Brain tumors arising in the neonatal period are rare and diagnosis is usually delayed. We encountered a case of choroid plexus papilloma (CPP) in a term newborn infant. The sonographic findings of this case demonstrated a striking similarity to intraventricular hemorrhage, an entity commonly seen in premature infants. A preoperative diagnosis was made, however, with the application of the pulse...

Abstract INTRODUCTION Leptomeningeal metastases (LM) is a clinical complication that occurs when cancer cells invade the leptomeninges and cerebrospinal fluid of patients with malignant tumors. Once diagnosed, limited treatment options exist, survival poor. Rhenium-186 Nanoliposome (186RNL) liposomal encapsulated beta emitter short path length 1.8 mm, thereby allowing high specific activity bra...

Patients with large amounts of intraventricular blood have a poor prognosis. The question is whether the quantity of ventricular blood or other factors related to the origin of the intraventricular bleeding cause poor outcome. The association between ventricular blood volume and outcome was analysed in patients with a primary intraventricular haemorrhage (PIVH) and in patients with an aneurysma...

The present essay is illustrated with magnetic resonance images obtained at the authors' institution over the past 15 years and discusses the main imaging findings of intraventricular tumor-like lesions (colloid cyst, oligodendroglioma, astroblastoma, lipoma, cavernoma) and of inflammatory/infectious lesions (neurocysticercosis and an atypical presentation of neurohistoplasmosis). Such lesions ...

intraventricular hemorrhage (ivh) is one of the major causes of the cerebral palsy and mental retardation. prevention and early management of these neurologic developmental problems will require determining the perinatal risk factors associated with this clinical entity. pneumothorax increase the risk of ivh, and cause of pneumothorax has an important effect in severity of ivh. this is a prospe...

protein s (ps) is an antithrombotic plasma protein that plays essential roles in limiting thrombus formation in the anticoagulant system. protein s deficiency is related with recurrent thrombosis. here, the authors report a case of a term neonate with severe ps deficiency in year 2015, imam hospital, tehran, iran, that had seizures and intraventricular hemorrhage (ivh) since the age of 3 days. ...

This case report describes clinical, surgical, MR, and pathologic findings of an intraventricular fibroma, a rare, benign mesenchymal neoplasm. Relatively isointense with normal brain parenchyma on T1-weighted images, the tumor exhibited hyperintense signal on T2-weighted pulse sequences and enhanced intensely and homogeneously after intravenous administration of gadopentetate dimeglumine. Chor...

There are many kinds of extra-axial brain tumors and tumor-like lesions, and definitive diagnosis is complicated in some cases. In this pictorial essay, we present rare and challenging extra-axial brain lesions including neuroenteric cyst, primary leptomeningeal melanomatosis, isolated dural neurosarcoidosis, intradiploic epidermoid cyst, ruptured dermoid cyst, intraventricular cavernoma, and c...

A case of inflammatory pseudotumor is described, in which CT revealed a hyperdense intraventricular lesion with a trapped temporal horn, and MR imaging showed decreased T1 and markedly hypointense T2 signal with homogeneously intense enhancement. Radiologically and grossly the tumor resembled a meningioma; however, histologically it was composed purely of inflammatory, nonneoplastic components....
