Radiologic Features with Pathologic Correlation of an Unusual Large Intraosseous Skull Cavernous Hemangioma.

Am J Case Rep 2019 Apr 16;20:525-530. Epub 2019 Apr 16.

Department of Diagnostic Radiology, University of Puerto Rico, Medical Sciences Campus, San Juan, Puerto Rico.

BACKGROUND Intraosseous cavernous skull hemangiomas are rare benign vascular tumors that are usually found incidentally on imaging, with an asymptomatic and slow-growing course. We present a case in which the patient had a mass on her forehead for many years, which began to grow rapidly after head trauma. Imaging characteristics play a crucial role in the diagnosis and description of this disease, and in differentiating it from other more common calvarial lesions that may present with a similar clinical picture.

Effect of perioperative aspirin use on hemorrhagic complications in elective craniotomy for brain tumors: results of a single-center, retrospective cohort study.

J Neurosurg 2019 04 5:1-10. Epub 2019 Apr 5.

Objective: In daily practice, neurosurgeons face increasing numbers of patients using aspirin (acetylsalicylic acid, ASA). While many of these patients discontinue ASA 7–10 days prior to elective intracranial surgery, there are limited data to support whether or not perioperative ASA use heightens the risk of hemorrhagic complications. In this study the authors retrospectively evaluated the safety of perioperative ASA use in patients undergoing craniotomy for brain tumors in the largest elective cranial surgery cohort reported to date.

Proposal for Modification of Cahan's Criteria Utilizing Molecular Genetic Analyses for Cases without Baseline Histopathology: A Unique Method Applicable to Primary Radiosurgery.

J Neurol Surg B Skull Base 2019 Feb 31;80(1):10-17. Epub 2018 May 31.

Department of Otolaryngology-Head and Neck Surgery, Mayo Clinic, Rochester, Minnesota, United States.

 Cahan's criteria have been utilized since 1948 to establish causality between prior radiation treatment and the development of secondary malignancy. One major criterion specifies that histological and radiographic evidence collected before and after radiation treatment must confirm separate tumor types; however, pretreatment biopsy is rarely obtained prior to radiosurgery for vestibular schwannoma and many other skull base and cranial lesions. Therefore, in these cases Cahan's criteria cannot be validly applied. Read More

Proton therapy for treatment of intracranial benign tumors in adults: A systematic review.

Cancer Treat Rev 2019 Jan 1;72:56-64. Epub 2018 Dec 1.

Radiation Oncology Department, Centre François Baclesse, Caen, France; Archade, Advanced Resource Center for Hadrontherapy in Europe, Caen, France; Normandy University, Université de Caen Basse Normandie, Caen, France; Laboratoire de Physique Corpusculaire, Caen, France.

Introduction: The depth-dose distribution of a proton beam, materialized by the Bragg peak makes it an attractive radiation modality as it reduces exposure of healthy tissues to radiations, compared with photon therapy Prominent indications, based on a long-standing experience are: intraocular melanomas, low-grade skull-base and spinal canal malignancies. However, many others potential indications are under investigations such as the benign morbid conditions that are compatible with an extended life-expectancy: low grade meningiomas, paragangliomas, pituitary adenomas, neurinomas craniopharyngioma or recurrent pleomorphic adenomas.

Materials: Given the radiation-induced risk of secondary cancer and the potential neurocognitive and functional alteration with photonic radiotherapy, we systematically analyzed the existing clinical literature about the use of proton therapy as an irradiation modality for cervical or intracranial benign tumors.

Gamma Knife Management of Skull Base Chordomas: Is it a Choice?

Asian J Neurosurg 2018 Oct-Dec;13(4):1037-1041

Department of Neurosurgery, Mansoura University Hospital, Mansoura, International Medical Center, Cairo, Egypt.

Background: Skull base chordomas are locally invasive tumors which able to extend in different directions with skull base invasion. Although they are histologically benign, they have invasive nature makes total resection virtually impossible to achieve in most cases and this lead to residual tumors after surgery. To decrease postoperative surgical resection morbidity of these tumors, gamma knife radiosurgery (GKRS) was performed as alternative management for these residual chordomas to evaluate its safety and efficacy.
