ABSTRACT
PURPOSE: To evaluate and demonstrate the MRI findings of renal transplant recipients with hip and knee pain and to investigate the most common etiology of pain. MATERIALS AND METHODS: 69 hip MRIs of 57 patients with hip pain and 30 knee MRIs of 24 patients with knee pain with no history of trauma were retrospectively evaluated by two radiologists. RESULTS: In the evaluation of hip MRIs, 24 patients had avascular necrosis and effusion, 2 patients had bone marrow edema consistent with early stage of avascular necrosis. 18 patients had only intraarticular effusion, 6 patients had tendinitis, 6 patients had bursitis and 1 patient had soft tissue abscess. Five patients had muscle edema and five patients had muscle atrophy as additional findings to the primary pathologies. Among patients with knee pain, nine patients had degenerative joint disease. Seven patients had chondromalacia, five had bone marrow edema, six had meniscal tear, six had ligament rupture and two had bone infarct. Three of the patients had muscle edema accompanying to other pathologies. CONCLUSION: The most common etiology of hip pain in renal transplant recipients is avascular necrosis as expected, intraarticular effusion is found to be the second reason for pain. However, knee pain is explained by ligament pathology, meniscal tear, chondromalacia or degenerative joint disease rather than osteonecrosis.

Acute cerebellitis (AC) is an inflammatory process involving the cerebellum. Usually, this pathology is bilateral; it is unusual to have a unilateral cerebellitis. Only seven cases of hemicerebellitis have been reported in the literature. Here, we review the literature and report the magnetic resonance imaging (MRI) and proton-magnetic resonance spectroscopic (+H-MRS) findings of a case of acute hemicerebellitis in a 15-year-old girl presenting with 15 days' history of headache.
