Glenohumeral Joint Sepsis after Joint Injection through a New Tattoo by Richard Becker et al. |
Published: 2017 Nov
Issue: 11(11) :: Pages: 28-35
| Abstract: We report a case of Propionibacterium acnes septic arthritis of a shoulder following two joint access procedures. Methodical investigation of these two procedures was performed using the Joint Commission root cause analysis matrix, which involved examination of protocols, interviews with technologists and physicians, and inspection of the procedure rooms and equipment. No procedural error or other causal factor for infection was found other than the injection through a five day-old tattoo during the first procedure. We could find no other reported cases of Propionibacterium acnes seeding a joint via an arthrogram needle. This may be an under-reported phenomenon or could be a unique case. In either instance, the occurrence bears notice by anyone performing joint access procedures.

Multimodal Imaging for the Assessment of a Cardiac Mass - A Case of Primary Cardiac Sarcoma by Benjamin Abels et al. |
Published: 2017 Nov
Issue: 11(11) :: Pages: 11-19
| Abstract: We present a case of an 85-year-old patient who underwent clinical work-up for chronic heart failure, acute coronary syndrome, and pulmonary embolism, until she was diagnosed with a cardiac mass that was histologically identified as sarcoma. The aim of this educational case report is to raise awareness of cardiac masses and to point out diagnostic hints towards a cardiac tumor on chest X-ray, coronary angiography, echocardiography, and chest CT. Moreover, the vital role of cardiac magnetic resonance for the diagnosis of a cardiac mass is highlighted.

Renal myxoma in a pediatric transplant recipient by Jeffrey J Tutman et al. |
Published: 2017 Nov
Issue: 11(11) :: Pages: 20-27
| Abstract: Renal myxoma is a very rare benign neoplasm seen almost exclusively in adults with only 16 reported cases in the literature. All of these cases have been reported in native kidneys with none being reported in a transplant kidney. We report the case of a renal myxoma in a 17-year-old boy’s transplant kidney that was found as an incidental mass on ultrasonography and further evaluated with CT and PET scans. PET findings of a renal myxoma are reported here for the first time, and imaging findings from previous cases are briefly reviewed. This case report highlights the fact that adult-predominant tumors and pathology should always be a consideration in pediatric patients who receive organ transplants from adult donors.

Skull base and craniocervical bone pneumatisation: two case reports of differing presentations and a review of the literature by Olivia Francies et al. |
Published: 2017 Nov
Issue: 11(11) :: Pages: 1-10
| Abstract: We report two patients with increased central skull base and craniocervical junction bone pneumatisation complicated by extra-osseous gas. One patient presented with symptoms of increasing nasal blockage and `sinus pressure` on a background of extensive nasal polyposis. He was subsequently found to have a history of repeated Valsalva`s manoeuvre, the cessation of which resulted in a rapid decrease in the amount of extra-osseous gas on imaging. The second patient presented following a minor head trauma with dysarthria from a hypoglossal nerve palsy and neck pain, with extensive intra- and extra-cranial gas including within the spinal canal (pneumorrhachis). These radiological findings have been reported previously in patients with Eustachian tube dysfunction and/or activities leading to frequently raised middle ear pressures. We review the possible aetiologies, reported risk factors, and the range of associated imaging abnormalities that may be encountered with this rare appearance.
