RESUMO
@#As one of the important contents of eyes, aqueous humor is always in dynamic circulation. When any part of the outflow is blocked, the aqueous humor outflow(AHO)circulation will break down, and followed by the increase of intraocular pressure, the damaged visual function, and the optic nerve injury. At last, the glaucoma occurs. Therefore, it can promote to locate the blocked part by observing the structure of the AHO and evaluating its function state, so as to clarify the pathogenesis of primary open angle glaucoma. Current imaging techniques for AHO pathway include optical coherence tomography(OCT)and angiography of outflow. This article will review the research progress of structure and function imaging of AHO.
RESUMO
Retroperitoneal hemangiopericytoma is a kind of uncommon tumor. We report a case of 41-year-old man who was diagnosed retroperitoneal tumor without significant symptoms by abdominal ultrasonography. Abdominal CT and MRI scans show a 6 cm × 5 cm solid tumor delineated clearly from adjacent organs. Excision of the tumor was performed and the histopathological examination confirmed the diagnosis of hemangiopericytoma.
