Abstract PURPOSE Stereotactic radiosurgery (SRS) has become the mainstay to treat BM. Follow-up MRI provides important information on lesion treatment response and guides future therapy planning. Volumetric measurements of BM have shown promise over traditional uni- two-dimensional in more accurate repeatable assessment. However, routine clinical use yet be achieved because workflow is laboriou...

introduction:neurogenic mediastinal tumors comprise a wide range of benign and malignant diseases. a group of these tumors, located at thoracic apex, sometimes spread to cervical spaces causing numerous surgical difficulties. in thoracotomy approaches, due to proximity of the tumors to major blood vessels, complete removal of these tumors from cervical spaces is impossible or may cause intraope...

introduction: different imaging modalities are used to evaluate salivary gland diseases, including tumors. ultrasonography (us) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. the aim of this study was to evaluate the role of us in differentiating malignant from benign parotid tumors, in the context of previous controversy...

Inflammatory myofibroblastic tumors (IMFTs) are rare neoplasms of unclear origin that are most commonly found in the lungs and the abdominopelvic region, with rare involvement of the larynx [1-3]. Some cases of IMFT have shown immunohistochemical expression of anaplastic lymphoma kinase (ALK) [3]. ALK positivity confers a higher likelihood of recurrence but a lower chance of metastasis and ther...
