Adiposity and meningioma

Melina Arnold, Andrew G Renehan, Graham A Colditz
For over a decade, excess body weight, commonly categorized as overweight (body mass index, BMI: 25.0 to 29.9 kg/m2) and obesity (BMI: ≥ 30 kg/m2) has been an established incidence risk factor for several adult cancers (1). For 2012, the burden of disease attributed to elevated BMI was estimated as nearly half-million new cancers worldwide, making this the third highest ranked cancer risk factor globally after smoking and infections (ranked second in most western populations) and an important public health problem (2, 3)...

BACKGROUND: Meningioma is a frequent primary intracranial tumor, the etiology of which is potentially related to adiposity. Metabolic syndrome (MetS) is an increasingly common disease characterized by having at least three of the following conditions: central adiposity, arterial hypertension, dyslipidemia, and insulin resistance. Only one prior study investigated MetS in relation to meningioma risk and found a positive association between the two. RESULTS: Among 2,027 cases and 20,269 controls, body mass index was positively associated with meningioma (p-value for trend < 0...

OBJECTIVE: Whether adiposity and lack of physical activity affect the risk for developing meningioma and glioma is poorly understood. Our objective was to characterize these associations in detail. METHODS: We conducted a systematic review and meta-analysis of adiposity and physical activity in relation to meningioma and glioma using cohort and case-control studies published through February 2015. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

BACKGROUND: Problem of closure of skull base defects after removal of craniobasal lesions, especially, craniofacial, is one of the most challenging in neurosurgery. Persistent skull base defect produces extremely high risk of cerebrospinal fluid leaks and consecutive infectious complications. Local pedicled grafts are the preferred material for plasty. In this study, the authors present original technique of using a pedicled buccal fat pad (BFP) graft. Anatomy and functions of BFP are discussed in details as well as surgical technique illustrated by 2 case reports...

BACKGROUND: The use of an autologous free fat graft is a widely applied technique to obliterate dead space and reinforce dural closure during skull base reconstructions. The associated complications and outcomes of this practice have not been studied. Dissemination of fat in the subarachnoid space resulting in lipoid meningitis has been reported after translabyrinthine approaches, and leakage of liquefied fat is seldom reported in the literature. This study aims to evaluate the morbidity associated with the usage of autologous fat graft in reconstruction of skull base defects based on an extensive experience...

Neoplasms of the nervous system, whether spontaneous or induced, are infrequent in laboratory rodents and very rare in other laboratory animal species. The morphology of neural tumors depends on the intrinsic functions and properties of the cell type, the interactions between the neoplasm and surrounding normal tissue, and regressive changes. The incidence of neural neoplasms varies with sex, location, and age of tumor onset. Although the onset of spontaneous tumor development cannot be established in routine oncogenicity studies, calculations using the time of diagnosis (day of death) have revealed significant differences in tumor biology among different rat strains...

Intracranial chondromas are uncommon benign lesions usually attached to dura and located over the convexity of the skull. Osteochondromas are even rarer and additionally contain a benign bony component. Both lesions are reportedly difficult to distinguish from meningiomas on pre-operative neuroimaging studies, although few detailed pathologic-neuroimaging correlation studies have appeared in the literature, particularly for intracranial osteochondromas. A 33-year-old woman with a 4-year history of headaches presented with recent onset of left-sided muscle spasms and weakness...

Following extensive suprasellar operations for excision of hypothalamic tumors, some patients develop morbid obesity, the so-called hypothalamic obesity (HyOb). HyOb complicates disorders related to the hypothalamus, including those that cause structural damage to the hypothalamus, pituitary macroadenoma with suprasellar extension, glioma, meningioma, teratoma, germ cell tumors, radiotherapy, Prader-Willi syndrome, and mutations in leptin, leptin receptor, POMC, MC4R and CART genes. It is conceivable that a subgroup of patients with 'simple obesity' also have HyOb...

OBJECTIVE: We describe an intraosseous angiolipoma of the cranium and discuss the outcome. Angiolipomas are benign tumors that consist of mature adipose tissue and abnormal vessels. They occur predominantly in the subcutaneous tissue of the trunk and upper limbs. Only 4 examples of intraosseous angiolipomas have been reported in the literature, all of which involved the mandible and ribs. CLINICAL PRESENTATION: A 39-year-old man presented with a right parietal swelling...

A 55-year-old man presented with a rare lipomatous meningioma associated with acute subdural hematoma manifesting as sudden onset of severe headache, but no neurological deficit. No evidence of trauma or underlying predisposition to hemorrhage was seen. Fluid-attenuated inversion-recovery magnetic resonance imaging showed a thin hyperintense area in the right temporal convexity, and an extra-axial mass appearing as mixed hypointensity and hyperintensity. Two weeks later, right temporal craniotomy was performed and the tumor was totally resected with the attached dura...

