background: colorectal tumor is one of the main causes of death in our country. the aim of the present study was to determine the clinicopathological aspects of tumor and the presence of hepatic micrometastasis in patients with colorectal cancer (crc). materials and methods: forty two patients with crc were evaluated in the study surgical treatment was performed and liver biopsy was taken for t...

Paragangliomas are neoplasms of neural crest origin. In the head and neck, they uncommonly involve the larynx. The distinction between paragangliomas and other neuroendocrine tumors can be difficult. Precise diagnosis is important in order to optimize patient treatment. Diagnosis relies mostly on histopathologic examination followed by immunohistochemistry. Here we report a 77-year-old woman wi...

AbstractGliomas are among the most aggressive and deadly brain tumors. This paper details proposed Deep Neural Network architecture for tumor segmentation from Magnetic Resonance Images. The consists of a cascade three Layer Aggregation neural networks, where each stage elaborates response using feature maps probabilities previous stage, MRI channels as inputs. neuroimaging data part publicly a...

two new cases of aneurysmal bone cyst of the spine are presented. in one of them only the spinous process was involved, and in the second case mthe neural arch and the body were involved. a brief review of the literature with clinical, radiological and pathilogical features of this benign lesion is made and its differential diagnosis, specially from giant cell tumor of the spine emphasised.

Nowadays health is an essential factor in human life, among all the complexities brain tumors are very critical to deal with. Though there some existing techniques classify related deficiencies, no proper method segment process. MRI (Magnetic Resonance Imaging) and ultrasound vastly used order condition over world lately. But exist limitations those processes keenly tumor analysis, this segment...
