patients presenting with suspected cerebral amyloid angiopathy.

Retinal detachment with subsequent silicone oil retinopexy is not uncommon. A known complication of silicone retinopexy is intraventricular migration of the intraocular silicone oil. While the oil itself does not result in direct pathology, misdiagnosis may lead to an unnecessary diagnostic workup and possibly predispose the patient to surgery intervention. Read More

Plasticity of the human visual brain after an early cortical lesion.

Neuropsychologia 2019 05 31;128:166-177. Epub 2017 Oct 31.

Department of Translational Research on New Technologies in Medicine and Surgery, University of Pisa, Pisa, Italy; Department of Developmental Neuroscience, Stella Maris Scientific Institute, Pisa, Italy. Electronic address:

In adults, partial damage to V1 or optic radiations abolishes perception in the corresponding part of the visual field, causing a scotoma. However, it is widely accepted that the developing cortex has superior capacities to reorganize following an early lesion to endorse adaptive plasticity. Here we report a single patient case (G.

Navigation-Linked Heads-Up Display in Intracranial Surgery: Early Experience.

Oper Neurosurg (Hagerstown) 2018 08;15(2):184-193

Department of Neurosurgery, Icahn School of Medicine at Mount Sinai, New York, New York.

Background: The use of intraoperative navigation during microscope cases can be limited when attention needs to be divided between the operative field and the navigation screens. Heads-up display (HUD), also referred to as augmented reality, permits visualization of navigation information during surgery workflow.

Objective: To detail our initial experience with HUD. Read More

Treating Cerebrospinal Fluid Rhinorrhea without Dura Repair: A Case Report of Posterior Fossa Choroid Plexus Papilloma and Review of the Literature.

World Neurosurg 2017 Dec 1;108:990.e1-990.e9. Epub 2017 Sep 1.

Neurosurgery Department, CHRU de Tours, Tours, France; Brain and Imaging, Université François-Rabelais de Tours, UMR Inserm U930, Tours, France.

Background: Choroid plexus papilloma revealed by nontraumatic cerebrospinal fluid (CSF) rhinorrhea has only been described 5 times, to our knowledge, in the literature. 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. We report an original case of posterior fossa choroid plexus papilloma revealed by CSF leak. Read More

Spinal drop metastasis from a benign fourth ventricular choroid plexus papilloma in a pediatric patient: case report.

J Neurosurg Pediatr 2017 Nov 25;20(5):471-479. Epub 2017 Aug 25.

UCSF Benioff Children's Hospital Oakland, California.

Choroid plexus papillomas (CPPs) are typically benign tumors that can occur in any age group but are more commonly found in pediatric patients. Although these tumors are benign, there are several reports in adult patients of distant metastases present either at the time of diagnosis or occurring months to years after initial resection. Here, the authors report the case of a 14-year-old boy who presented with symptoms of elevated intracranial pressure due to obstructive hydrocephalus that was caused by a large fourth ventricular mass.

Atypical choroid plexus papilloma: spontaneous resolution of diffuse leptomeningeal contrast enhancement after primary tumor removal in 2 pediatric cases.

J Neurosurg Pediatr 2017 Sep 7;20(3):284-288. Epub 2017 Jul 7.

Neuro-Oncology Unit.

Atypical choroid plexus papillomas can metastasize in the form of leptomeningeal seeding. Postoperative chemotherapy is the recommended first-line treatment when gross-total removal is not achieved or in cases of disseminated disease. Here the authors report on 2 children with atypical choroid plexus papillomas and MRI findings of diffuse leptomeningeal enhancement at diagnosis, later presenting with spontaneous resolution of the leptomeningeal involvement after removal of the primary lesions.

A Primary Pigmented Choroid Plexus Papilloma Located Within the Sella Turcica: Case Report and Literature Review.

World Neurosurg 2017 Sep 3;105:1039.e13-1039.e18. Epub 2017 Jul 3.

Department of Neurosurgery, Xiangya Hospital, Central South University, Changsha, Hunan, China. Electronic address:

Background: Choroid plexus papillomas (CPPs) are rare benign tumors, and the pigmented subtype is observed even more rarely.

Case Description: We present the case of a 43-year-old woman with complaints of headache and progressive left monocular visual deterioration, whose initial plain computed tomography CT scan showed an ovate high-density tumor located within the insellar region. Magnetic resonance imaging revealed a homogeneously contrast-enhancing tumor extending from the sella turcica to the suprasellar cistern. Read More

Typical Symptoms of Normal-Pressure Hydrocephalus Caused by Choroid Plexus Papilloma in the Cerebellopontine Angle.

World Neurosurg 2017 Feb 29;98:875.e13-875.e17. Epub 2016 Nov 29.

Neuroscience Center, Fukuoka Sanno Hospital, Fukuoka, Japan.

Background: Choroid plexus papillomas (CPPs) are rare benign intracranial tumors. We report a rare case of CPP manifesting with typical symptoms of normal-pressure hydrocephalus rather than obstructive hydrocephalus.

Case Description: A 45-year-old woman presented with a 6-year history of headache and typical symptoms of normal-pressure hydrocephalus, including gait disturbance, urinary incontinence, and cognitive dysfunction, in addition to the more common symptoms of CPP, such as lower cranial nerve dysfunctions and ataxia.

Metachronous Type I pleuropulmonary blastoma and atypical choroid plexus papilloma in a young child.

Pediatr Blood Cancer 2016 12 21;63(12):2240-2242. Epub 2016 Jul 21.

Department of Oncology, Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.

Pleuropulmonary blastoma (PPB) is a rare childhood tumor, often associated with germline DICER1 mutations and a risk for development of other benign and malignant tumors, a constellation termed DICER1 syndrome. A 1-year-old male was diagnosed with Type I PPB and screened regularly thereafter for detection of intrathoracic and intraabdominal disease. Ten months after diagnosis of PPB, he presented with headaches and vomiting. Read More
