      Abstract: Background Renal angiomyolipoma is rare, but many of these patients may have an acute debut with severe bleeding. These patients need urgent treatment with interventional embolization as an attractive option. Purpose To investigate the technical and clinical effect of this treatment and to evaluate long-term clinical outcomes with clinical control and radiological imaging. Material and Methods Eight patients with angiomyolipoma were treated with embolization. Five patients were treated acutely. Five patients were followed-up for mean 4.5 years with clinical and radiological examinations. Results The renal angiomyolipoma decreased significantly from mean 7.2 cm to 2.9 cm after embolization (p = 0.04). Cortical infarctions of about one-third of the circumference of the embolized kidneys could be detected on follow-up examinations, but all patients had normal total kidney function. The bleeding was primarily stopped in all patients, however, in one patient bleeding from a lumbar artery was supplementary embolized within 24 h. In another case the interventional procedure ended up in embolization of the whole kidney as it was impossible to embolize all the feeding arteries selectively. One patient had a nephrectomy one month after embolization because of infection and re-bleeding and one patient after 2.5 years because of tumor size >4 cm. The technical success was 7/8 (88%) and clinical success was 6/8 patients (75%). Conclusion Selective embolization of renal angiomyolipoma is a minimally invasive and safe procedure with few complications. It is a nephron sparing alternative to renal resection. The reduction in tumor size after embolization is significant and long-lasting.

  • Transformation of benign fibroadenoma to malignant phyllodes tumor

    • Authors: Sanders, L. M; Daigle, M. E, Tortora, M, Panasiti, R.
      Pages: 2058460115 - 2058460115
      Abstract: The transformation of a benign fibroadenoma into a phyllodes tumor is uncommon and unpredictable. We report the case of a 40-year-old woman with a core biopsy proven fibroadenoma that underwent transformation into a malignant phyllodes tumor after 3 years of size stability. We present ultrasound and magnetic resonance images, as well as pathology slides from core biopsy and surgical excision, to illustrate this transformation. It has been suggested that phyllodes tumors may be misdiagnosed as fibroadenomas by core biopsy. However, in this case, pathology supports correct initial diagnosis of fibroadenoma and demonstrates a portion of the original fibroadenoma along the periphery of the malignant phyllodes tumor.

  • Radiofrequency ablation of unresectable colorectal liver metastases:
           trends in management and outcome during a decade at a single center

      Abstract: Background Radiofrequency ablation (RFA) is widely used for treatment of colorectal liver metastases (CRLM). Purpose To evaluate the effect of increased experience in RFA of CRLM on morbidity and survival, and the trends in patient management and outcomes during the last decade. Material and Methods Hospital records of the initial 52 consecutive patients who underwent RFA (56 procedures/70 lesions) were retrospectively reviewed. The patients were divided into two groups according to time period of treatment, period I (2001–2006: n = 26) and period II (2007–2011: n = 26). Results Concomitant liver resection was performed in 15 patients in each period. Operative morbidity decreased from 47% to 19% (P = 0.047). Most complications were found in patients who underwent a concomitant liver resection and not related to the ablation per se. Local recurrence rate decreased from 19.4% to 12.9% (P = 0.526). At least one risk factor for recurrence was found in patients with local recurrence (n = 11): subcapsular localization (n = 4), tumor size >3 cm and subcapsular localization (n = 2), and perivascular localization (portal veins/hepatic veins) (n = 5). Median overall survival was 32 months in period I and 49 months in period II, whereas estimated 5-year survival was 19% and 36%, respectively (P = 0.09). Adjuvant chemotherapy was given to four patients (15.4%) in period I and 13 patients (50%) in period II (P = 0.017). Conclusion RFA alone or in combination with liver resection is a potentially curative treatment to selected patients with CRLM. Over time, the morbidity and survival have improved in RFA of CRLM. Although a possible effect of a learning curve should be taken into consideration in the appraisal of this improvement, it is more likely to be attributable to optimization of indication, development in surgical techniques, and increased use of perioperative chemotherapy.

  • Radiographic development during three decades in a patient with psoriatic
           arthritis mutilans

    • Authors: Laasonen, L; Gudbjornsson, B, Ejstrup, L, Iversen, L, Ternowitz, T, Stahle, M, Lindqvist, U.

      Abstract: Psoriatic arthritis mutilans (PAM) is the most severe and rare form of psoriatic arthritis (PsA). We describe radiological development in a typical case of PAM covering three decades in order to elucidate the need for early diagnosis of PAM. Radiographs of hands and feet, taken from 1981 to 2010, were evaluated using the Psoriatic Arthritis Ratingen Score (PARS). When PsA was diagnosed, in 1981, gross deformity was observed in the second PIP joint of the left foot. Several pencil-in-cup deformities and gross osteolysis were present in the feet in the first decade of the disease. Over 10 years, many joints had reached maximum scores. During the follow-up, other joints became involved and the disease developed clinically. Reporting early signs suggestive of PAM, e.g. pencil-in cup deformities and gross osteolysis in any joint, should be mandatory and crucial. This would heighten our awareness of PAM, accelerate the diagnosis, and lead to improved effective treatment in order to minimize joint damages resulting in PAM.

  • Malignant ascites in patients with terminal cancer is effectively treated
           with permanent peritoneal catheter

    • Authors: Meier, M; Mortensen, F. V, Madsen, H. H. T.
      Pages: 2058460115 - 2058460115
      Abstract: Background Malignant ascites is a pathological condition caused by intra- or extra-abdominal disseminated cancer. The object of treatment is palliation. In search of an effective and minimally invasive palliative treatment of malignant ascites placement of a permanent intra peritoneal catheter has been suggested. Purpose To evaluate our experiences with treatment of malignant ascites by implantation of a permanent PleurX catheter. Material and Methods A retrospective study was conducted, comprising 20 consecutive patients with terminal cancer, who had a permanent PleurX catheter implanted because of malignant ascites in the period from February to November 2014. Using the patients’ medical records, we retrieved data on patients and procedures. Results The technical success rate was 100%. Catheter patency was 95.2%, one catheter was removed due to dislocation. Ten patients (50.0%) experienced minor adverse events. No procedural difficulties were reported and there was no need for additional treatment of malignant ascites after catheter implantation. Median residual survival after catheter implantation was 27 days. Conclusion Implantation of a permanent PleurX catheter is a minimally invasive and effective procedure with only minor adverse events and a high rate of catheter patency in patients with malignant ascites caused by terminal cancer disease.
