Local recurrence of rectal cancer was identified in 31 patients and established in 30 during operation, endoscopy and pathological examination. No local recurrence was found in 5 patients without specific accumulation of 99mTc during the follow-up. Immunoscintigraphy had a positive rate of 86.11%, a specificity of 83.33%, and a sensitivity of 100%.CONCLUSION: Immunoscintigraphy has a highly specific and predictive value for detecting local recurrent rectal cancer, especially after abdominal perineal resection (APR).展开更多

Case: patient female, with AML-M2, hospitalized with fever, dyspnea, nausea, myasthenia, abdominal pain and diarrhea. In the physical examination exacerbated lesion in abdominal wall and subcutaneous nodules in upper and lower limbs. The computed tomography of the chest evinced area of attenuation in ground-glass opacities in the middle lobe, tending to consolidation and bilateral nodular opacities with ground-glass halo which suggested an infiammatory/infectious process of fungal etiology. Immunoscintigraphy with ^99mTc-besilesomab (Scintimun) identified focal infectious processes in activity, scattered over cutaneous and subcutaneous tissues, predominantly in extremities. In blood culture test, there was a growth ofFusarium sp. There is a difficulty in the diagnosis of fungal infections, both in clinical and imaging methods. There is no specific method to reaching the target. In addition, fungal diseases can be divided into focally localized or disseminated infections. There is a greater difficulty in the diagnosis of immunocompromised individuals due to the deficiency of basic defense mechanisms. Scintimun (scintigraphy with besilesomab) is a useful tool of nuclear medicine in the diagnosis of infectious and inflammatory diseases to allow the image of the whole-body and in vivo detection of early pathological and physiological phenomena, even before anatomical alterations occur.展开更多
