1/105. Cranio-cerebral erosion: delayed diagnosis and treatment.Cranio-cerebral erosion is a well-known complication of calvarian fracture with underlying dural tear and cerebral injury in infancy and early childhood. The anatomy, pathogenesis and natural evolution of these lesions remain obscure. The common clinical symptoms are seizures, focal neurological deficits, impairment of consciousness and a soft subgaleal mass. Three patients of cranio-cerebral erosion who underwent delayed surgery in their adult lives are presented to illustrate the common and uncommon features, and their long-term outcome is discussed.- - - - - - - - - - ranking = 1keywords = seizure, focal (Clic here for more details about this article) |
2/105. Reactivation of herpes virus after surgery for epilepsy in a pediatric patient with mesial temporal sclerosis: case report.OBJECTIVE: This case report is presented to raise the awareness of the potential risk of reactivation of herpes simplex virus (HSV) encephalitis after intracranial surgery. CLINICAL PRESENTATION: The case of an 8-year-old male patient who suffered a reactivation of HSV encephalitis after undergoing amygdalohippocampectomy for complex partial seizures is reported. This patient had previously contracted HSV 1 meningoencephalitis at the age of 16 months. Six years later, a left amygdalohippocampectomy was proposed after the development of intractable partial epilepsy associated with left mesial temporal lesions. During the postoperative period, the patient suffered severe clinical deterioration with partial status epilepticus, aphasia, and hyperthermia, which resolved after intensive antiepileptic treatment supported by acyclovir. CONCLUSION: We advise prophylactic pre-, peri-, and postoperative treatment with acyclovir for patients with known histories of HSV encephalitis who undergo intracranial procedures.- - - - - - - - - - ranking = 88.479243481943keywords = epilepsy, partial seizure, seizure, simple (Clic here for more details about this article) |
3/105. Idiopathic retroperitoneal fibrosis in multifocal fibrosclerosis.A case of rare combination of retroperitoneal fibrosis and Riedel's thyroiditis is presented. The term multifocal fibrosclerosis is used in the literature to denote such combination and others which include idiopathic retroperitoneal fibrosis, mediastinal fibrosis, sclerosing cholangitis, invasive (Riedel's) thyroiditis and pseudotumor of the orbit.- - - - - - - - - - ranking = 0.095534579123424keywords = focal (Clic here for more details about this article) |
4/105. Systemic multifocal fibrosclerosis.We describe a case of hydronephrosis as a result of retroperitoneal fibrosis in a patient who had previous sclerosing lobulitis of the breast. To the best of our knowledge this is the first reported association between these two conditions in the english literature. We presume these conditions are linked and unify them under the general heading of systemic multifocal fibrosclerosis.- - - - - - - - - - ranking = 0.095534579123424keywords = focal (Clic here for more details about this article) |
5/105. A case of renal pseudotumor associated with chronic pachymeningitis.BACKGROUND: A 56-year-old woman was referred to our hospital with a left renal mass. methods/RESULTS: Radiologic studies demonstrated a solitary space-occupying lesion in the left kidney and a malignant tumor was suspected. Left radical nephrectomy was then performed. Pathological examination revealed a sclerotic fibrous lesion with a rather distinct margin and no evidence of malignancy. These pathological findings were consistent with the diagnosis of a renal pseudotumor. CONCLUSIONS: This patient had a history of chronic pachymeningitis that formed a thoracic epidural focus causing spinal cord compression and the histologic appearance of this focus was similar to the renal lesion. It was concluded that this was a rare case of a renal pseudotumor associated with multifocal fibrosclerosis.- - - - - - - - - - ranking = 0.019106915824685keywords = focal (Clic here for more details about this article) |
6/105. Early childhood MRI findings in complex partial seizures and hippocampal sclerosis.magnetic resonance imaging (MRI) was performed on an infant with typical complex partial seizures. Visual analysis revealed MRI signs of left hippocampal sclerosis (HS) at an age of 9 months. Morphometric data including volumetry and relaxometry confirming the diagnosis are shown. This is the first report of an infant younger than 2 years with typical MRI findings including morphometric data on HS.- - - - - - - - - - ranking = 56.325953325308keywords = partial seizure, seizure (Clic here for more details about this article) |
