Pneumothorax post CT-guided fine needle aspiration biopsy for lung nodules: our experience in king hussein medical center

To determine the rate of pneumothorax post CT-guided fine needle aspiration biopsy and the contributing factors. This descriptive retrospective study was held at King Hussein Medical Center in the period between April 2012 and March 2014, and included 105 patients who were diagnosed to have lung nodules. All patients had a CT-guided fine needle aspiration biopsy for histological diagnosis. Operator, site and location of the nodule, emphysematous lung condition, and pneumothorax detection by CT-scan and chest X-ray were all reviewed. There were 83 males [79%] and 22 females [21%]. Age ranged from 35 to 77 years [mean 62 +/- 10.2]. Right sided nodules constituted 50.3% of the studied sample, 79.1% of the nodules were located peripherally [83 patients] and 19% had associated emphysematous lung changes, 19 patients [18.1%] had post fine needle aspiration biopsy pneumothorax. Of those, seven patients [36.8%] were detected immediately on CT-scan table, eight patients [42.1%] were detected four hours later on chest X-ray, four patients were missed and 13 patients were treated with chest drain. Eleven patients [57.9%] out of the 19 who had pneumothorax had central lesions while eight [42.1%] had peripheral lesions and only six patients [31.5%] had emphysematous changes. Pneumothorax post CT-guided fine needle aspiration is still a common complication in our center and there was no single factor contributing to it

Radiological and pathological findings in partial nephrectomy for renal masses; experience at King Hussein medical center

The aim of this study is to assess the accuracy of radiologic findings of renal masses by comparing them with the histopathologic diagnoses from our personal experience in partial nephrectomy specimens. We reviewed the histopathological reports of 49 patients who underwent partial nephrectomy in a 10 year duration at Prince Hussein bin Abdullah urology and organ transplant centre. Only 32 patients of 49 harbored renal cell carcinoma in their specimens with a percentage of 65.4%. The remaining 15 patients had benign renal conditions in a percentage of 30.6%. Partial nephrectomy is gold standard for small renal masses, which lead to preserve renal tissue and decrease morbidity and mortality from chronic kidney disease knowing that not all masses proved to be renal cell carcinoma. Despite the fact that renal CT-Scan with IV contrast is considered as the modality of choice for the diagnosis of renal tumors still there is a false positive rate although low but exist
