Third Ventricular Glioblastoma Multiforme: Case Report and Literature Review.

ABSTRACT: Background Glioblastoma multiforme (GBM) typically presents in the supratentorial white matter, commonly within the centrum semiovale as a ring-enhancing lesion with areas of necrosis. An atypical presentation of this lesion, both anatomically as well as radiographically, is significant and must be part of the differential for a neoplasm in this anatomical location. Case Description We present a case of a 62-year-old woman with headaches, increasing somnolence, and cognitive decline for several weeks. Magnetic resonance imaging demonstrated mild left ventricular dilatation with a well-marginated, homogeneous, and nonhemorrhagic lesion located at the ceiling of the third ventricle within the junction of the septum pellucidum and fornix, without exhibiting the typical radiographic features of hemorrhage or necrosis. Final pathology reports confirmed the diagnosis of GBM. Conclusion This case report describes an unusual location for the most common primary brain neoplasm. Moreover, this case identifies the origin of a GBM related to the paracentral ventricular structures infiltrating the body of the fornix and leaves of the septum pellucidum. To our knowledge this report is the first reported case of a GBM found in this anatomical location with an entirely atypical radiographic presentation.

Project description:IntroductionTo investigate the clinical features, pregnancy care, timing, and approaches of pregnancy termination as well as the perinatal management of pregnant women with ectopic pheochromocytomas (EPCC) (paragangliomas, PGL).MethodsWe report the diagnosis and treatment of a pregnant women with EPCC which was confirmed in the third trimester in our hospital. Literature in relation to EPCC during pregnancy both in and outside China was searched for data analysis such as maternal clinical features and maternal and fetal prognosis.ResultsA total of 20 papers including 21 cases (plus ours) were retrieved. The average age of pregnant patients was 28 years old (from 21 to 37). Two patients presented no hypertension. Nineteen had hypertension in various extent with the accompany of headache (11 cases, 57.9%), palpitations (8 cases, 42.1%), sweating (6 cases, 31.6%), nausea (6 cases), abdominal pain (2 cases), etc. The tumor was found in the chest in 3 patients, in the upper abdomen in 1 patient, in the middle abdomen in 10 patients, between the lower abdomen and pelvic cavity in 3 patients and in the pelvic cavity in 3 patients. Five patients had a surgical removal of the tumor before delivery, 3 during cesarean section and 10 after giving birth.ConclusionEPCC (PGL) during pregnancy is a rare extra-adrenal tumor, whose manifestations are often confused with those of pregnancy-induced hypertension. It is extremely hard to diagnosis the disease before surgery. Patients still have an opportunity of undergoing spontaneous delivery if their tumors have been removed before labor. However, for patients whose pheochromocytomas is localized before labor, it is better to terminate their pregnancy via cesarean section in a proper time according to their obstetric conditions, while under the supervision of multidisciplinary specialists. The preparations of both α and β adrenergic receptor blocker treatment that is normally carried out before PGL removal surgery are unnecessary to be overemphasized before the cesarean section.
