[Primary tubulointerstitial nephritis is characterised by an inflammatory infiltrate of tubulointerstitial space. The infiltrate consists of T and B lymphocytes, monocytes, macrophages, neutrophyl and eosinophyl granulocytes in varying degree. It is associated with interstitial oedema and different level of tubular damage. The disease exists in acute and chronic form. The main causes of this condition are: drugs, infection, systemic diseases, malignancy and in some cases the disease is idiopathic. The pathogenesis in most cases is immune-mediated. The secondary form of tubulointerstitial nephritis can occur in primary glomerular and vascular disease and is characterised by tubulointerstitial fibrosis and tubulus atrophy. The morphological alterations are major determinants of the progression of chronic renal disease. In both forms of tubulointerstitial nephritis the development of renal insufficiency is often observed.]

[The diseases of connective tissue and musculoskeletal system frequently associated with typical eye disorders. These can either be mild, recovering fully after treatment or more serious with persisting symptoms and destructive changes resulting in permanent loss of sight Eye symptoms can occur in the following diseases: rheumatoid arthritis, juvenile chronic arthritis, neonatal onset multisystem disease, ankylosing spondylitis, seronegative spondarthrities, Reiter’s syndrome, Behçet’s syndrome, Lyme disease, systemic lupus erythematosus, scleroderma, polyarteritis nodosa, Wegener’s granulomatosis, giant cell arteritis, erythema nodosum, relapsing polychondritis, sarcoidosis, Marfan’s syndrome, osteogenesis imperfecta.]

[The diagnosis of giant-cell arteritis is a real challenge for clinicians. There are several reasons for the difficulties in establishing the diagnosis. This disease is associated to rare conditions, therefore most physicians lack clinical experience. This condition shows very heterogeneous manifestation, the intensity of the symptoms vary in time. Early diagnosis is of great importance in order to prevent ischemic complications. Among these complications one should emphasise the role of anterior ischemic optic neuropathy that may result in abrupt blindness. In this case report, we show a rare socalled large vessel manifestation of giant-cell arteritis. This form of the disease needs different approach in diagnosis where color duplex ultrasonography may have distinguished importance. The final verification of the diagnosis is based on histology. However the lack of all histological criteria do not exclude the presence of giant-cell arteritis.]
