[Successful Early Surgical Treatment for Infected Traumatic Pulmonary Pseudocyst].

Almost all traumatic pulmonary pseudocysts (TPP), such as cavitary pulmonary lesions after blunt chest trauma, resolve spontaneously. On the contrary, secondary infection of a TPP should be considered in the presence of purulent sputum or hemosputum and a persistent cavity. We report a case of an infected TPP that was successfully treated by early surgical treatment. A 25-year-old man was transferred to our hospital with a TPP, shown by computed tomography (CT) as having a thick-walled large cavity, after the acute phase of blunt chest trauma. Purulent hemosputum suggested infection of the cavity. Serial CT scans of the chest revealed a persistent cavity. The thick-walled large cavity was diagnosed as a secondary infection of the TPP, that is, a potential lung abscess. We resected the cavity before a systemic inflammatory reaction occurred.

[CLINICAL INVESTIGATION OF 6 CASES OF TUBERCULOUS SPONDYLITIS].

[Objective] A delay in the diagnosis of tubercu- lous spondylitis can result in worsening of the condition. We investigated previously reported cases of tuberculous spondylitis, as well as cases experienced in our hospital, to identify factors that are useful in the diagnosis. [Materials and Methods] We retrospectively evaluated six cases of tuberculous spondylitis diagnosed in our hospital between October 2007 and September 2012, and an additional 23 cases that had been reported in Japan between 1994 and 2014. [Results] The median age of our six patients was 78.5 years and five were women. In all cases, the focal lesion was seen in 2-3 adjacent vertebrae; four patients had miliary tuberculosis and five had lower back pain. All patients received oral treatment for 10-12 months. Among the 23 patients previously reported, 57% were women, and a focal lesion was found in 2-3 adjacent vertebrae in 86%. In addition, 57% had miliary tuberculosis and 65% had lower back pain. A personal and family history of tuberculosis was found in 20% and 26%. [Discussion] Radiographic assessment and microbiological testing of areas other than the chest and spine are useful in the diagnosis of tuberculous spondylitis. Furthermore, lower back pain, lower extremity symptoms, and personal and family history of tuberculosis are important factors. [Conclusion] When tuberculous spondylitis is suspected, diagnosis may be possible by investigating focal lesions in areas other than the spine.
