Lymphomatoid granulomatosis is an uncommon disease characterized by a perivascular pleomorphic cellular infiltration and necrosis. CNS involvement occurs in 20% of the cases. CT findings have been described in five of the previously reported cases of CNS lymphomatoid granulomatosis, and include unifocal, multifocal, and diffuse contrast-enhancing supratentorial lesions. We reviewed the CT scans...

Wagener's granulomatosis (WG) is a rheumatologic disease with unknown etiology which renal and pulmonary involvement is commonly seen. Renal involvement in Wagener's granulomatosis represents as a segmental necrotizing glomerulonephritis which is not visible with imaging techniques and usually presents with proteinuria, microhematuria, and hypertension. A rare presentation of the disease is a r...

We consider scalar field theories in dimensions lower than four in the context of the Wegner-Houghton renormalization group equations (WHRG). The renormalized trajectory makes a non-perturbative interpolation between the ultraviolet and the infrared scaling regimes. Strong indication is found that in two dimensions and below the models with polynomial interaction are always non-perturbative in ...

We report a case of bilateral acute angle-closure glaucoma in a patient with undiagnosed granulomatosis with polyangiitis (Wegener's). A 59-year-old man presented with a severe headache, ocular pain, blurred vision, shortness of breath, and mild fever. Clinical examination revealed conjunctival chemosis, corneal edema, and shallow anterior chambers. Closed angles were observed bilaterally on go...

Three cases of Wegener's granulomatosis with cardiac complications are described and the relevant published reports are reviewed. The first case of Wegener's granulomatosis was associated with aortic regurgitation and required aortic valve replacement. The second and third cases were associated with pericardial disease requiring pericardiectomy for constructive pericarditis in one case, and hae...

Wegener's granulomatosis, also known as anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, is a small vessel vasculitis with primarily pulmonary, renal, and sinus disease manifestations. The prevalence of Wegener's granulomatosis is three cases per 100,000 patients. Cardiovascular, neurologic, cutaneous, and joint manifestations have been reported in many case reports and case s...

Pulmonary Langerhans cell granulomatosis is defined as an abnormal Langerhans cells infiltration in the lungs. Multifocal involvement is unusual, however. We report 3 cases of pulmonary Langerhans cell granulomatosis combined with either rib, thyroid or hypothalamus involvement.

BACKGROUND Orbital involvement in Wegener's Granulomatosis (WG) is rare and has an overall good prognosis. CASE A 60-year-old hypertensive Indian female presented with vision loss and painful proptosis of left eye. Orbital incisional biopsy suggested necrotising small vessel inflammation. The saddle nose deformity and pedal nodulo- ulcerative lesions further consolidated the diagnosis of Wege...
