PURPOSE Patients with focal seizures often have magnetic resonance imaging (MRI) abnormalities in the brain region of their presumed seizure focus. Neoplasms, ischemic infarctions, inflammatory processes, and other specific pathologic entities have been diagnosed by biopsies of such MRI abnormalities. Two patients with this presentation had brain lesion biopsies with a leading presumptive diagn...

Brain metastases are the most common cancerous neoplasm in the brain. The treatment of these lesions is challenging and often includes a multimodality management approach with whole-brain radiation therapy, stereotactic radiosurgery, and neurosurgery options. Although advances in biomedical imaging technologies and the treatment of extracranial cancer have led to the overall increase in the sur...

background: after lung and prostate cancers, colorectal cancer (crc) is the third most common cancer in men and the second most common cancer in women after breast cancer worldwide. every year, more than one million people are diagnosed with colorectal cancer worldwide and half of these patients die from this disease, making it the fourth leading cause of death in the world. this systematic rev...

Brain metastases are not only the most common intracranial neoplasm in adults but also very prevalent in patients with lung cancer. Patients have been grouped into different classes based on the presence of prognostic factors such as control of the primary tumor, functional performance status, age, and number of brain metastases. Patients with good prognosis may benefit from more aggressive tre...

BACKGROUND Preoperative ultrasound (US) evaluation of central and lateral neck compartments is recommended for all patients undergoing a thyroidectomy for malignant or suspicious for malignancy cytologic or molecular findings. Our aim was to find out how frequent was recurrence in regional lymph nodes in patients with follicular or Hürthle cell neoplasm and usefulness of preoperative neck US in...

Managing a CNS neoplasm during pregnancy presents complex challenges, and population-based studies are lacking. We designed a retrospective cohort study using the Nationwide Inpatient Sample (NIS) to investigate pregnancy outcomes in women with CNS neoplasms. We constructed a logistic regression model for maternal mortality, preterm labor, intrauterine growth restriction (IUGR), and Caesarean d...

aim : this study evaluated the results and efficacy of serum ca 19-9 in determining the nature of a pancreatic solid mass in patients referred for investigation of possible malignancy. background : a wide variety of tumor markers have been proposed for pancreatic cancer but currently the only one with any practical usefulness for diagnosis, prognosis, and monitoring of treatment is “ca 19-9 ”. ...

desmoplastic fibroma (df) is a rare and locally aggressive intraosseous tumor with unknown etiology. the mandible is the common site of involvement in the maxillofacial region. however, it is believed that df can arise in any bone of the body. a wide age distribution has been reported for df occurrence, extending from birth to the sixth decade of life, with a peak incidence at 10 to 19 years of...

malignant melanoma has the heart metastasis rate of 50 - 71%, which seems to be the highest among other malignancies. when a patient presents with cardiac metastases of melanoma, the disease has already spread through the body and therefore hardly curable. this brief review tried to introduce this important condition and discuss its frequency, presentation, diagnosis, histologic findings and tr...

background: within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced x-ray emission. the pixe has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. materials and methods: th...
