Muscle Attenuation

Limited studies have investigated the correlation between body composition and prostate cancer outcomes. We analyzed the effect of muscle mass and quality on castration-resistant prostate cancer (CRPC) outcomes. Skeletal muscle index (SMI) and skeletal muscle attenuation (SMA) were measured for 411 patients at the L3 vertebral level using computed tomography at CRPC diagnosis and were dived to low and high groups at the value of median. Analysis of the skeletal phenotypes and age (<70 and >70 years) was performed to evaluate the effect of SMI and SMA. The median survival rates for patients with low and high SMI were 19 and 24 months (p = 0.015), and those with low and high SMAs were 15 and 26 months (p < 0.001), respectively. In the subgroup analysis by age, SMA was a significant prognosticator in both groups, while SMI was a significant prognosticator only in patients aged >70 years. Patients with low SMA + low SMI had the worst prognosis. Muscle characteristics seems to be a prognosticator in survival of CRPC patients and may be considered in treatment planning.

Coronary Artery Fistulas

Coronary artery fistulas, including coronary pulmonary fistulas, are usually discovered accidently among the adult population when undergoing invasive coronary angiographies. We report here a 58-year-old woman with dual fistulas originating from the left anterior descending coronary artery and right coronary sinus to the main pulmonary artery, demonstrating noninvasively with multidetector-computed tomography (MDCT) and transthoracic echocardiography (TTE).

Objective.Because zygapophyseal joints (ZJ) are difficult to visualize on radiographs, little is known about the relationship of ZJ fusion to other features of spinal damage in ankylosing spondylitis (AS). We used computed tomography (CT) to investigate the concordance of ZJ fusion and syndesmophytes, and examined the contribution of both features to spinal motion.Methods.We performed thoracolumbar CT scans (T10–T11 to L3–L4) on 55 patients. Two readers scored scans for ZJ fusion, which were compared to syndesmophyte height and extent of bridging, measured by computer algorithm at the same levels. We used multiple regression analysis to evaluate the relative contributions of ZJ fusion and syndesmophytes to spinal mobility.Results.Fifty-one percent of patients had ZJ fusion in at least 1 vertebral level. Fusion was present in 129 of 652 individual ZJ. Syndesmophytes and bridging were often present in vertebral levels without ZJ fusion, suggesting that syndesmophytes most often develop first. ZJ fusion was present in 34% of vertebral levels with syndesmophytes and 55.9% of levels with bridging, suggesting a closer association with bridging. Syndesmophytes and ZJ fusion had similar associations with the modified Schober test, but syndesmophytes were more strongly associated with limitations in lateral thoracolumbar flexion. ZJ rarely showed new fusion over 4 years.Conclusion.Thoracolumbar ZJ fusion in AS is rarely present at vertebral levels without syndesmophytes. Syndesmophytes, therefore, likely appear before ZJ fusion at a given vertebral level. Both syndesmophytes and ZJ fusion contribute to limited forward lumbar flexion, but syndesmophytes contribute more to limited lateral flexion.

The usefulness of spinal computed tomography (CT) in predicting the presence of epidural tumor was evaluated in cancer patients undergoing CT myelography for suspected epidural tumor. Two hundred ninety two vertebral levels were evaluated in 30 patients. Spinal CT demonstrated cortical disruption surrounding the epidural space from metastatic cancer in 109 vertebrae. Eighty-five (78%) of these vertebral levels had tumor extension into the adjacent epidural space. The incidence of epidural tumor adjacent to vertebrae which had normal spinal CT or metastatic tumor without cortical disruption was 11%. Eighty-six percent of the epidural tumor adjacent to these vertebrae were a result of craniocaudal tumor extension in the epidural space from adjacent vertebral levels with cortical disruption. Twenty-one of 23 patients (91%) with cortical disruption at more than one vertebral level on spinal CT had epidural tumor. Synchronous noncontiguous epidural lesions were observed in 38% of patients with epidural tumor. Spinal CT is an important diagnostic test in determining which patients are at high risk for epidural tumor. Myelography should be performed in all patients with suspected epidural tumor to accurately define the full extent of tumor.
