Ohtahara syndrome associated with hemimegalencephaly and intracranial lipoma.

Abstract: Hemimegalencephaly is a disorder of cortical malformation and is associated with various disorders including various neurocutaneous syndromes and many seizure types. We present a case of hemimegalencephaly associated with Ohtahara syndrome and intracranial and facial lipoma.

Ruptured intracranial lipoma--a Fatty outburst in the brain.

Abstract: Intracranial lipomas are rare congenital lesions that occur because of abnormal differentiation of embryogenic meninges. These lipomas are usually seen incidentally on brain imaging performed for another reason, and they are usually asymptomatic and do not require treatment. We present a case of ruptured intracranial lipoma, discovered in an elderly patient presenting with dizziness and after falling.

Co-occurrence of thoracolumbar intramedullary lipoma and intracranial lipoma during Gardner's syndrome: a rare occurrence.

Abstract: Dear Editor, It was with great interest that we read the paper by Kabir et al [3] and the related papers regarding spinal cord lipomas in Acta Neurochirurgica True intramedullary lipomas of the spinal cord are extremely rare mass lesions that have been reported only as single-case presentations [3, 4] Intracranial lipomas are also rare, as their spinal counterparts constitute less than 1 % of intracranial mass-occupying lesions [8] Herein, we report on a rare case of a thoraco lumbar in t ramedul la ry l ipoma wi th an accompanying intracranial lipoma on the background of Gardner’s syndrome (GS) A 50-year-old woman undergoing regular follow-up examinations due to GS was admitted to our institution with numbness in both legs and difficulty walking Her medical history described left-sided facial asymmetry because of a known osteoma (Fig 1) as well as epilepsy controlled with diphenylhydantoin sodium (100 mg/day) A cranial computed tomography (CT) revealed a large lipoma in the middle cranial fossa and in both cerebellopontine angles (Fig 2a) A lumbar CT and magnetic resonance imaging (MRI) revealed a giant intramedullary lipoma measuring 13 cm in the craniocaudal direction involving the thoracolumbar cord, which caused a tethered cord (Fig 2b–d) The neurosurgeon recommended a surgical operation after reviewing the radiological findings However, due to the patient’s recurrent surgical procedures and persistent desmoid tumour history in the old abdominal surgical site, she refused the surgical procedure The patient is still receiving follow-up care, taking anti-epileptic medication and undergoing regular radiological scans GS, a variant of familial adenomatous polyposis, is characterised by intestinal polyposis, desmoid tumours, osteomas, epidermoid cysts, dental abnormalities and periampullary carcinomas [2] Countless polyps in the colon are associated with a predisposition to develop colon cancer; if the colon is not totally removed, a total proctocolectomy is required in patients diagnosed with GS GS is rarely associated Electronic supplementary material The online version of this article (doi:101007/s00701-015-2456-y) contains supplementary material, which is available to authorized users

PET-CT visualization of intracranial lipomas

Abstract: Intracranial lipomas are rare lesions, infrequently indicated for neurosurgical treatment due to their benign course and significant surgery-related complications rate. The aim of this study was to collect, describe and analyze the patients with intracranial lipomas verified by PET-CT and reported in the literature up to date. The literature search was performed through Pub Med using the combination of the terms intracranial lipomas, CT, MRI and PET-CT. The thorough review of the relevant papers did not find even one case with PET-CT images of intracranial lipomas. The first two personal illustrative cases were demonstrated by our report. The value of PET-CT in the primary and differential diagnosis of intracranial lipomas was analyzed, in comparison with CT, MRI and PET-MRI.

Anesthesia management in rare case of beta thalassemia major patient under craniotomy for intracranial lipomas

Abstract: Aim and background: Beta thalassemia major is a hematologic autosomal recessive syndrome. Many anesthetic problems were noted in these patients like difficult intubation, coagulopathies and cardiomyopathies. In this case report, we describe a patient with Beta thalassemia major and intra cranial lipoma. case report: A 36 year old woman, known case of Beta thalassemia major, was candidate for elective craniotomy for intracranial lipoma. She had marked deformities in maxillofacial bones and it caused difficult intubation. For this reason intubation was performed with fiber optic laryngoscope. Beta thalassemia major patients have difficult air way because of hypertrophic bone marrow due to marked facial and mandibular bone deformities and we must consider these problems for anesthesia management.

Teaching NeuroImages: Striatocapsular infarct presumed due to intracranial lipoma

Abstract: A 27-year-old woman with no known risk factors for stroke presented with right hemiparesis. There was infarction of left corpus striatum on brain CT and MRI (figure 1). Imaging also showed an intracranial lipoma adjacent to the middle cerebral artery (MCA) (figure 2).

Mimics and diagnostic pitfalls of intracranial lesions in conventional MRI Imaging: Clues on Advanced MRI.

Abstract: Objective: To delineate and differentiate between late subacute hemorrhage and intracranial lipomas in clinically available conventional and advanced MR sequences. Methods: Two cases of late subacute hemorrhage and two cases of intracranial lipoma were reviewed with CT scans and 3.0T scanner MRI. The sequences evaluated in MRI were T1-weighted (T1W) fast spin echo (FSE), T2-weighted (T2W) FSE, gradient echo T2*-weighted (GRE T2*W) images, diffusion weighted (DWI), apparent diffusion coefficient (ADC) and multivoxel spectroscopy. Results: Late subacute hemorrhage and intracranial lipoma have similar imaging features on T1W, T2W FSE with blooming artefact at the margins on GRE T2*W. However on GRE T2*W sequence, the central area of lipoma demonstrates low signal; while hemorrhage demonstrates high signal. In DWI, late subacute hemorrhage shows hyperintensity; while in lipoma there is loss of signal. Conclusion: Awareness of the potential pitfalls in standard sequence are important, as these entities appear to have similar T1W/ T2W characteristic with blooming artefact on T2*W. Knowing the distinctive central signal intensity pattern on GRE T2W* and DWI is therefore essential to differentiate between these lesions as there are differences to their clinical management.
