Intracranial lipoma

Sunita Singh, Promil Jain, Hemant Yadav, Ishwar Singh, Rajeev Sen
Dermoid cyst is a congenital lesion that arises due to embryogenic impairment. It accounts for less than 0.3% of all intracranial masses. Herein we report a 30-year-old male who presented with a short history of headache and behavioral disorder. Physical and radiological examination diagnosed it to be a lipoma/epidermoid arising from corpus callosum. The lesion was removed endoscopically and histopathologic examination was performed which confirmed it to be a dermoid cyst. Rarity of the lesion and difficulty in pre-operative diagnosis prompted us to bring forward this case report...

Intramuscular lipomas are rare, benign, mesenchymal tumors occurring deep in the fascia, typically involving large muscle groups in adults. We report a case of an intramuscular lipoma occurring as a subcutaneous midline nasal mass in a 3-month-old infant. The differential diagnosis of a midline mass on the glabella of an infant is important and should include developmental anomalies such as nasal glioma, nasal dermoid cyst, and encephalocele, so neuroimaging is an essential first step in evaluating these lesions to exclude intracranial extension...

Haberland syndrome or Fishman syndrome also known as encephalocraniocutaneous lipomatosis (ECCL) is a rare, congenital neurocutaneous disorder. It is characterized by unilateral involvement of skin, eyes and central nervous system. We report the case of a 28-year-old woman who presented with soft lipomatous swelling over right temporal area with nonscarring alopecia of part of frontal and parietal region. The patient had a history of seizures and ipsilateral scleral dermoid. Computed tomography scan findings were suggestive of lipomas and calcification of falx...

The Klippel-Feil syndrome is a congenital malformation of the skull flap involving complex cervical vertebrae and organs, characterized by a classic triad: short neck, limitation of movement of the head due to cervical spine fusion and low hairline in occipital region. It results from an error in the axial skeleton segmentation of the embryo; its incidence is estimated at 1/40,000-42,000 births and predominates in females. The aim of this paper is to describe the clinical picture of a patient with Klippel-Feil syndrome and multiple malformations, including tracheoesophageal fistula, bifid thumb and intracranial lipomas/angiolipomas,that have not been previously described in the syndrome, so it is considered an exceptional finding...

PURPOSE: To report a rare case of encephalocraniocutaneous lipomatosis (ECCL) presented with characteristic multiple organ involvement. METHODS: A 7-day-old white Iranian girl was referred with ocular, skin and brain abnormalities. RESULTS: The findings of nevus psiloliparus, eyelid choristoma and intracranial lipoma were consistent with ECCL. CONCLUSION: Since the skin and ocular manifestations can be easily observed at birth examination, pediatricians and ophthalmologists should be aware of this condition...

Melanocytoma are the melanocytic tumors originating from leptomeningeal melanocytes. Melanocytomas are commonly seen in the central nervous system (CNS) and are often associated with neurocutaneous melanosis (NCM). However, simultaneous presentation of intra-axial and extracranial melanocytoma is a very rare event. Here, we report a unique case of 21-year-old male with intermediate-grade subcutaneous (SC) melanocytoma, mimicking lipoma, occurred synchronously with an intracranial melanocytoma, not associated with NCM...

The authors present a unique case of intracranial lipoma in the interpeduncular cistern associated with proximal P1 segment fenestration. This patient is a 20-year-old male with extensive psychiatric history and complaints of recent auditory hallucinations. Cranial magnetic resonance imaging (MRI) (T1, T2, and FLAIR) showed a hyperintense lesion in the left aspect of interpeduncular cistern with a prominent flow void within the hyperintense lesion suggestive of a combined vascular-lipomatous lesion. Computed tomography (CT) angiography showed a high-riding large tortuous P1 segment on the left side with proximal fenestration, the ectatic posteromedial limb harboring a fusiform dilated segment...

BACKGROUND: Pineal tumors are very uncommon intracranial lesions, and endodermal cysts in this location are extremely rare. CASE DESCRIPTION: A 49-year-old right-handed female presented with 3 weeks history of progressive dizziness and imbalance. Imaging studies showed 1.8 cm × 1.7 cm × 1.8 cm pineal lesion with small enhancing mural component displacing ventrally the quadrigeminal plate and narrowing of aqueduct of Sylvius without hydrocephalus. In addition, she was found with small interhemispheric lipoma, and small posterior falx possible meningioma...

Intracranial lipomas are rare developmental lesions, predominantly occurring in the interhemispheric location. Osteochondrolipoma is an extremely rare variant of lipoma with osseous and chondroid differentiation. We present a case of interhemispheric osteochondrolipoma, in a 2.5-years-old male child which was detected antenatally, in association with corpus callosum agenesis. The lesion progressively increased in size with resulting compression of surrounding structures, and was subjected to microsurgical decompression...

AIM: A pericallosal lipoma is a fat-containing lesion occurring in the interhemispheric fissure closely related to the corpus callosum, which is often abnormal. This is the most common location for an intracranial lipoma. In this study, we aim to report on the clinical and radiographic aspects of ten patients diagnosed with pericallosal lipomas. MATERIAL AND METHODS: A retrospective analysis of patients who presented to the neurology and neurosurgery outpatient clinics of Kayseri Training and Research Hospital between 2010 and 2014 revealed that 10 patients had the diagnosis of pericallosal lipoma...

Intracranial lipomas are rare congenital malformations. The most common type of intracranial lipoma is the interhemispheric lipoma, which is frequently associated with callosal anomalies such as hypogenesis or agenesis of the corpus callosum. In contrast, interhemispheric lipomas are less often accompanied with malformations of cortical development (MCD). We report magnetic resonance imaging findings of three infants with an interhemispheric lipoma, associated with a callosal anomaly, and MCD: two infants with nodular interhemispheric lipoma, agenesis of the corpus callosum, and polymicrogyria, and one infant with interhemispheric curvilinear lipoma, hypoplasia of the corpus callosum, and heterotopias...

Intradural lipomas are rare lesions, usually associated with spinal dysraphism, affecting the spinal cord. Intracranial lipomas make up less than 1% of intracranial tumours; only 13 cases of these lesions being located at the craniocervical junction are reported in the literature. These lesions tend to present with neurological deficits such as quadraparesis and incontinence. We present the first case of a successfully treated intradural lipoma at the foramen magnum in a 15-year-old girl who presented with classical Chiari symptoms and no neurological deficits...

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 represent a subgroup of intracranial lesions with unique characteristics and some imaging patterns that may facilitate the differential diagnosis...

Encephalocraniocutaneous lipomatosis (ECCL) is a rare congenital syndrome with an unknown etiology. Since 1970, around 60 cases have been reported in English literature. ECCL is usually classified by cutaneous lesions and non-progressive intracranial or spinal lipomas; however three cases of ECCL associated with low grade glioma (LGG) have been described. We report on the fourth case of LGG in a patient with ECCL; a grade II pilocytic astrocytoma with pilomyxoid features in a 3-month-old male, the youngest in literature...

Intracranial lipomas (ICLs) are rare lesions, the vast majority encountered as incidental findings on imaging studies. ICLs are generally pericallosal midline lesions and thought to be asymptomatic and can be accompanied by additional intracranial congenital malformations. We describe a 17-year old male with an unusual case of ICL on the frontal lobe associated with cortical dysplasia and abnormal vasculature mimicking arteriovenous malformation on magnetic resonance images.
