Case ReportsHybrid SPECT-CT with 99mTc-labeled red blood cell in a case of blue rubber bleb nevus syndrome: added value over planar scintigraphy.
Blue rubber bleb nevus syndrome (BRBNS) is a rare clinical entity characterized by multiple venous malformations (hemangiomas) of the skin and gastrointestinal tract. These hemangiomas usually cause episodes of occult gastrointestinal bleeding leading to iron deficiency anemia, and also carry a significant potential for serious hemorrhage. The 99mechnetium (99mTc)-labeled red blood cell scintigraphy has traditionally been utilized in the localization of occult bleeding sites in patients with suspected vascular malformations, angiodysplasia, and Meckel’s diverticulum. We report the incremental value of 99mTc-labeled red blood cell hybrid single-photon emission computed tomography-computed tomography (SPECT-CT) over planar scintigraphy alone in a 12-year-old female patient with BRBNS.

Comparative StudyHybrid SPECT-CT for characterizing isolated vertebral lesions observed by bone scintigraphy: comparison with planar scintigraphy, SPECT, and CT.
We aimed to assess the role of single photon emission computed tomography-computed tomography (SPECT-CT) for characterizing isolated vertebral lesions observed by bone scintigraphy compared to planar scintigraphy, SPECT, and CT, and to evaluate the impact of SPECT-CT on patient management. ⋯ SPECT-CT is better than planar scintigraphy and SPECT alone, but not CT alone, for characterizing equivocal vertebral lesions that are observed by bone scintigraphy, thus SPECT-CT can have a significant impact on patient management.

Case ReportsSecondary aortoesophageal fistula after thoracic endovascular aortic repair for a huge aneurysm.
Thoracic endovascular aortic repair for a descending thoracic aortic aneurysm is an excellent alternative to open surgery, especially in patients with a number of comorbidities. It may cause fatal complications, including aortoesophageal fistula, but these are very rare. Here, we report the case of secondary aortoesophageal fistula four months after the procedure for a huge descending thoracic aortic aneurysm, which presented with new-onset high-grade fever accompanied by elevated inflammatory markers.
