background: the aim of this study was to evaluate the reduction in excision cavity volume (ecv) during the whole breast radiotherapy (wbrt). the delineating of reduced cavity volume on secondary ct (computed tomography) might decrease the field size of boost plan. materials and methods: twenty patients were treated having breast conservative surgery. at first, primary ct simulation (ct-1) was d...

Background: Methotrexate (MTX) is one of the frequently used chemotherapeutic agents, especially in hematological malignancies and solid tumors. Objectives: MTX hepatotoxicity symptoms range from elevations in serum aminotransferases to hepatocyte necrosis and fibrosis. The time of medication administration significantly impacts treatment outcomes. Hence this study evaluated the protective eff...

  Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GIST has been shown to over-express c-KIT (CD117), the receptor tyrosine kinase. Imatinib (STI571 or Glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to trea...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...

INTRODUCTION Spontaneous pneumocephalus without any pathological condition is very rare. We described a patient with spontaneous pneumocephalus probably arising from the relatively enlarged air-filling sphenoid sinus. CASE PRESENTATION A 51-year-old woman admitted Imam Reza Hospital, Mashhad, Iran with a sudden onset of severe headache and nausea without any neurological deficit. Brain comput...

Skin melanoma is potentially the most dangerous form among all tumor skin lesions. According to statistics, accounts for about 90% of deaths. The cause high mortality patients early metastasis. At same time, metastases can be localized in almost organs and tissues. In addition local regional metastasis skin, subcutaneous tissue lymph nodes, metastatic distant not uncommon, this dramatically wor...

A patient who was treated for 11 years with cytotoxic drugs for Hodgkin's disease developed cerebral toxoplasmosis. Discrete lesions including an occipital abscess were visualized in the brain by computerized tomography (CT). This permitted a brain biopsy to be taken but the appearances were non-specific. At post-mortem pseudocysts of Toxoplasma gondii were found in several sites within the CNS...

Brain parenchyma schwannoma is a rare intracranial tumor, and especially rare in cerebellar hemisphere. In this report, a case of cerebellar schwannoma in a 52-year-old woman, was studied by computed tomography (CT), magnetic resonance image (MRI) and PET-CT. This tumor was totally removed by surgery. The histological diagnosis of schwannoma was confirmed by histological, HE and immunohistologi...

OBJECTIVE To describe the radiographic, ultrasonographic, computed tomography (CT), magnetic resonance imaging (MRI), and arthroscopic findings in eight dogs with elbow lameness caused by primary flexor enthesopathy. STUDY DESIGN Clinical study. ANIMALS Eight client-owned dogs. METHODS In all dogs, lameness was localized to the elbow by clinical examination. Radiographic examination, ultr...

A 55-year-old woman visited our hospital for an investigation of central bronchiectasis, mucoid impaction and infiltrative shadows on chest CT. She had a 10-year history of bronchial asthma; however, her adherence to treatment was poor. Based on the presence of peripheral blood eosinophilia and immediate cutaneous reactivity to Aspergillus fumigatus, the patient was clinically diagnosed with al...
