Abstract: Background and Clinical Significance: The paper investigates the use of the Histolog® Scanner, a confocal microscopy–based device, as a potential tool for intraoperative neuropathological diagnosis of brain tumors. Traditional intraoperative diagnosis, relying on frozen sections and squash preparations, can introduce artifacts and consume valuable tissue. The Histolog® Scanner offers a plug-and-play solution capable of acquiring high-resolution images of fresh tissue surfaces in minutes while preserving tissue for further histological or molecular analyses. Cases Presentation: Three clinical cases—two women and one-man, mean age 57.3 years—undergoing neurosurgery for distinct brain lesions were included. Tissue samples were immersed in fluorescent dye, rinsed, and immediately analyzed with the Histolog® Scanner before standard intraoperative histopathology. In the first case, a glioblastoma wild-type, traditional methods struggled to define tumor margins, whereas the device provided rapid, detailed imaging to guide resection. In the second case, a meningioma, the scanner confirmed lesion identity quickly, eliminating the need for a cryostat and reducing artifacts. In the third case, a brain metastasis, integration with cytological apposition allowed simultaneous assessment of lesion margins and nature without freezing the tissue. Conclusions: The Histolog® Scanner demonstrated multiple advantages: rapid intraoperative use, clear margin visualization, preservation of tissue for subsequent analyses, reduce unnecessary resection, thereby helping to lower the risk of recurrence. This device may complement standard intraoperative methods, enhancing diagnostic accuracy and influencing postoperative treatment planning. Overall, the Histolog® Scanner represents an innovative tool combining speed, precision, and tissue preservation, suggesting a promising role in establishing a new standard for intraoperative neurosurgical diagnosis.