7/105. Hippocampal sclerosis with hypertrophy of end folium pyramidal cells.Mesial temporal lobectomy for the treatment of intractable temporal lobe seizures may show dual pathologies for example hippocampal sclerosis (HCS) combined with a malformation. In a lobectomy specimen from a 40-year-old female with typical radiological and pathological features of HCS, an additional histopathological finding was the presence of hypertrophic pyramidal cells in the dentate hilus, in which cytoplasmic accumulations of phosphorylated neurofilament were demonstrated. Although these cells closely resembled dysplastic nerve cells of cortical dysplasia, we argue that the cytoskeletal abnormalities observed are a result of ongoing alterations to hippocampal circuitry in an evolving HCS.- - - - - - - - - - ranking = 0.98089308417532keywords = seizure (Clic here for more details about this article) |
8/105. Chronic sclerosing sialadenitis of the submandibular gland associated with idiopathic retroperitoneal fibrosis.We report a case of a 57-year-old man who developed a fibrosclerosing lesion in the submandibular gland and idiopathic retroperitoneal fibrosis (IRF) involving the unilateral periureteral region within a year. Both lesions were resected surgically because of the suspicion of neoplasm. Pathologic examination revealed similar histologic and immunohistochemical features for both lesions, namely, fibrosclerosis with prominent hyalinizing collagen bundles and proliferation of myofibroblastic cells, and a non-neoplastic reactive nature. There was infiltration by lymphocytes with prominent lymph follicles, plasma cells and macrophages. The histologic and immunohistochemical findings suggest that the two lesions were of a similar pathogenesis, which was possibly mediated by macrophages. We think that the present case may be an unusual form of multifocal fibrosclerosis. Although sialolithiasis is thought to be a major pathogenic factor for chronic sclerosing sialadenitis of the submandibular gland, the present case suggests that certain cases might have an etiology similar to IRF.- - - - - - - - - - ranking = 0.019106915824685keywords = focal (Clic here for more details about this article) |
9/105. White-matter change in mesial temporal sclerosis: correlation of MRI with PET, pathology, and clinical features.PURPOSE: To assess the magnetic resonance imaging (MRI), positron emission tomography (PET), pathology, and clinical findings of patients with the MRI feature of white-matter change (WMC) in the anterior temporal lobe. methods: Fifty-six patients with pathologically proven mesial temporal sclerosis were included in this study. MRI and 18F-2-deoxyglucose-(FDG) PET images were obtained before surgery in all patients. The patients were divided into two groups according to the presence of WMC on their MRI. WMC consists of an indistinct gray-white matter demarcation and an increased signal intensity of the anterior temporal lobe on T2-weighted images. The two groups were then compared in terms of MRI, PET, pathology, and clinical features. RESULTS: The MRI feature of WMC was observed in 18 (32%) of the 56 patients. PET images of those patients revealed more severe hypometabolism of the ipsilateral temporal lobes (p< 0.05). In terms of histologic findings, larger numbers of heterotopic neurons were observed in the anterior temporal lobe white matter of these patients who also shared the following clinical features: earlier seizure onset, frequent history of febrile convulsions, and favorable surgical outcomes. CONCLUSIONS: The MRI feature of WMC is an additive sign for correct seizure lateralization and may be related to a favorable surgical outcome in patients with temporal lobe epilepsy.- - - - - - - - - - ranking = 17.403181523805keywords = epilepsy, seizure (Clic here for more details about this article) |
10/105. Ictal vomiting in partial seizures of temporal lobe origin.We report 3 cases presenting ictal vomiting during partial seizures of temporal lobe origin. Two patients had complex partial seizures accompanying vomiting characteristics. Ictal vomiting occurred early in the course of the seizure when rhythmic discharges involved predominantly the left hemisphere, the language dominance hemisphere. The other patient had ictal vomiting in simple partial seizures which originated from the right temporal lobe or the language nondominant side. All 3 patients underwent anterior temporal lobectomy with promising outcomes. Pathologic diagnosis included hippocampal sclerosis in 2 patients and astrocytoma in 1 patient. In our patients, ictal vomiting does not lateralize temporal lobe epilepsy and is not specific to pathology.- - - - - - - - - - ranking = 95.28569913467keywords = epilepsy, partial seizure, seizure, simple (Clic here for more details about this article) |
