Image-guided resection of aggressive sacral tumors

Resection of large sacral tumors: a report of 4 cases

Tumors of the sacrum and related neurological and pelvic structures are rare pathologic conditions. Sacral tumors are a diagnostic challenge because patients often present with nonspecific complaints such as low back pain, sacrococcygeal joint pain, referred lag and buttock pain. Because of diagnostic and radiographic challenges, the detection of sacral mass can be delayed which complicates any...

Image-Guided Brain Tumor Resection

Surgical treatment of primary brain tumors remains a considerable challenge for the neurosurgeon. Nonetheless, surgery is the mainstay of glioma therapy because it provides the means of obtaining absolute tissue diagnosis, mapping tumor margins, mechanical cytoreduction, and guidance of adjuvant therapy such as brachytherapy, gene therapy, or radiosurgery. Recent developments in computation tec...

Image-Guided Transurethral Resection of Bladder Tumors – Current Practice and Future Outlooks

Transurethral resection of bladder tumor (TURBT) under white light cystoscopy (WLC) is the cornerstone for the diagnosis, removal and local staging of non-muscle invasive bladder cancer (NMIBC). Despite technological improvements over the decades, significant shortcomings remain with WLC for tumor detection, thereby impacting the surgical quality and contributing to tumor recurrence and progres...

Image-Guided Percutaneous Ablation of Renal Tumors

Renal tumors account for more than 50,000 new cases annually in the United States with a rising incidence (Chow et al., 1999). This is mainly because of an increase in diagnosis due to widespread use of cross-sectional imaging (Pantuck et al., 2001). Renal cell carcinoma constitutes 4% of all adult malignancies (American Cancer Society, 2008) and about 70 to 80 percent of patients presenting wi...
