Shear-Wave Elastography of Segmental Infarction of the Testis
Fatih Kantarci,Deniz Cebi Olgun,Ismail Mihmanli 대한영상의학회 2012 Korean Journal of Radiology Vol.13 No.6
Segmental testicular infarction (STI) is a rare cause of acute scrotum. The spectrum of findings on gray-scale and color Doppler ultrasonography differ depending on the time between the onset of testicular pain and the ultrasonography examination. We are not aware of the usefulness of shear-wave elastography for the diagnosis of STI. We report the shear-wave elastography features in a case of STI and discuss the role of this diagnostic modality in the differential diagnosis.

Neurofibromatosis type 1 disease is characterized by pigmented cutaneous lesions and generalized tumors of a neural crest origin and it may affect all the systems of the human body. Sphenoid dysplasia is one of the characteristics of this syndrome and it occurs in 5-10% of the cases; further, abnormalities of the sphenoid wings are often considered pathognomonic. However, complete agenesis of a sphenoid wing is very rare. We report here on an unusual case of neurofibromatosis type 1 disease with the associated absence of a sphenoid wing that was diagnosed by using multidetector computed tomography.

A patient with a 2-year history of pain in the left arm, and decreased strengths unrelieved by non-steroidal antiinflammatory therapy, was being referred for repeating radiography. The radiologic examinations have demonstrated a unique pattern of non-contiguous osteolysis in the left elbow, proximal and distal radius, ulna, wrist, carpal bones, proximal and distal metacarpals and phalanges. Multi-site biopsies were being performed and confirmed the diagnosis of massive osteolysis. To our knowledge, this is the first case in which multifocal, non-contiguous osteolysis with skip lesions without associated nephropathy and without a hereditary pattern is being described in one extremity.
Giant Multilocular Cystadenoma of the Prostate: A Rare Cause of Huge Cystic Pelvic Mass
Deniz Cebi Olgun,Bulent Onal,Ismail Mihmanli,Fatih Kantarci,Haydar Durak,Hale Demir,Bulent Cetinel1 대한비뇨의학회 2012 Investigative and Clinical Urology Vol.53 No.3
Giant multilocular prostatic cystadenoma is a rare benign tumor that evolves from the prostate gland. Obstructive voiding symptoms occur in all reported cases. These lesions do not invade adjacent structures. Preoperative radiologic evaluation can define the benign nature of the lesion. Here we report a case of large cystic lesions identified by magnetic resonance imaging and sonographic findings that caused an extensive mass effect in the pelvis. When retrovesical, huge cystic lesions fill the pelvis completely in young men, with high levels of serum prostate-specific antigen, giant multilocular prostatic cystadenoma should be considered as a differential diagnosis. To our knowledge, this is the youngest case of prostatic cystadenoma reported in the literature.

Background: To assess the long term clinical outcome of preoperative radiotherapy with or without chemotherapy followed by limb sparing surgery in patients with non-metastatic soft tissue sarcomas (STS) of the extremities. Materials and Methods: Sixty patients with locally advanced STS were retrospectively analyzed. The median tumor diameter was 12 cm. All patients were treated with preoperative radiotherapy delivered with two different fractionation schedules (35Gy/10fr or 46-50Gy/23-25fr). Neoadjuvant chemotherapy was added to 44 patients with large and/or high grade tumors. Surgery was performed 2-6 weeks after radiotherapy. Chemotherapy was completed up to 6 courses after surgery in patients who had good responses. Results: Median follow-up time was 67 months (8-268 months). All of the patients had limb sparing surgery. The 5-year local control (LC), disease free (DFS) and overall survival (OSS) rates for all of the patients were 81%, 48.1% and 68.3% respectively. 5-year LC, DFS and cause specific survival (CSS) were 81.7%, 47%, 69.8%, and 80%, 60%, 60% in the chemoradiotherapy and radiotherapy groups, respectively. On univariate analysis, patients who were treated with hypofractionation experienced significantly superior LC, DFS and CSS rates with similar rates of late toxicity when compared with patients who were treated with conventional fractionation and statistical significance was retained on multivariate analysis. Conclusions: Treatment results are consistent with the literature. As neoadjuvant chemoradiotherapy provides effective LC and CSS with acceptable morbidity, it should be preferred for patients with large and borderline resectable STS.
