Abstract

to 1020-W/cm2 range. With some refinements and with superior energy storage materials, even higher peak power in the petawatt range should be possible from tabletop systems. In this paper we show the ultimate achievable power and intensity, as well as their applications in science and technology. Their applications cover a wide variety of fields, such as precision surgery, micromachining, coherent and incoherent X-ray generation, thermonuclear ignition, particle acceleration, and nonlinear quantum electrodynamics.

Highlights

ConclusionsSPECT/CT provides accurate anatomic correlation and localization of metastatic foci and can serve as a baseline study to assess interval response to treatment
Malignant struma ovarii is an ovarian teratoma containing at least 50% thyroid tissue which has the potential to metastasize and produce thyroid hormone
Thyroidectomy followed by a diagnostic staging radioiodine scan and a stimulated thyroglobulin level should be considered in patients with malignant struma ovarii for guiding therapeutic iodide-131 scan (I-131) administration as metastatic risk is difficult to predict based on histopathologic examination

Summary

Conclusions

This unusual case presents important considerations in the care of patients with malignant struma ovarii. Staging with a diagnostic whole body radioiodine scan and stimulated Tg level following thyroidectomy needs to be considered in all patients with intermediate and high-risk histopathology findings. The I-131 scan should include SPECT/CT imaging, which can demonstrate additional areas of metastases missed on planar imaging, allows for accurate anatomic correlation of metastatic lesions, and can impact treatment decisions [16]. When I-131 treatment is given, a post-therapy I-131 scan should always be obtained two-seven days after treatment to assess for additional findings as compared with the diagnostic I-131 scan [17]. The role of sex hormones and hCG in thyroid cancer arising from both struma ovarii and the thyroid gland should be explored further
