To evaluate the feasibility and clinical value of magnetic resonance diffusion tensor imaging (DTI) with fluorescein sodium staining (FLS) in the resection of high-grade glioma (HGG) in functional brain areas. ⋯ The application of DTI with FLS can facilitate the maximum resection of HGG in functional brain areas with minimum loss of fiber tracts, reduce the disability rate, and improve quality of postoperative life compared with traditional glioma surgery.

It is rare for breast carcinoma to metastasize to the pituitary gland; this finding indicates extensive metastasis of the primary tumor. ⋯ Pituitary gland metastasis is rare and difficult to differentiate from a pituitary adenoma without a pathologic diagnosis. Surgery is the first choice for treatment. Surgery, radiotherapy, and chemotherapy are combined with endocrine therapy to tailor treatment to the results of immunohistochemistry.

Management of vascular malformations requires microcatheter manipulation through distal tortuous arterial feeders <1 mm in diameter to permit safe and effective embolization at the fistula or nidus location. The ASAHI CHIKAI 008 microguidewire (ACM) recently introduced in the United States was used to evaluate microcatheter torque, support, and safety in distal microcatheter navigation. ⋯ The ACM is a safe, sturdy microguidewire that provides good torque in distal arterial anatomy, while providing microcatheter support and maintaining tip configuration on repeated use.

The endoscopic endonasal approach to the infratemporal fossa (ITF) has gained popularity. However, the inferior turbinate and/or lacrimal duct are often removed when performing endoscopic medial maxillectomy for ITF approach, and there is potential risk for empty nose syndrome or epiphora. Although the endoscopic prelacrimal recess approach was introduced to avoid these complications, there were some limitations associated with surgical freedom. We report a 2-port endoscopic technique using both prelacrimal recess and antral window as a means to preserve the inferior turbinate and lacrimal duct, while facilitating instrument availability during ITF tumor resection. ⋯ We propose a hybrid endoscopic surgical procedure for ITF tumors using both endoscopic prelacrimal recess approach and transantral window. This technique provides surgeons an adequate working space via a bimanual technique through 2 different ports, while preserving normal sinonasal structures.
