Involvement of the brain and meninges is rare in cases of Wegener granulomatosis, occurring in 2% to 8% of cases. Meningeal involvement in association with Wegener granulomatosis has scarcely been reported as being confined to the dura mater of brain on images and is thought to represent granulomatous infiltration. There are a few reported cases of Wegener granulomatosis that document involveme...

Orofacial granulomatosis (OFG) is a granulomatous disease of the orofacial region which appears usually as a persistent and/or recurrent labial soft tissue swelling in the orofacial region and is characterized histologically by a granulomatous inflammation. OFG may cause significant cosmetic and functional problems but can be prevented if the disease is diagnosed early and promptly treated. Thi...

Wegener's granulomatosis of the pituitary gland resulting in diabetes insipidus is a rare complication of the disease. Standard treatment for Wegener's granulomatosis involves a combination of prednisolone and cylophosphamide, however biologic agents are now being used in refractory cases. We report three cases of patients with diabetes insipidus as a complication of Wegener's granulomatosis wh...

Granulomatosis with polyangiitis (GPA, formerly known as Wegener's Granulomatosis) is an autoimmune small vessel vasculitis which is highly associated with anti-neutrophil cytoplasmic antibodies (ANCA). The hallmarks of this condition are systemic necrotising vasculitis, necrotising granulomatous inflammation, and necrotising glomerulonephritis. The aetiology of granulomatosis with polyangiitis...

Wegener's granulomatosis or granulomatosis with polyangiitis is a necrotizing vasculitis affecting both arterioles and venules. The disease is characterized by the classical triad involving acute inflammation of the upper and lower respiratory tracts with renal involvement. However, the disease pathology can affect any organ system. This case presents Wegener's granulomatosis presenting with fa...

We prove a Wegner estimate for generalized alloy type models at negative energies (Theorems 8 and 13). The single site potential is assumed to be non-positive. The random potential does not need to be stationary with respect to translations from a lattice. Actually, the set of points to which the individual single site potentials are attached, needs only to satisfy a certain density condition. ...

An injective coloring of graphs is a vertex coloring where two vertices receive distinct colors if they have a common neighbor. In 1977, Wegner [12] posed a conjecture on the chromatic number of squares of graphs which remains unsolved for planar graphs with maximum degrees ∆ ≥ 4. Obviously, the chromatic number of the square of a graph is at least the injective chromatic number of a graph. We ...

Granulomatous lung diseases are a heterogeneous group of disorders that have a wide spectrum of pathologies with variable clinical manifestations and outcomes. Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of granulomat...

Lymphomatoid granulomatosis is an uncommon disorder that can present as multiple pulmonary nodules. Systemic manifestations such as fever, weight loss, skin lesions, and other organ involvement may occur. The clinical presentation of lymphomatoid granulomatosis can mimic infectious diseases (eg, tuberculosis), vasculitis, or metastatic malignancies.1 Lymphomatoid granulomatosis should be consid...
