Hyperamylasemia following the trans-sphenoidal resection of pituitary tumor: can propofol-remifentanil TIVA cause postoperative hyperamylasemia?: A case report

The trans-sphenoidal resection of a recurred pituitary tumor was performed in a 42 years old man under general anesthesia with propofol and remifentanil. Neither massive bleeding nor hypotension was observed intraoperatively, but bradycardia was sustained over five hours. The patient did not suffer from hypertriglyceridemia and there was no evidence of drug toxicity or vigorous intervention during the surgery, however hyperamylasemia was observed one day after the surgery. It is presumed that vagal stimulation by propofol and remifentanil infusion might induce bradycardia and abnormal pancreatic enzyme secretion consequently.

A Case of Desmoplastic Infantile Ganglioglioma / 영남의대학술지

The desmoplastic infantile ganglioglioma is very rare cerebral tumor. It has been known to be characterized by its voluminious size, intense desmoplasia and the frequent presence of astrocytic and ganglioglionic differentiation. Also, It is usually presented in infantile period and predilected in the frontal and parietal lobes. We treated a huge desmoplastic infantile ganglioglioma(8?7?6cm) on the right frontotemporo-parietal area with only gross total resection. It includes solid mass & several cysts and shows the areas of the proliferation of spindle cells exhibiting storiform pattern in dense desmoplastic stroma and the areas composed of spindle shaped glial component.

Secretory Meningioma: Report of 2 cases

The secretary meningioma is a distinct variant of meningioma that revealed characteristic light microscopic, immunohistochemical and ultrastructural features of epithelial and secretary differentiation, which was named as a distinct subtype of meningioma by Alguacil-Garcia et al in 1986. We experienced 2 cases of secretary meningioma. One was a 53-year-old female who had suffered from sudden onset of dizziness for I day. The computerized tomography revealed a sharply marginated well enhanced mass in temporal lobe. The other was a 59-year-old female who had suffered from dizziness for 8 years. The computerized tomography revealed a well demarcated lobulated mass in petrosal ridge. In both cases, multiple hyaline inclusions were scattered in the background of meningothelial meningioma. They were PAS positive, diastase resistant, stained yellow with van Gieson, and did not stain with reticulin in contrast to Psammoma bodies. The immunohistochemistry revealed positive reaction for EMA, CEA, a-FP and cytokeratin. T'he electron microscopic study revealed interdigitation with desmosomes and abundant intracellular lumina. They were lined by numerous microvilli and filled with granular material which was composed of electron dense homogenous material, me branous material, and small membrane-bound vesicles. Microvilli were filled with electron dense material identical to the material in the lumina, and some of them were interconnected with electron dense material in the lumina. It was concluded that secretary activity of the meningothelial cells and degenerated microvilli were involved in the pathogenesis of hyaline inclusions.
