Atypical findings of discordant bone scan and radiographs in transient osteoporosis of the hip: case report and review of the literature.
The authors report atypical findings of discordant bone scans and radiography seen in a patient with transient osteoporosis of the hip (TOH). Presented in the case of a 60-year-old man who had spontaneous onset of left hip pain which worsened for 2 months with weight-bearing on the affected side. Initial and follow-up radiographs of the let hip were normal. Bone scan demonstrated intense uptake of Tc-99m MDP in the affected femoral head and neck, corresponding to characteristics of abnormal signal intensity of TOH or transient bone marrow edema syndrome on MRI. This discordant pattern of bone scan and radiographs has rarely been reported in the literature. Its possible mechanism of causation and clinical implication in TOH, together with a review of the literature, are discussed in this report.
