Diffuse low-grade gliomas are rare primitive cerebral tumours of adults. These tumors progress continuously over time and then turn to a higher grade of malignancy associated with neurological disability, leading ultimately to death. Tumour size is one of the most important prognostic factors. Thus, it is of great importance to be able to assess the volume of the tumor during the patients' monitoring. MRI is nowadays the recommended modality to achieve this. Furthermore, if surgery remains the first option for diffuse low-grade gliomas, chemotherapy is increasingly used (before or after a possible surgery)...

The development of cutaneous sarcoidosis as a paradoxical adverse event of tumor necrosis factor alpha (TNF-α) blockers has been reported in the literature; however, an erythrodermic form of cutaneous sarcoidosis during anti-TNF-α therapy has not yet been reported. Herein, we report the first case of an erythrodermic form of cutaneous sarcoidosis during anti-TNF-α therapy and review previous studies of cutaneous sarcoidosis. A 6-year-old Korean girl who had been suffering from juvenile rheumatoid arthritis presented with generalized erythematous skin eruption involving more than about 90% of her body surface area...

Clara Haskil (January 7, 1895-December 7, 1960) was one of the most famous female pianists of the 20th century. In her life and work she set new standards in piano playing. However, her career was beset by poor health and the adversities of two world wars. In her lifetime Haskil had three major disorders: juvenile scoliosis requiring treatment in her adolescence, a tumor of the sellar region requiring surgery at age 47 years, and a traumatic brain injury causing her death at the age of 65. Her medical history illustrates the development of surgical methods and rehabilitation in medicine before and after World War II...

Extracellular tumors found with the spermatic cord, known as neoplasms, are usually identified to be benign. However, the accurate and timely diagnosis of spermatic cord masses is highly crucial, especially when most results are often overlooked or unclear. In this review, we discuss the anatomy and embryology of the spermatic cord. Upon rooting these fundamental concepts, we discuss an array of benign and malignant neoplastic tumors, including their origin, pathological features, clinical evaluation and management, as well as other case-specific characteristics of unique presentation...

Metastasis to the pineal region is a rare event, and esophageal adenocarcinoma metastatic to the pineal region is exceptionally rare, with only two cases reported in the current literature. Here, we characterize a third case of metastatic esophageal adenocarcinoma to the pineal region, and compare clinicopathological characteristics among all three cases. The three patients were men, with ages at neurological presentation ranging from 48 to 65years. Time from initial esophageal adenocarcinoma diagnosis to development of neurologic symptoms ranged from 12 to 23months...

Leptomeningeal disease (LMD) represents disseminated intracranial metastatic disease that requires early detection and initiation of therapy. Patients with LMD typically present with a variety of neurologic problems, including ocular disturbances. However, little is reported on LMD presenting exclusively with ocular-related disturbances in the absence of any other central nervous system (CNS) dysfunction. Our goal was to describe the workup for ocular disturbances in the setting of known cancer diagnosis. Retrospective case study utilizing prospectively collected database at a tertiary cancer care center for all patients with diagnosis of LMD between 2001 and 2009...

Glioblastoma (GBM) is the most aggressive type of brain tumor. In this context, animal models represent excellent tools for the early detection and longitudinal mapping of neuronal dysfunction, that are critical in the preclinical validation of new therapeutic strategies. In a mouse glioma model, we developed sensitive behavioral readouts that allow early recognizing and following neurological symptoms. We injected GL261 cells into the primary motor cortex of syngenic mice and we used a battery of behavioral tests to longitudinally monitor the dysfunction induced by tumor growth...

Tuberous sclerosis complex (TSC) is an autosomal dominantly inherited disorder with variable expressivity associated with hamartomatous tumors, abnormalities of the skin, and neurologic problems including seizures, intellectual disability, and autism. TSC is caused by pathogenic variants in either TSC1 or TSC2. In general, TSC2 pathogenic variants are associated with a more severe phenotype than TSC1 pathogenic variants. Here, we report a pathogenic TSC2 variant, c.1864C>T, p.(Arg622Trp), associated with a mild phenotype, with most carriers meeting fewer than two major clinical diagnostic criteria for TSC...

Upregulation of the pro-inflammatory cytokine tumor necrosis factor α (TNF-α) is involved in the development and progression of numerous neurological disorders. Recent reports have challenged the concept that TNF-α exhibits only deleterious effects of pro-inflammatory destruction, and have raised the awareness that it may play a beneficial role in neuronal growth and function in particular conditions, which prompts us to further investigate the role of this cytokine. Insulin-like growth factor-1 (IGF-1) is a cytokine possessing powerful neuroprotective effects in promoting neuronal survival, neuronal differentiation, neurite elongation, and neurite regeneration...

: Thyroid cancer with cranial metastasis in a pregnant woman is very rare. In the literature, most cases are diagnosed early from neurogenic signs or symptomatic thyroid gland. Pregnancy also contributes to a hesitation toward early surgical and medical treatments. We reported a scalp tumor in a physically healthy 37-year-old pregnant female with a follicular thyroid carcinoma (FTC) with lung, bone and cranial metastasis in initial presentation. Silent neurogenic and physical examinations make an early diagnosis very challenging...

Several monogenic causes of familial myelodysplastic syndrome (MDS) have recently been identified. We studied two families with cytopenia, predisposition to MDS with chromosome 7 aberrations, immunodeficiency, and progressive cerebellar dysfunction. Genetic studies uncovered heterozygous missense mutations in SAMD9L, a tumor suppressor gene located on chromosome arm 7q. Consistent with a gain-of-function effect, ectopic expression of the two identified SAMD9L mutants decreased cell proliferation relative to wild-type protein...

Juvenile angiofibroma is an uncommon, benign, locally aggressive vascular tumor. It is found almost exclusively in young men. Common presenting symptoms include nasal obstruction and epistaxis. More advanced tumors may present with facial swelling and visual or neurological disturbances. The evaluation of patients with juvenile angiofibroma relies on diagnostic imaging. Preoperative biopsy is not recommended. The mainstay of treatment is resection combined with preoperative embolization. Endoscopic surgery is the approach of choice in early stages, whereas, in advanced stages, open or endoscopic approaches are feasible in expert hands...

BACKGROUND: Pilocytic astrocytomas (PAs) are slow growing neoplasms and usually located at the cerebellum. There has been certainty regarding the truthful benefit of surgical resection for patients with PA. Gross total resection (GTR) of PAs, especially those being situated in deep regions, remains a surgical challenge. Generally, they are considered as benign and usually develop in young patients. PAs, belonging to WHO I can be cured by radical resection. The patients with PA have excellent prognosis if complete resection can be conducted...

The blood-brain barrier is a dynamic and highly organized structure that strictly regulates the molecules allowed to cross the brain vasculature into the central nervous system. The blood-brain barrier pathology has been associated with a number of central nervous system diseases, including vascular malformations, stroke/vascular dementia, Alzheimer's disease, multiple sclerosis, and various neurological tumors including glioblastoma multiforme. There is a compelling need for representative models of this critical interface...

Tinnitus is a phantom sound that can be a symptom of various disorders such as hearing loss, cardiovascular diseases, neurological disorders, diabetes or tumors. Because of the inability to divert the auditory attention from tinnitus sound, patients suffer with insomnia, problems with concentration and other psychological conditions, in some extreme cases including major depression symptoms. The auditory character of tinnitus induces the patients to seek help predominantly at the otolaryngologist practice. The first aim of a physician is to establish the cause of tinnitus and to measure its audiological properties...
