INTRODUCTION: Endoscopic endonasal transsphenoidal surgery (EETS) is increasingly applied to treat tuberculum sellae meningiomas. However, if the tumor adheres firmly to the optic nerve, dissection of the interface between both structures should be prudent to preserve visual function. The purpose of this study was to investigate whether tumor adhesion to the optic nerve can be predicted preoperatively by fast imaging with steady-state acquisition (FIESTA). METHODS: Twenty-two patients with tuberculum sellae meningioma treated with EETS were retrospectively identified...

OBJECTIVE In tuberculum sellae meningioma (TSM) surgery, endonasal approaches are claimed to have a superior visual outcome compared with transcranial approaches. The authors question whether this is always true and analyze their series of cases of endoscope-assisted transcranial TSM surgery with special regard to the postoperative visual outcome in order to explore this issue. METHODS All surgical procedures for TSM performed between 2003 and 2015 in the Department of Neurosurgery, University Medicine Greifswald, were retrospectively analyzed...

OBJECTIVE: The objective of this article is to summarize the physical principles, technology features, and first clinical applications of optical imaging techniques to the breast. CONCLUSION: Light-breast tissue interaction is expressed as absorption and scattering coefficients, allowing image reconstruction based on endogenous or exogenous contrast. Diffuse optical spectroscopy and imaging, fluorescence molecular tomography, photoacoustic imaging, and multiparametric infrared imaging show potential for clinical application, especially for lesion characterization, estimation of cancer probability, and monitoring the effect of neoadjuvant therapy...

BACKGROUND AND IMPORTANCE: Myxoid liposarcoma is not an uncommon form of sarcoma. However, it usually affects the lower extremity long bones. Scapular involvement is extremely rare, as is a metastasis to the parasellar region. We present a case of liposarcoma of the skull base originating in the scapular region and metastasizing to the sellar and parasellar regions and provide a review of the pertinent literature. CLINICAL PRESENTATION: A 43-year-old female patient diagnosed with left scapular myxoid liposarcoma was treated with surgical resection...

BACKGROUND AND IMPORTANCE: Collision tumors are the simultaneous occurrence of more than one type of neoplasm within an anatomic space. In the pituitary sella, collision tumors are exceedingly rare, and not much is known about their etiology and prognosis. CLINICAL PRESENTATION: A 74-year-old man presented with a concomitant primary pituitary lymphoma (diffuse large B-cell non-Hodgkin's lymphoma; DLBCL) and follicle-stimulating hormone (FSH)-adenoma diagnosed histologically after clinical features of apoplexy prompted urgent surgical decompression and resection...

Sphenoid bone may be affected by different variants of pneumatisation, which have a relevant importance from a clinical and surgical point of view. The description of such variants in different populations may give useful information. However, few articles describe the variability of sphenoid pneumatised structures and none of them focuses on Northern Italian population. Variants of pneumatisation of sphenoid bone were described in a sample of 300 Northern Italian patients who underwent a CT scan. More than fifty-seven percent of patients showed a form of anatomical variant: the most common form was the pneumatised pterygoid processes (39...

Cushing's syndrome (CS) can be classified as adrenocorticotropic hormone (ACTH)-dependent or ACTH-independent depending on the ACTH levels. However, 30% of the patients with CS have ACTH levels in the 'grey zone' (5-20 pg/mL), thereby posing a challenge in establishing the aetiological diagnosis. In a patient with full-blown features of Cushing's syndrome with equivocal ACTH levels, and a pituitary microadenoma on contrast-enhanced MRI sella, can falsely lead to a diagnosis of Cushing's disease. Pituitary microadenoma, if <6 mm in size, may be an incidental finding (incidentaloma) in this scenario and can be present in ∼3-27% of the healthy population...

BACKGROUND: The range of vertebrate hosts on which species of mosquito blood-feed is an important parameter for identifying potential vectors and in assessing the risk of incursion and establishment of vector-borne pathogens. In the United Kingdom, studies of mosquito host range have collected relatively few specimens and used techniques that could only broadly identify host species. This study conducted intensive collection and analysis of mosquitoes from a grazing marsh environment in southeast England...
