Gliomas enhance variably and a complete lack of enhancement can also occur. In the article Bone Tumors - Differential diagnosis we discussed a systematic approach to the differential diagnosis of bone tumors and tumor-like lesions.

This tumor was ignored. This patient has been observed closely for 25 years and despite obvious mass effect he has no visual complaints and the neuro-ophthalmologic evaluation is normal. CT is the most accurate method for evaluating bone destruction of the inner and outer tables the lytic or sclerotic nature of the lesion and for the evaluation of mineralised tumour matrix 123 6MRI is best to depict marrow involvement of the diploe and to evaluate the associated soft tissue. Incidence of pulmonary embolism and impact on mortality in patients with malignant melanoma. The Journal seeks to publish high. Ganesh Diagnostic is a renowned diagnostic centres and pathology labs Rohini in the state of Delhi in India.

Magnetic resonance imaging MRI is usually less efficient than CT in the acute stage of pituitary apoplexy. Magnetic resonance imaging MRI with pituitary protocol is the preferred study to characterize lesions even if computed tomography CT. MRI is useful in showing intracranial extension. It can view organs that may be obscured by bone or foreign bodies on conventional x-rays or CT scans. In this article which is the first in a series of three we will discuss the most common bone tumors and tumor-like lesions in alphabethic order. With special sequence MRI is useful for early detection.

Adenomas can grow from many glandular organs including the adrenal glands pituitary gland thyroid prostate and othersSome adenomas grow from epithelial tissue in nonglandular areas but express glandular tissue structure as can happen in familial polyposis coli. Tumors and metastases of the brain. It is capable of showing the tissues from multiple viewpoints and is. Some of these lesions are easily identified by radiographic appearance. According to their biological behavior lesions of the adrenal grands can be classified into being benign or being malignant including primary or metastatic Table 1Different lesions have different treatment options and clinical prognoses so it is of great clinical value to make a differential diagnosis based on computed tomography CT and. The mass is located along the course of the right hypoglossal nerve.

Multiple logistic regression analysis showed that cystic pituitary adenomas and Rathke cleft. MRI is superior in most cases in which differentiation of soft tissues is necessary. A cystic hygroma also known as a cystic lymphangioma is a benign fluid-filled sac caused by a malformation of the lymphatic system. Quantitative parameters of magnetic resonance imaging cannot predict human epidermal growth factor receptor 2 HER2 status in rectal cancer. An MRI is usually completed to assess for tumors and a bone density test will provide information about bone strength and possible disorders eg osteopenia osteoporosis. Differential diagnosis include adenoma myelolipoma cyst lipoma pheochromocytoma adrenal cancer metastatic cancer hyperplasia and tuberculosis.
