Left insula occupying lesion is an ambiguous diagnosis of intracerebral lesions on imaging, which basically belongs to intracerebral tumors.
The left insula is a part of the brain tissue located between the deep surface of the lateral fissure and the frontotemporal parietal, and the presence of an abnormal lesion in the corresponding area, with compression and destruction of the adjacent tissues, suggests that the left insula occupying lesion is firstly considered as a tumor in terms of the final diagnosis. The nature of the lesion is further determined by a combination of enhanced scanning, clinical history, and examination.
The left insula occupying lesion basically needs to be treated by surgery or gamma knife, mainly to try to release the impact of the lesion on the surrounding brain tissues and to reduce the clinical symptoms, and needs to be standardized under the guidance of the clinician.
