ABSTRACT
We report two cases of patients complaining of lumbar back pain of unknown etiology which were finally diagnosed as multiple myeloma. The first case was a woman in her 80s with a chief complaint of lumbar back pain. The second case was a male in his 70s. He also consulted our institution because his pain did not subside despite receiving increased doses of oral medication and nerve blocks from his previous doctor. Both patients presented with compression fractures on plain radiography, and additionally with cytopenia, hyperproteinemia, and hypoalbuminemia in blood tests. Further tests were conducted due to suspected multiple myeloma, revealing a punched-out legion in the skull and elevated levels of ß2 microglobulin and Immunoglobulin G. Subsequently, both patients were transferred to the hematology department. In these two cases, we had predicted the presence of multiple myeloma from the results of initial testing and subsequently successfully provided definitive diagnoses following additional examinations.
ABSTRACT
Transesophageal echocardiography (TEE) is a necessary diagnostic tool for cardiac surgery, including for intraoperative evaluation of the morphology and function of each structure. On the other hand, many complications caused by insertion and manipulation of the TEE probe have been reported, such as gastrointestinal injuries and hematoma, as well as esophageal perforation. Here, we report a case in which a large submucosal esophageal hematoma was found on the fourth postoperative day after surgery using TEE for mitral regurgitation. The patient was an 81-year-old man who underwent mitral valve replacement for mitral regurgitation. On the fourth postoperative day, anorexia and blood-tinged sputum were observed. A computed tomography (CT) scan of the chest displayed a giant esophageal submucosal hematoma. When performing TEE, to avoid complications, it is important to handle the TEE probe with care and to avoid leaving the device at the same site for long periods of time.
