We present a case of intraventricular meningioma resected via a transcortical approach using tractography for optic radiation and arcuate fasciculus preservation. We include a review of the literature. A 54-year-old woman with a history of breast cancer presented with gait imbalance. Workup revealed a mass in the atrium of the left lateral ventricle consistent with a meningioma. Whole brain automated diffusion tensor imaging (DTI) was used to plan a transcortical resection while sparing the optic radiations and arcuate fasciculus...

Patients with breast cancer are surviving longer as the state of the art for care advances. Because patients are surviving longer with primary breast cancer, the incidence of secondary metastatic disease has risen. Metastatic breast cancer to the brain was once thought to be universally fatal. While it is still quite lethal, its treatment after diagnosis is increasingly safe and effective. Critical progress has been made in understanding the interaction between breast metastases and the neural niche, neuroimaging of functional anatomy, minimally invasive image-guided brain surgery, characterizing subtypes of breast cancer based on molecular and genetic profiles, and individualized pharmaceuticals and immunotherapies...

The purpose of this study was to develop a straightforward method of supplementing patient anatomy and estimating out-of-field absorbed dose for a cohort of pediatric radiotherapy patients with limited recorded anatomy. A cohort of nine children, aged 2 to 14 years, who received three-dimensional conformal radiotherapy for low grade localized brain tumors (LBTs), were randomly selected for this study. The extents of these patients' computed tomography simulation image sets were cranial only. To approximate their missing anatomy, we supplemented the LBT patients' image sets with computed tomography images of patients in a previous study with larger extents of matched sex, height, and mass and for whom contours of organs at risk for radiogenic cancer had already been delineated...

Oligometastases means the state which the anatomy and physiology may limit or concentrate metastases to a single or a limited number of organs. In patients with oligometastatic breast cancer their prognosis may be good, although the impact of local therapy has not been evaluated prospectively. The development of minimally invasive surgical techniques and highly conformal ablative radiotherapy allow for safe and effective ablation of metastatic lesions in most locations. A biopsy(preferably providing histology)of a metastatic lesion has been recommended to confirm diagnosis particularly when metastasis is diagnosed for the first time...

Amy S Colwell, Joani M Christensen
Breast reconstruction following mastectomy has evolved to preserve the native skin and nipple of the breast and create a natural-appearing reconstruction in 1 or 2 surgeries. Nipple-sparing procedures appear to be oncologically safe with low risks of cancer recurrence. In our series of 2,182 nipple-sparing mastectomies, there was no development or recurrence of cancer in the nipple. Direct-to-implant single-stage surgery offers the patient a complete reconstruction at the time of mastectomy. Patient selection centers on preoperative breast anatomy combined with postoperative goals for size and uplift of the breast...

For left-sided postmastectomy patients requiring chest wall plus comprehensive nodal irradiation, sometimes traditional techniques such as partial wide tangents or electron/tangents combination are not feasible due to abnormal chest wall contour or heart position or unusually wide excision scar. We developed electron chest wall irradiation technique using Electron Monte Carlo (EMC) dose algorithm that will achieve heart sparing with acceptable ipsilateral lung dose, minimal contralateral lung, and breast dose...

Ventriculoperitoneal (VP) shunt placement is among the most common surgical procedures undertaken by neurosurgeons. Complications arising from the thoracic portion of the shunt are relatively rare in comparison with those of the intraventricular and peritoneal portions. Disruption of primary breast development following VP shunt placement has not previously been reported. The authors describe the case of a 15-year-old girl referred to the plastic surgery department with a significant right breast deformity and associated asymmetry following VP shunt placement performed during the neonatal period...

BACKGROUND: Radiofrequency (RF) ablation for denervation has been utilized for decades in chronic pain management. This relies on the proper targeting of the affected nerve which may be obtained by creating an ablation lesion with a shape and volume that optimizes targeting. Various systems designed to improve lesion size are available. These include cooling the active tip (cooled-RF) and protruding the RF electrode outside the active tip (PERF). OBJECTIVES: This study compares lesion volumes of 3 commercially available RF systems: cooled-RF, "V" shaped active cannula and protruding electrode (18 g and 20 g), and monopolar RF (MRF; 16 g, 18 g, and 20 g)...

During High Dose Rate Brachytherapy (HDR-BT) the spatial position of the radiation source inside catheters implanted into a female breast is determined via electromagnetic tracking (EMT). Dwell positions and dwell times of the radiation source are established, relative to the patient's anatomy, from an initial X-ray-CT-image. During the irradiation treatment, catheter displacements can occur due to patient movements. The current study develops an automatic analysis tool of EMT data sets recorded with a solenoid sensor to assure concordance of the source movement with the treatment plan...

The whole-body positron emission tomography (PET)/magnetic resonance (MR) scan is a cutting edge technology providing comprehensive structural information from MR imaging and functional features from PET in a single session. Recent research findings and clinical experience have shown that (18)F-fluorodeoxyglucose (FDG) whole-body PET/MR imaging has a diagnostic performance comparable with or superior to that of PET/CT in the field of oncology, including for breast cancer. In particular, FDG PET/MR mammography in the prone position with the breast hanging in a pendant manner can provide more comprehensive information about the metabolism, anatomy, and functional features of a breast lesion than a whole-body PET/MR scan...

Reduction mammaplasty is the volumetric reduction in the bulk of the breast. Techniques have evolved from primarily reducing the breast bulk to reducing with emphasis on functional and aesthetic outcome. The deeper understanding of the surgical anatomy of the breast has guided this development. While Paulus Aegina (sixth century AD), Dieffenbach (1848) and Gaillard-Thomas (1882) set the pace in glandular reduction; Pousson (1897) and Dehner (1908) focused on breast ptosis. It took quite some time before the enigma of the vascularization to the nipple areolar complex could be solved...
