Abstrakt: Meningiomas that arise in the atria of the lateral ventricles are relatively rare lesions, that pose a unique challenge for surgery due to their deep-seated location and proximity to critical white matter tracts. Size and anatomical variations can affect the best approach for these tumors, with several approaches described to access the atrium including the interhemispheric trans-precuneus, trans-supramarginal gyrus, distal trans-sylvian, supracerebellar trans-collateral sulcus, and finally the trans-intraparietal sulcus approach, which was the choice for this case. Minimally invasive techniques that preserve the surrounding tissue are becoming increasingly popular and are perfectly suited to deep seated lesions. The relevant subcortical anatomy surrounding the atrium is discussed. The optic radiations form the lateral wall of the atrium, whereas commissural fibers of the tapetum form the roof of the atrium, and superficial to these fibers we have the superior longitudinal fasciculus that have vertical rami that communicate with the superior parietal lobule. Utilizing the posterior half of the intraparietal sulcus can preserve these fibers. The use of neuronavigation, brain magnetic resonance imaging with diffusion tensor imaging (DTI) tractography may be helpful in the surgical planning. In this article, we present a surgical video of a trans-tubular interparietal sulcus approach for resection of an atrium meningioma. A 43-year-old right-handed female who presented with progressive headaches and a diagnosis of idiopathic intracranial hypertension was found to have an atrial meningioma that grew in follow-up and surgery was recommended. We chose the posterior intraparietal sulcus approach as it provides a good angle of attack while preserving the optic radiations and most of the superior longitudinal fasciculus, using a tubular retractor to minimize tissue damage. Gross total resection of the tumor was achieved with complete preservation of patient neurological function.
