 The consistency of pituitary macroadenomas affects the complexity of surgical resection. On T2-weighted (T2W) imaging, the intensity ratio of the tumor to the cerebellar peduncle (tumor to cerebellar peduncle T2-weighted imaging intensity [TCTI] ratio) correlates with meningioma consistency. We aimed to determine the correlation of this radiographic finding with pituitary macroadenoma consistency and to determine whether it can be used for preoperative planning.

Craniofacial pain syndromes are comprised of multiple pathological entities resulting in pain referred to the scalp, face, or deeper cranial structures. In a small subset of patients affected by those syndromes, pharmacological and physical therapies fail in alleviating pain. In some of those refractory patients surgical procedures aimed at relieving pain are indicated and have been adopted with variable results and safety profiles.

Indocyanine Green and Contrast-Enhanced Ultrasound Videoangiography: A Synergistic Approach for Real-Time Verification of Distal Revascularization and Aneurysm Occlusion in a Complex Distal Middle Cerebral Artery Aneurysm.

World Neurosurg

May 2019

Oncological Neurosurgery Unit, Department of Neurosurgery, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy; Department of Pathophysiology and Transplantation, Università degli Studi di Milano, Milan, Italy.

Background: Distal outflow occlusion and extracranial-intracranial bypass represent a possible option for the surgical management of complex middle cerebral artery (MCA) aneurysm. A limitation of the distal clipping strategy combined to bypass is related to the difficulties in predicting intraoperatively the good blood flow supply to the brain territory distal to the aneurysm and the extent and speed of aneurysmal thrombosis.

Methods: We present an innovative approach in which contrast-enhanced ultrasound (CEUS) and indocyanine green videoangiography (ICG-VA) have been synergistically used to study the effect of distal clipping on the aneurysm flow and the parenchymal blood flow after the bypass.

Piezosurgery for Infra- and Supratentorial Craniotomies in Brain Tumor Surgery.

World Neurosurg

February 2019

Department of Neurosurgery, Fondazione IRCCS Istituto Neurologico Carlo Besta, Milan, Italy.

Objective: Piezoelectric surgery represents an innovative technique to perform safe and effective osteotomies and is an alternative to traditional bony tissue management using rotating or perforating instruments. We evaluated the safety and feasibility of craniotomies using an ultrasonic device that allows the selective cut of mineralized structures, avoiding damages to the vascular, dural, and parenchymal structures.

Methods: We analyzed a series of 300 patients (age range, 1-81 years; SD ± 15.

Oncology and cerebrovascular disease constitute two of the most common diseases afflicting the central nervous system. Standard of treatment of these pathologies is based on multidisciplinary approaches encompassing combination of interventional procedures such as open and endovascular surgeries, drugs (chemotherapies, anti-coagulants, anti-platelet therapies, thrombolytics), and radiation therapies. In this context, therapeutic ultrasound could represent a novel diagnostic/therapeutic in the armamentarium of the surgeon to treat these diseases.

Objective: Cavernous sinus invasion (CSI) in Cushing's disease (CD) negatively affects the probability of complete resection, biochemical cure, and need for adjuvant therapy. However, the prediction of CSI based on MRI findings has been inconsistent and variable. Among macroadenomas, the Knosp classification is the most widely utilized radiographic predictor of CSI, but its accuracy in predicting CSI and the probability of gross-total resection is limited in the setting of microadenomas or Knosp grade 0-2 macroadenomas.

Von Hippel-Lindau (VHL) disease is a multisystem genetic disease, the cardinal manifestations of which include central nervous system hemangioblastomas (CNS HB), renal cell carcinomas (RCC), and pheochromocytoma. Tumorigenesis in VHL of both RCC and CNS HB occurs secondary to downstream effects of a mutated or absent VHL protein. Treatment of RCCs with tyrosine kinase inhibitors (TKIs) such as Pazopanib is now first line therapy, but their effect on VHL-associated CNS HBs remains unknown.
