A Steerable Microcatheter Effectively Worked in Tumor Embolization.
J Neuroendovasc Ther
October 2024
Department of Neurosurgery, Mie University Graduate School of Medicine, Tsu, Mie, Japan.
Objective: A Leonis Mova (LM; SB Kawasumi, Kanagawa, Japan), one of the steerable microcatheters, has a remote-controlled flexible catheter tip manipulated with a dial in the hand grip, which enables operators to overcome complicated branching in endovascular surgeries. We report a case of a pituitary tumor in which the LM worked effectively as a distal access catheter (DAC) in tumor embolization.
Case Presentation: A female patient in her 70s complained of bitemporal hemianopsia, and an MRI revealed a pituitary tumor that appeared hypervascular.

Following a unilateral post-chiasmal lesion of the geniculo-striate pathway, patients develop homonymous visual field defects. Using classical perimetry, patients with 'complete' homonymous hemianopia are unaware of stimuli in the affected hemifield. However, some show preserved vision in the affected hemifield in which the conscious perception of moving stimuli is preserved (Riddoch phenomenon).

A collision tumor is a rare neoplastic lesion consisting of two or more coexisting, distinct cell line entities. In this report, we present the case of a 56-year-old male patient with a history of colon cancer who presented to the emergency room with visual deficits that had started about eight months earlier. An ophthalmologic examination reported left homonymous hemianopsia, prompting a brain MRI, which showed a right posterior temporal extra-axial mass concerning intracerebral metastatic colon cancer, in consideration of patient history.

Beaumont Hospital, Beaumont Health, Royal Oak, MI, United States.
Papillary craniopharyngiomas are rare tumors prevalent to the precision oncology world due to their high rate of BRAF V600E mutations. Symptoms include vision loss, neuroendocrine dysfunction, and cognitive dysfunction. Treatment involves an interdisciplinary approach with surgery, radiation, and systemic treatment.
