RESUMO

Although intraparenchymal meningiomas have rarely been reported in the literature, the papillary type has been reported only as infratentorial. Here we report the case of a 21-year-old female patient with intraparenchymal lesion. To our knowledge, this case describes the first report of a patient with a supratentorial intraparenchymal papillary meningioma.

RESUMO

The authors present a rare case of cavernous angioma mimicking a meningioma in a 58-year-old man who presented with a headache and dizziness. There were no neurological deficits or other neurological symptoms or signs. An extra-axial mass lesion thought to be associated with diffusely well-enhanced falx in the postcontrast sections was noted in the posterior interhemispheric fissure near the posterior part of the corpus callosum splenium. Extra-axial cavernous angiomas (cavernomas) are extremely rare lesions. They most commonly occur in the parenchyma but have been occasionally reported to arise from the dura matter. Dural cavernous angiomas arise from dural sinuses, falx cerebri, tentorium cerebelli, cranial base dura, or internal auditory canal dura and convexity. Parenchymal cavernous angiomas classically have a ring of hemosiderin surrounding the lesions observed on magnetic resonance imaging, but dural cavernous angiomas do not display the same magnetic resonance imaging characteristics and occasionally exhibit a dural tail sign due to which they can often be misdiagnosed as meningiomas.

RESUMO

BACKGROUND: Renal cell carcinoma is an interesting tumor due to its unpredictable behavior. Common metastatic sites of renal cell carcinoma are the lungs, lymph nodes, bones and liver. Concurrent thyroid metastasis of clear cell carcinoma is uncommon but it can appear as a rapidly growing cervical, painless nodular mass. CASE REPORT: We report a case of a 56-year-old male patient with clear cell renal carcinoma confirmed on a histopathological examination. The patient noticed a rapidly growing mass in the thyroid region when receiving medical anticancer therapy. Because of that, gray-scale thyroid ultrasonography and a fine-needle aspiration biopsy were performed. The histopathological examinationof the biopsy specimen revealed a lesion composed of malignant epithelial cells compatible with metastasis of renal carcinoma. CONCLUSIONS: In patients with with a history of RCC, both past and present, a thyroid mass, especially co-existing with an adenomatous goiter, should prompt a work-up for thyroid metastasis.

RESUMO

BACKGROUND: Vertebroplasty and kyphoplasty are minimally invasive techniques used to treat vertebral compression fractures. The etiology of vertebral compression fractures varies among patients. Although osteoporosis and trauma are major etiologic factors in patients with a vertebral compression fracture, unexpected results were found in 11 patients in the present study. The aim of the present retrospective study was to determine the incidentally detected pathology results of patients with vertebral fracture treated by vertebroplasty and kyphoplasty. METHODS: From February 2010 to November 2015, 616 patients with a vertebral compression fracture were treated by kyphoplasty and vertebroplasty at our institution. Vertebral biopsies were obtained from 533 patients during a vertebral augmentation technique. The average patient age was 62.4 years. Of the 616 patients, 388 were female and 228 were male. Histological evaluation of the biopsy specimens from the vertebral compression fractures was performed. RESULTS: The biopsy results of 505 patients showed various stages of bone healing. Among these patients, malignancy was identified in 23 patients, and 43 patients had a history of malignancy. In 6 patients, an unsuspected malignancy was found, and 1 patient had Paget's disease. Infection was detected in 4 patients. In our study, the rate of unsuspected malignancy was 1.1%. CONCLUSIONS: Tissue examination is useful and could reveal pathologic fractures. An incidentally detected biopsy result could change the treatment of patients; however, bone biopsy should be reserved for those patients whose preoperative radiological diagnosis raises suspicion of a nonosteoporotic etiology.
