A 64-year-old man with a midbrain cavernoma and prior bleeding presented with a 1-week history of diplopia, partial left oculomotor nerve palsy, and worsening dysmetria and right-sided weakness. MRI revealed a hemorrhagic left tectal plate and midbrain cavernoma. A left suboccipital supracerebellar transtentorial approach in the sitting position was performed for resection of his lesion utilizing the lateral mesencephalic sulcus safe entry zone. Postoperatively, he developed a partial right oculomotor nerve palsy; imaging depicted complete resection of the cavernoma. He recovered from the right third nerve palsy, weakness, and dysmetria, with significant improvement of his partial left third nerve palsy.The video can be found here: https://youtu.be/ofj8zFWNUGU.

✓ The authors report a new technique for en bloc petrosectomy using a Gigli saw as an alternative to drilling the petrous bone in the combined supra- and infratentorial approach or the transpetrosal—transtentorial approach. It is simple and easy and avoids postoperative cosmetic deformity. This technique has been performed in 11 petroclival lesions without injuring the semicircular canals, the cochlea, or the facial nerve.

Transtentorial Approach

The posterior interhemispheric approach is a versatile approach to access lesions of the pineal region, posterior incisural space, posterior region of third ventricle, and adjacent structures. We demonstrate the case of a 26-year-old woman with symptoms of increased intracranial pressure and hydrocephalus caused by a meningioma at the posteromedial tentorial incisura. Gross-total removal of the tumor was successfully achieved via a posterior interhemispheric transtentorial approach. The patient reported an immediate and significant symptomatic improvement after surgery. The detailed operative technique and surgical nuances, including the surgical corridor, tentorium incision, tumor dissection and removal are illustrated in this video atlas.The video can be found here: https://youtu.be/nSNyjQKl7aE.

Transtentorial Approach

Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy. No specific clinical presentation or tomographic examinations findings was identified before treatment, suggestive of a diagnosis of menigioma. The clinical and laboratory features were very similar to the most common tumors of the pineal region. Prior to the surgery, the histology of these tumors was not suspected. Both patients underwent direct surgery and complete removal was achieved by a suboccipital transtentorial approach. The tumors originated from velum interpositum in both cases. At the follow up, one case presented with recurrence six years later, and she underwent a reoperation with total resection without morbidity. Long-term follow up presented no other recurrences.

The authors present the autopsy findings of two related patients and the biopsy findings of a thrid member of the family. The oldest member was 34 years old at death and on postmortem examination he had haemangioblastomas in the retina, cerebellum, medulla and spinal cord. Other findings were renal cell carcinoma, phaechromocytoma, cysts of kidney and pancreas, hydromyelia and atypical meningiomas. His brother died when 30 years old. The autopsy revealed haemangioblastomas of cerebellum, renal cell carcinoma and a clear cell cystadenoma of epididymus. The third patient was the daughter of the first and presented with headache and dizziness. CT-scan showed a cerebellar haemangioblastoma. Epidemiological considerations on the commonest visceral and CNS lesions and a review of current diagnostic criteria are discussed.