Epidural fat is a reservoir of lipophilic substances that cushions the pulsatile movements of the dural sac, protects nerve structures, and facilitates the movement of the dural sac over the periosteum of the spinal canal during flexion and extension. Excessive epidural fat can compress the underlying structures, however, and affect the placement of catheters and the distribution of injected solutions. This review discusses changes in epidural fat related to various diseases and events: lipomatosis, epidural lymphoma, arachnoid cysts, epidural hematoma, meningiomas, angiolipomas, spondylolysis, scoliosis, spinal stenosis, and liposarcoma...

Lipomatous meningiomas are rarely encountered and are included in the World Health Organization's (WHO) group of metaplastic meningiomas. We report two cases of these tumors. The presenting symptoms were headaches in one case and seizure in the other. Radiologically, these tumors were extra-axial and unique. One tumor displayed fat accumulation, while the other had the appearance of a conventional meningioma. Microscopically, these tumors corresponded to meningothelial and transitional meningiomas containing a variable proportion of adipose tissue composed of mature adipocytes or lipoblasts...

Meningiomas exhibit a broad spectrum of differentiation potency corresponding to different histological subtypes. The separate secretory or lipomatous transformation of meningothelial cells is uncommonly encountered in meningiomas classified into distinct secretory or lipomatous variants. The coexistence of these two different histological subtypes is extremely rare. We report an exceptional case of secretory meningioma associated with extensive lipomatous component in a 58-year-old woman. CT scan and MRI of the brain showed a well-defined tumor mass in the right temporal lobe with areas of adipose tissue and extensive surrounding brain edema...

'Classical' genomic progesterone receptors appear relatively late in phylogenesis, i.e. it is only in birds and mammals that they are detectable. In the different species, they mediate manifold effects regarding the differentiation of target organ functions, mainly in the reproductive system. Surprisingly, we know little about the physiology, endocrinology, and pharmacology of progesterone and progestins in male gender or men respectively, despite the fact that, as to progesterone secretion and serum progesterone levels, there are no great quantitative differences between men and women (at least outside the luteal phase)...

Werner syndrome is a rare autosomal recessive disorder characterized by clinical signs of premature aging, short stature, scleroderma-like skin changes, endocrine abnormalities, cataracts, and an increased incidence of malignancies. We report on a 48-year-old woman with Werner syndrome associated with intracranial meningiomas who had extensive musculoskeletal manifestations including osteoporosis of the extremities, extensive tendinopathy about the ankles, osteomyelitis of the phalanges of the first left toe, abundant soft-tissue calcification, and two dense ossified soft-tissue masses, with cortical bone and trabeculae arising from the posterosuperior aspect of the calcanei and extending into Kager fat pads...

Meningiomas are slow-growing benign brain tumors. The etiology of meningioma is largely unknown, and exposure to high-dose ionizing radiation and coexistence with certain rare genetic conditions explain only a small fraction of the incidence of the disease. The evidence that implicates gender-specific hormones in the pathogenesis of meningioma emanates from data showing increased growth of meningiomas during pregnancy and change in size during menses. Observational data have identified the menopause and oophorectomy as conferring protection against the risk of developing meningiomas, while adiposity is positively associated with the disease...

We present a case of histologically confirmed lipomeningioma, the first to our knowledge reported in Australia. A 61-year-old man presented with seizures and confusion, and was found to have a non-enhancing left extra axial temporo-parietal lesion on CT and MRI scan. On MRI, the mass lesion showed hyper-intensity on the T1 weighted images, hypo-intensity on fat suppressed T2 weighted images and no enhancement with intravenous gadolinium, indicating a mass consisting predominantly of fatty tissue. A subsequent CT also showed the mass lesion to be hypodense with Hounsfield units indicating fatty tissue...

CONTEXT: Lipochoristomas (lipomatous choristomas) are rare tumors of the acoustic nerve (cranial nerve VIII/vestibulocochlear nerve) within the internal acoustic canal and sometimes the cerebellopontine angle, and are histogenetically believed to be congenital malformations. Their clinically indolent behavior has recently prompted a more conservative management protocol in a quest for maximal nerve/hearing preservation. This approach contrasts sharply with that for the common internal acoustic canal/cerebellopontine angle tumors, the neuroepithelial neoplasms (acoustic schwannomas and meningiomas), which behave more aggressively and have more prominent clinical manifestations...
