Diode Laser Management of Cheek Cavernous Hemangioma in Dental Office.

J Craniofac Surg 2022 Jun 27. Epub 2022 Jun 27.

First Department, Removable Prosthodontics, Faculty of Dental Medicine, UMF Carol Davila, Bucharest, Romania.

Due to high energy content and specific characteristics of dental laser light, this kind of procedure optimizes the outcome on oral cavernous hemangioma removal, diminishing the risks, and complications. Management of a very rare internal cheek cavernous hemangioma presenting a high risk of injury in a patient with chronic acenocoumarol medication and high blood pressure, can be accomplished using diode 810nm laser, in the dental office with predictable results. Protocol complied diode laser, with specific fiber tip, specific power, and operation mode, for 1 minute/1 cm2 irradiated area. Read More

Management of hepatic haemangioma in pregnancy.

BMJ Case Rep 2022 Jun 10;15(6). Epub 2022 Jun 10.

Surgical Oncology, University of Rochester Wilmot Cancer Institute, Rochester, New York, USA

Hepatic cavernous haemangioma is a benign tumour of vascular origin found within the liver. Often incidentally diagnosed, the management of these vascular masses is frequently determined by the size of the mass and symptoms associated with its compression of adjacent structures. Tumours >10 cm are known as giant haemangiomas and are associated with increased risks of compression symptoms, coagulopathies and haemorrhage. Read More

Contact-dependent signaling triggers tumor-like proliferation of CCM3 knockout endothelial cells in co-culture with wild-type cells.

Cell Mol Life Sci 2022 Jun 4;79(6):340. Epub 2022 Jun 4.

Department of Human Genetics, University Medicine Greifswald and Interfaculty Institute of Genetics and Functional Genomics, University of Greifswald, Fleischmannstraße 43, 17475, Greifswald, Germany.

Cerebral cavernous malformations (CCM) are low-flow vascular lesions prone to cause severe hemorrhage-associated neurological complications. Pathogenic germline variants in CCM1, CCM2, or CCM3 can be identified in nearly 100% of CCM patients with a positive family history. In line with the concept that tumor-like mechanisms are involved in CCM formation and growth, we here demonstrate an abnormally increased proliferation rate of CCM3-deficient endothelial cells in co-culture with wild-type cells and in mosaic human iPSC-derived vascular organoids.

Acta Neuropathol Commun 2022 May 31;10(1):81. Epub 2022 May 31.

Department of Neuropathology, Institute of Pathology, University Hospital Heidelberg, Heidelberg, Germany.

The International Society for the Study of Vascular Anomalies (ISSVA) has defined four vascular lesions in the central nervous system (CNS): arteriovenous malformations, cavernous angiomas (also known as cerebral cavernous malformations), venous malformations, and telangiectasias. From a retrospective central radiological and histopathological review of 202 CNS vascular lesions, we identified three cases of unclassified vascular lesions. Interestingly, they shared the same radiological and histopathological features evoking the cavernous subtype of angioleiomyomas described in the soft tissue. Read More

Classification of hepatic cavernous hemangioma or hepatocellular carcinoma using a convolutional neural network model.

J Gastrointest Oncol 2022 Apr;13(2):787-791

Department of Interventional Radiology, Tangdu Hospital, Fourth Military Medical University, Xi'an, China.

Background: Computed tomography (CT) is a common imaging technique for diagnosis of liver tumors. However, the intensity similarity on non-contrast CT images is small, making it difficult for radiologists to visually identify hepatic cavernous hemangioma (HCH) and hepatocellular carcinoma (HCC). Recently, convolutional neural networks (CNN) have been widely used in the study of medical image classification because more discriminative image features can be extracted than the human eye.

Revisiting Surgery in the Current Era of Gamma Knife for Cavernous Sinus Lesions.

Neurol India 2022 Mar-Apr;70(2):563-573

Department of Neurosurgery, Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.

Background: The challenges associated with surgeries of cavernous sinus (CS) lesions have shifted the management trend towards upfront gamma knife radiosurgery (GKRS). Although GKRS is effective in arresting the progression of certain small residual/recurrent lesions, its efficacy in alleviating neurological deficits is less evident. Furthermore, GKRS without establishing the histopathological diagnosis, at times can be detrimental. Read More

Multiple spinal intramedullary cavernous angiomas with bleeding episode mimicking an intramedullary tumor.

J Radiol Case Rep 2022 Mar 1;16(3):15-22. Epub 2022 Mar 1.

Anatomical Pathology Department, Faculty of Medicine, Universitas Airlangga, Indonesia.

Intramedullary cavernous angioma is a rare vascular malformation compared to cerebral cavernous malformation. The incidence of cavernous angioma is about 3 - 5% of all central nervous system lesions, 5 - 12% of all spinal vascular lesions, and 1% of all intramedullary lesions in pediatric patients. Although intramedullary cavernous angioma has the same histological picture as cerebral cavernous angioma, the natural history, and surgical approach are different from cerebral cavernous angioma.

Department of Neurosurgery, 401 General Military Hospital of Athens, Kanellopoulou & Mesogeion Avenue, 11527 Athens, Greece.

Skull vault hemangiomas are benign vascular tumours of the calvaria that are usually asymptomatic or present as firm, painless lumps. We present a case of a 59-year-old female with a giant intraosseous calvarial hemangioma that was admitted in our department with a palpable mass over the left frontoparietal region, personality changes and impaired emotional and cognitive functions. The patient was treated with a two-step approach involving endovascular and surgical treatment, and suffered two rare, but recognized complications, a contrecoup intracerebral haemorrhage and valproate-induced stupor and parkinsonism.
