OBJECTIVES To determine the pre-malignant and malignant potential of endometrial polyps and to assess whether different clinical parameters are associated with malignancy in the polyps. STUDY DESIGN Four hundred and thirty consecutive cases of hysteroscopic diagnosis of endometrial polyp were retrieved. The medical records, preoperative vaginal sonography(More)
Galenic dural arteriovenous fistula (DAVF) represents a unique, hard to treat subgroup of tentorial DAVFs. We present an unusual case of hemorrhagic Galenic DAVF in a 54-year-old woman. The fistula drained directly to the vein of Galen through multiple feeders. Complete occlusion of the fistula was achieved through transarterial embolization. Deep venous(More)
Histiocytic sarcoma is a rare, lymphohematopoietic malignant neoplasm composed of tumor cells showing morphologic and immunophenotypic features of mature tissue histiocytes. Involvement of the central nervous system (CNS) as either a part of a systemic disease or as a primary lesion has rarely been described so far. We present a case of primary CNS(More)
Arachnoid cysts are developmental anomalies that represent 1% of all intracranial space occupying lesions. Treatment of symptomatic cases may include shunting of the cyst or an open fenestration of it, among other less acceptable surgical procedures. Each procedure has its own pros and cons. We present a case of the development of an acute intracranial(More)
Subependymal giant cell tumor (SGCT) is a benign intraventricular tumor, usually located near the foramen of Monro. It is almost always associated with tuberous sclerosis complex (TSC). SGCTs may obstruct cerebrospinal fluid (CSF) pathways. Rarely, they may secrete a protein-rich exudate, causing communicating hydrocephalus. Surgery is indicated for(More)
BACKGROUND Nowadays meningiomas are frequently detected incidentally. Their natural history has not yet been established because it is difficult to predict the growth pattern. Therefore, the management, after the radiological diagnosis, is still controversial. OBJECTIVES To evaluate the clinical outcome and growth rate of conservatively treated(More)
Dear editor, We would like to present a case with long-term follow-up after surgical resection of a large intracranial hemangiopericytoma in a 1-month-old infant. The child was admitted to our hospital because of decreased levels of consciousness and recurrent vomiting. A brain MRI revealed a 6-cm intracranial lobulated mass in the posterior fossa with a(More)
Dear editor, We would like to present a case of brain abscess that developed in a 47 year-old male shortly after recurrent gastroscopies for the ligation of actively bleeding esophageal varicose veins. The patient was first admitted due to acute hematemesis and an episode of melena for the first time in his life. An emergency gastroscopy was done, which(More)
Fifty-two samples of pediatric low-grade glioma (48 primary, 4 recurrent) were analyzed for BRAF copy number variation (digital PCR analysis, CopyCaller) and point mutations of BRAF V600E, and exon 5 Q209 in GNAQ, and GNA11, using the MALDI-TOF mass spectrometer with validation by direct sequencing. An increased BRAF copy number was found in 18/47 primary(More)
