Transtentorial Approach

The paramedian supracerebellar transtentorial approach allows unobstructed exposure to the quadrigeminal cistern, tectal plate, pineal region, tentorial incisura, medial basal temporal lobe, and posterior ambient cistern. The authors present a meningioma of the posterolateral tentorial incisura case in a 62-year-old male who presented with a long history of upper-extremity tremors and walking difficulties. MRI revealed supra- and infratentorial tumor extension and hydrocephalus. This approach enabled us to achieve gross-total resection without causing neurovascular injury or any postoperative neurological deficits. For each pathology, the pros and cons of various approaches should be considered based on the anatomy, vasculature, and any surrounding structures.

Ambient Cistern

The middle tentorial incisural space, located lateral to the midbrain and medial to the temporal lobe, contains the ambient cistern through which courses the third, fourth, and fifth cranial nerves, posterior cerebral artery (PCA), superior cerebellar artery, and the choroidal arteries. Arteriovenous malformations (AVMs) in this compartment are supplied by the thalamogeniculate and posterior temporal branches of the PCA, and drain into tributaries of the basal vein of Rosenthal. We present a case of an AVM in this middle tentorial incisural space that persisted after embolization and radiosurgery, and was microsurgically resected through a subtemporal approach. This case demonstrates the anatomy of the middle incisural space and technical aspects in microsurgical resection of these rare AVMs.The video can be found here: https://youtu.be/V-dIWh8ys3E.

Abstract BACKGROUND Approaching ambient cistern lesions is still a challenge because of deep location and related white matter tracts (WMTs) and neural structures. OBJECTIVE To investigate the white matter anatomy in the course of 3 types of transtemporal-transchoroidal fissure approaches (TTcFA) to ambient cistern by using fiber dissection technique with translumination and magnetic resonance imaging fiber tractography. METHODS Eight formalin-fixed cerebral hemispheres were dissected on surgical corridor from the temporal cortex to the ambient cistern by using Klingler's method. The trans-middle temporal gyrus, trans-inferior temporal sulcus (TITS), and trans-inferior temporal gyrus (TITG) approaches were evaluated. WMTs that were identified during dissection were then reconstructed on the Human Connectome Project 1021 individual template for validation. RESULTS The trans-middle gyrus approach interrupted the U fibers, arcuate fasciculus (AF), the ventral segment of inferior frontoocipital fasciculus (IFOF), the temporal extensions of the anterior commissure (AC) posterior crura, the tapetum (Tp) fibers, and the anterior loop of the optic radiation (OR). The TITS approach interrupted U fibers, inferior longitudinal fasciculus (ILF), IFOF, and OR. The TITG approach interrupted the U fibers, ILF, and OR. The middle longitudinal fasciculus, ILF, and uncinate fasciculus (UF) were not interrupted in the trans-middle gyrus approach and the AF, UF, AC, and Tp fibers were not interrupted in the TITS/gyrus approaches. CONCLUSION Surgical planning of the ambient cistern lesions requires detailed knowledge about WMTs. Fiber dissection and tractography techniques improve the orientation during surgery and may help decrease surgical complications.

Objectives The current video presents the nuances of the endoscopic endonasal transoculomotor triangle approach for the resection of a pituitary adenoma with extension into the ambient cistern. Design The video analyzes the presentation, preoperative workup and imaging, surgical steps and technical nuances of the surgery, the clinical outcome, and follow-up imaging. Setting The patient was treated by a skull base team consisting of a neurosurgeon and an ENT surgeon at a teaching academic institution. Participants The case refers to a 62-year-old female who presented with vision loss and headaches, and was found to have a pituitary adenoma with extension into the ambient cistern. Main Outcome Measures The main outcome measures consist of the reversal of the patient symptoms (headaches), the recurrence-free survival based on imaging, as well as the absence of any complications. Results The patient's headaches improved. There was no evidence of recurrence. Conclusions The endoscopic endonasal transoculomotor triangle approach is safe and effective for addressing pituitary tumors which extend into the ambient cistern.The link to the video can be found at: https://youtu.be/EBLwEWhohxY.

Abstract BACKGROUND AND IMPORTANCE: Cavernous malformations (CMs) arising intrinsically to the cisternal segment of the trochlear nerve are extremely rare. This case of a trochlear nerve cavernous angioma is the third to be reported in the neurosurgical literature and the first to be resected by a middle fossa approach. CLINICAL PRESENTATION: The authors present a case of a 31-year-old woman with progressive left-sided headache and left hemisensory symptoms, whose magnetic resonance imaging showed a solid enhancing tumor in the left ambient cistern at the level of the midbrain-pontine junction causing significant brainstem compression. Intraoperatively, a left trochlear nerve cavernous angioma circumferentially enveloping the nerve was visualized. The angioma was microsurgically resected by a middle fossa approach under frameless stereotactic guidance. Gross total resection of the intrinsic trochlear nerve lesion was achieved, although the trochlear nerve could not be preserved intact. CONCLUSION: CMs should be considered in a possible differential diagnosis of cisternal trochlear nerve tumors. Surgical resection remains the standard of care, and is indicated for relief of compressive symptoms and prevention of future bleeds. Postoperative diplopia often persists; however, resolution of diplopia reported in the literature can be attributed to either regeneration after direct surgical repair of the sacrificed nerve or a spontaneous adaptation over time.

Recklinghausen’S Disease

Abstract A patient who presented with a tumor of the left ambient cistern, a left cerebellopontine angle tumor, and a left orbital tumor causing left hearing loss and left exophthalmos without café au lait spots or cutaneous neurofibromas is described. There was no family history of von Recklinghausen's disease. A cerebellopontine angle tumor removed by a suboccipital craniectomy was an acoustic neurinoma. An ambient cistern tumor was approached through a subtemporal route. A tumor arising from the trigeminal nerve was also a neurinoma. An orbital neurofibroma was excised by a frontal craniotomy with removal of the orbital roof. This rare unilateral association of neurinomas and a neurofibroma on the left side was thought to be a forme fruste of von Recklinghausen's disease, and it could be considered a presentation of a mosaic of von Recklinghausen's disease.
