Central nervous system involvement in Whipple's disease: Report of a rare pathological entity and comparative review of treatment strategies and outcomes.

Whipple's disease, caused by the gram-positive actinomycete , is a rare chronic systemic illness with significant diagnostic and therapeutic challenges, particularly when the CNS is involved. This case report details a 46-year-old man presenting with a constellation of symptoms including fatigue, hypersomnia, weight loss, bifrontal headaches, abdominal pain, treatment-unresponsive diarrhea, and skin hyperpigmentation. Neurological examination revealed oculomasticatory myorhythmia, and imaging studies showed nodular enhancement of the hypothalamus and basal ganglia, along with retroperitoneal lymphadenopathy.

Diagnostic and therapeutic dilemmas of asymptomatic intracranial AVMs: A case report and evidence-based review.

First described by Virchow in the 19th century, intracranial arteriovenous malformations (AVMs) are complex, tangle-shaped vascular lesions with a number of associated neuroparenchymal, hemodynamic, and angio-architectural changes. However, the clinical description of extracranial AVMs dates back to the Ebers Papyrus (c. 1500 BC), with a still unknown definitive underlying etiology thus far.

Endoscopic Transnasal Transmaxillary Approach to Orbital Apex through the Meningo-Orbital Band: A Cadaveric Feasibility Study.

Background: Extradural transcranial release of the meningo-orbital band occupying the lateral part of the superior orbital fissure is used to approach the orbital apex and middle cranial fossa. The authors tested the feasibility of the release of the meningo-orbital band via an endonasal transmaxillary approach.

Materials And Methods: Five injected cadaveric heads were assessed for dimensions of superior orbital fissure by computerized tomography.
