Most accessory ossicles and sesamoid bones of the ankle and the foot remain asymptomatic; however, they have increasingly been examined in the radiology literature, because they can cause painful syndromes or degenerative changes in response to overuse and trauma. Our aim was to document a detailed investigation on the accessory ossicles and sesamoid bones of Turkish subjects in both the feet according to the sex, frequency and division of the bones, coexistence and bilaterality by radiography. A double-centered study was performed retrospectively to determine the incidence of the accessory ossicles and sesamoid bones in the ankle and foot. Accessory ossicles (21.2%) and sesamoid bones (9.6%) were detected by Radiographs of 984 subjects. The most common accessory ossicles were accessory navicular (11.7%), os peroneum (4.7%), os trigonum (2.3%), os supranaviculare (1.6%), os vesalianum (0.4%), os supratalare (0.2%), os intermetatarseum (0.2%). We observed bipartite hallux sesamoid in 2.7% of radiographs. Interphalangeal sesamoid bone of the hallux was seen in 2% of radiographs. Incidences of metatarsophalangeal sesamoid bones were found as 0.4% in the second digit, 0.2% third digit, 0.1% fourth digit and 4.3% fifth digit. We also identified the coexistencies of two different accessory ossicles as 6%, accessory ossicles and sesamoid bones as 7%, and bipartite sesamoid bones and sesamoid bones as 1.9%. Distribution of the most common accessory ossicles in male and female subjects was similar. We reported the incidence of accessory ossicles and sesamoid bones of the feet in Turkish adult population.
Cryoablation has been used for many years as a surgical ablation technique in the prostate and kidney. However, since the introduction of high-intensity focused ultrasound (HIFU) and robotic surgery for prostate tumours, its popularity in the urologic community has declined. In the early 2000s, innovations in cryoablation technology allowed the use of thinner probes, which were suitable for percutaneous application. As a result, radiologists began using cryoablation, first in the liver, and then in other organs or tissues such as the kidney, lung, breast, pancreas, bone, and soft tissue. In most of these locations, cryoablation has great potential given its inherent advantages, including the use of local anaesthesia, little or no pain during and after the procedure, real-time monitoring of the ablation area on US, CT or MRI, the potential for ablation of large tumours with multiple probes, and the ability to change the shape of the ablation in non-spherical tumours. Yet despite these advantages, the use of percutaneous cryoablation among radiologists appears to be far lower than that of heat-based ablation techniques. The aim of this article is to outline specific aspects of cryoablation and to illustrate its potential clinical applications with case presentations.Key Points• Recent advances have made cryoablation suitable for percutaneous use by radiologists with image guidance.• Cryoablation has distinct advantages over heat-based ablation techniques.• Cryoablation is becoming increasingly popular for lung, breast, kidney, bone, and soft tissue tumours.
Primary splenic angiosarcoma is a rare abnormality and has a bad prognosis. It has unknown pathogenesis. This abnormality is usually presented by splenic rupture. Surgery is the most promising treatm Surgery is the most accepted and accurate method for diagnosis and treatment. Surgery before rupture increases the life expectancy. A 65-year-old woman who presented to the emergency room with abdominal pain, abdominal distension, and anemia was found to have a splenic mass and massive ascites. After getting a hemorrhagic sample from the abdomen, the patient was operated with splenic rupture prediagnosis. The spleen material was reported as splenic angiosarcoma. The staging 18F-FDG-Positron Emission Tomography-Computed Tomography did not show any metastasis. Five months later, paclitaxel treatment was initiated upon liver and bone metastasis, and the treatment still continues. Splenic angiosarcoma has a place among splenic parenchymal lesions. The splenectomy material names the diagnosis. Pathologic examination of splenectomy material is revealed certain diagnosis.
ÖZRetroperitoneal sarkomların en sık görülen histolojik tipi liposarkomdur. Renal papiller kanserler renal hücreli kanserlerin %10'unu oluştururlar ve nefrektomi ile tedavi edilirler. Biz burada, retroperitoneal dev liposarkom ve renal papiller kanserin birlikte görüldüğü nadir bir olguyu sunduk.Altmış bir yaşında erkek hastada karında şişlik ve ağrı şikayeti nedeni ile yapılan tetkiklerinde retroperitoneal alanı ve karın içini dolduran yaklaşık 50x30cm boyutlarında liposarkomla uyumlu kitle ve ayrıca sol böbrek üst polde 6x8 cm'lik ayrı bir lezyon tespit edildi. Operasyonda biri yaklaşık 40x35cm, diğeri 30x20cm olmak üzere iki parça halinde dev kitle eksize edildi. Sol böbrekten kaynaklanan kitleden intraoperatif biopsi alınarak frozen inceleme yapıldı. Malign olması nedeni ile sol nefrektomi yapıldı. Dev kitlenin histopatolojik incelemesinde dediferansiye liposarkom olduğu ve sol nefrektomi materyalinde de renal papiller hücreli kanser olduğu raporlandı. Retroperitoneal dev liposarkom vakalarında eşzamanlı ikinci primer tümörlerin görülebileceği, bunların ameliyat öncesi tetkiklerle tespitinin yapılıp tedavi edilmesi gerekliliği akılda tutulmalıdır.Anahtar kelimeler: Retroperiton, Liposarkom, Renal papiller kanser IntroductionRetroperitoneal sarcomas are rare tumors that account for 15% of all soft tissue sarcomas. The most common histological type is liposarcoma (41%) [1]. Because of its characteristic deep location, retroperitoneal liposarcomas are difficult to be diagnosed. While intra-abdominal mass effects are the most common symptoms present in 80% of patients, pain is the second common symptom [2]. Computed tomography (CT) scan, magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) are diagnostic examinations with unique findings [3]. The gold standard for the treatment is surgery [1]. On the other hand, renal papillary cancer (RPC) accounts for 10-15% of all types of renal cell cancers and it is the second common type. The primary treatment of RPC is nephrectomy [4]. ABSTRACTThe most common histological type of retroperitoneal sarcomas is liposarcoma. Renal papillary cancers account for approximately 10% of all known renal cell cancers and nephrectomy is the preferred choice for the treatment in suitable cases. In this report, we presented a concurrency of giant retroperitoneal liposarcoma and renal papillary cancer in a 61-year-old male patient. He was referred to our clinic with complaints of abdominal distension and pain. Computed tomography (CT) scan, magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) revealed a giant mass filling intraabdominal and retroperitoneal space, approximately 50x30 cm in size and also a separate mass which is 6x8 cm in size in the upper pole of the left kidney. The giant mass was excised in two separate pieces. After frozen section procedure, nephrectomy was performed for mass arising from the left kidney. Histopathological analysis of the large masses, revealed dedifferentiated liposarco...
