Benign metastasizing leiomyoma (BML) is a rare condition due to a histologically benign smooth muscle tumour originating from a uterine leiomyoma. It rarely affects the spine to cause spinal cord compression. Here we report a patient with serial metastases to the thoracic spine causing neurological compromise. The rapid spread of BML in this patient illustrates an aggressive manifestation of a usually benign indolent tumour.

We present our preliminary experience with intraoperative near-infrared indocyanine green-videoangiography (ICG-VA) and analysis of blood flow dynamics using fluorescence intensity assessment in cerebral aneurysm clipping surgery. Thirty-nine patients with 43 intracranial aneurysms underwent microsurgical clipping. Intraoperative ICG-VA was performed before and after clip application. ⋯ ICG-VA provides high resolution images allowing real-time assessment of the blood flow in the parent artery and arterial branches, including the perforators. The intensity diagram is useful for providing a more objective record of the hemodynamics than the traditional ICG-VA, which relies more on subjective assessment and may allow interobserver variability. We conclude that ICG-VA, combined with the intensity diagram, can reduce the morbidity and complications associated with aneurysm clipping and improve patient outcomes.
