A case of prenatal diagnosis of the corpus callosum lipoma at 32–33 weeks of gestation is presented. In a consultative examination, a hyperechoic formation with clear contours was found in the projection of the septum pellucidum, occupying the rostrum, genu, and truncus of corpus callosum, without signs of intratumorally blood flow in the color Doppler mapping mode. The prenatal diagnosis of "callosum lipoma" was established, confirmed after the birth of a child during magnetic resonance imaging.

Abstract Objective To the best of our knowledge, there have not been studies to address the issue of long-term follow-up of patients with prenatal diagnosis of isolated complete septum pellucidum agenesis (SPA). The aim of this study was to acquire information about the school-age outcome of such patients as a resource for counseling parents receiving this prenatal finding. Methods From a large fetal magnetic resonance (MR) database, we selected only those cases with isolated complete SPA as confirmed by two senior pediatric neuroradiologists in consensus; we then gathered information from the parents of those children who had reached the school age. Results None among the 12 cases (mean age at follow-up: 8.7 years, range: 6–13 year) of the resulting final cohort presented visual or stature deficits; only one required special teaching assistance in school. All other 11 children resulted without any notable academic issue. Conclusion Our report may provide information of practical value about the school-age outcome of fetuses detected by prenatal MR imaging to carry isolated complete SPA.

SynopsisMany structural brain abnormalities have been described in schizophrenia, consistent with a neurodevelopmental model for this disease. We report here a study of the cavum septum pellucidum (CSP) in schizophrenia compared to control groups, as well as the clinical correlates of this congenital anomaly in schizophrenia. We conducted a magnetic resonance imaging (MRI) study to compare rates of CSP in schizophrenia (N = 67) v. psychiatric controls (bipolar and schizoaffective, N = 60) and healthy controls (N = 37). Of the controls 18·9 %, and of all psychotic subjects 18·1 % had a CSP of any size and there was no difference in the frequency of large CSP among the groups. Males had higher rates of CSP than females (25% v. 9·7%, P = 0·01) in all groups. Schizophrenics had higher CSP rates than affective patients (25%, v. 10%, P = 0·02). No clinical difference was found between schizophrenics with or without CSP.

Abstract OBJECTIVE: Ten rare cases of symptomatic septum pellucidum cysts in patients who underwent endoscopic fenestration are described. The approaches and techniques used in the management of these cysts and the endoscopic surgical indications are discussed. CLINICAL PRESENTATION: In the past 5 years, 10 patients (age range, 3–60 yr) with symptomatic septum pellucidum cysts underwent neuroendoscopic fenestration. The most common symptom was intermittent headache (seven patients) accompanied by dizziness, vomiting, and epileptic seizures. Two patients presented with epileptic seizures. One patient presented with abnormally increased head circumference. Magnetic resonance imaging scans of 10 patients showed septum pellucidum cysts, two with hydrocephalus, and two with pituitary microadenoma. INTERVENTION: All 10 patients underwent endoscopic fenestration with a rigid endoscope via a frontal approach. Eight cases were performed freehand. Two cases were assisted by a frameless neuronavigation system. Postoperatively, the mass effect of the cysts and the symptoms resolved immediately, and computed tomographic or magnetic resonance imaging scans showed significant decrease in the cyst size and no recurrence during follow-up. Ventricular sizes in the two patients with hydrocephalus were normal. CONCLUSION: Neuroendoscopic pellucidotomy could be an effective, safe, and convenient therapeutic method for symptomatic septum pellucidum cysts. This approach might provide communication between the cyst and the ventricular system, thus avoiding shunting or craniotomy. We consider that it is appropriate to use the rigid endoscope via the frontal approach. It is helpful to fill the ventricles with lactated Ringer's solution and leave an external drain after surgery.

Absent Septum Pellucidum

Improved fetal imaging has resulted in increased diagnosis of isolated absent septum pellucidum without other intracranial abnormalities. There is little literature regarding outcomes for these fetuses. This study hypothesized the majority of infants diagnosed by fetal magnetic resonance imaging (MRI) with isolated absent septum pellucidum would retain this diagnosis postnatally. Specifically, in the absence of postnatal endocrine or ophthalmologic abnormalities, postnatal imaging would find no additional related findings, and fetuses would be at low risk for developmental delay. Two of 8 subjects met postnatal criteria for septo-optic dysplasia; remaining subjects had normal postnatal endocrine and ophthalmologic evaluations and no significant related findings on postnatal MRI. One subject without septo-optic dysplasia had delays on developmental screening; all others had normal screening (range of follow-up 8-72 months). Our study questions the necessity of postnatal imaging for prenatally diagnosed isolated absent septum pellucidum. Majority of fetuses with isolated absent septum pellucidum retained this diagnosis postnatally.

Cavum Septum Pellucidum

Abstract Background Chronic traumatic encephalopathy (CTE), a neurodegenerative tauopathy, cannot currently be diagnosed during life. Atrophy patterns on magnetic resonance imaging could be an effective in vivo biomarker of CTE, but have not been characterized. Mechanisms of neurodegeneration in CTE are unknown. Here, we characterized macrostructural magnetic resonance imaging features of brain donors with autopsy-confirmed CTE. The association between hyperphosphorylated tau (p-tau) and atrophy on magnetic resonance imaging was examined. Methods Magnetic resonance imaging scans were obtained by medical record requests for 55 deceased symptomatic men with autopsy-confirmed CTE and 31 men (n = 11 deceased) with normal cognition at the time of the scan, all >60 years Three neuroradiologists visually rated regional atrophy and microvascular disease (0 [none]–4 [severe]), microbleeds, and cavum septum pellucidum presence. Neuropathologists rated tau severity and atrophy at autopsy using semi-quantitative scales. Results Compared to unimpaired males, donors with CTE (45/55=stage III/IV) had greater atrophy of the orbital-frontal (mean diff.=1.29), dorsolateral frontal (mean diff.=1.31), superior frontal (mean diff.=1.05), anterior temporal (mean diff.=1.57), and medial temporal lobes (mean diff.=1.60), and larger lateral (mean diff.=1.72) and third (mean diff.=0.80) ventricles, controlling for age at scan (ps<0.05). There were no effects for posterior atrophy or microvascular disease. Donors with CTE had increased odds of a cavum septum pellucidum (OR = 6.7, p < 0.05). Among donors with CTE, greater tau severity across 14 regions corresponded to greater atrophy on magnetic resonance imaging (beta = 0.68, p < 0.01). Conclusions These findings support frontal-temporal atrophy as a magnetic resonance imaging finding of CTE and show p-tau accumulation is associated with atrophy in CTE.
