Pneumocephalus and pneumorrhachis are related to transgression of the barriers to the central nervous system. We present a patient with a Pancoast tumor treated with palliative chemoradiation who developed symptomatic spinal and intracranial air caused by spontaneous bronchopleurodurosubarachnoid fistula secondary to direct tumor invasion into the thecal sac.

Macroscopic and microscopic characteristics of 210 spontaneous ovarian tumors from 7748 Sprague-Dawley rats are described. The tumors were classified as tubular adenoma, anaplastic adenocarcinoma, papillary cystadenoma, papillary cystadenocarcinoma, mesothelioma, sertoliform tubular adenoma, Sertoli's cell tumor, granulosa cell tumor, thecal cell tumor, polycystic sex cord/stromal tumor, and li...

BACKGROUND A postoperative magnetic resonance imaging (MRI) is performed as a routine to assess decompression of the spinal cord as well as to evaluate postoperative complications. The purpose of this study is to analyze the efficacy of postoperative MRI for hematoma in spinal decompression surgery. METHODS Between January 1, 2008 and January 31, 2015, 185 patients who underwent postoperative...

We examined a free-living Symbiodinium species by light and electron microscopy and nuclear-encoded partial LSU rDNA sequence data. The strain was isolated from a net plankton sample collected in near-shore waters at Tenerife, the Canary Islands. Comparing the thecal plate tabulation of the free-living Symbiodinium to that of S. microadriaticum Freud., it became clear that a few but significant...

The authors present distinctive computed tomographic (CT) findings in two cases of long-standing ankylosing spondylitis accompanied by the cauda equina syndrome. Multiple, asymmetric erosions of the posterior elements of the lumbar spine on CT were correlated with thecal diverticula demonstrated by myelography. The pathogenesis of these erosions may be related to arachnoiditis in the early phas...

BACKGROUND Recently, several members of the transforming growth factor-beta (TGF-beta) superfamily have been shown to be essential for regulating the growth and differentiation of ovarian follicles and thus fertility. METHODS Ovaries of neonatal and adult sheep were examined for expression of the TGF-betas 1-3 and their receptors (RI and RII) by in situ hybridization using ovine cDNAs. The ef...

Objectives of this study were to determine if concentrations of steroids, insulin-like growth factor-I (IGF-I) and IGF-II in follicular fluid, and numbers of LH and IGF-I receptors change during growth of the dominant follicle. Ovarian follicular development was monitored daily via ultrasound in lactating Holstein cows. Animals were bilaterally ovariectomized when the dominant follicle (DF) was...

Angiogenic factors are associated with angiogenesis during follicular development in the mammalian ovary. The aim of the present study was to determine the relationships between the vascular network and mRNA expressions of angiopoietins (Ang)-1, Ang-2 and hepatocyte growth factor (HGF), and their receptors in follicles at different developmental stages during follicular development. Ovaries in ...

We present the case of a 27-year-old man who had a soft-tissue lumbar spine mass causing back, abdominal, and groin pain. Imaging showed the lesion filling the right neural foramen, invading the anterior L2 vertebral body and both pedicles, and protruding into the central canal, causing compression of the thecal sac. The final pathologic diagnosis was a malignant peripheral nerve sheath tumor, ...
