A 33-year-old immunocompetent man was admitted to the authors' hospital with a one-month duration of fevers, chills, and non-productive coughs, and suddenonset weakness and ischemic pain of both lower extremities. Physical examination revealed crepitating rales heard over bilateral lung fields. On auscultation, a grade 2~3/6 systolic murmur was heard over the leftlower sternal border and apical area. Transthoracic echocardiography revealed a mobile mass on the tricuspid valve compatible with vegetation, in addition to concomitant mitral valve vegetation (Video 1)...

INTRODUCTION: Ganglioneuromas are rare benign neoplasms of the sympathetic nervous system. We describe the case of an incidentally found ganglioneuroma in a woman. To our knowledge this is the first described case of robotic excision of a retroperitoneal ganglioneuroma. CASE: A 41-year-old female had an incidental retroperitoneal mass found during a routine US. CT scan and MRI showed an 8.3cm homogeneous mass, adjacent to left kidney upper pole, with peripheral contrast enhancement...

BACKGROUND: Image guidance for spine pain control procedures, including epidural steroid injection, nerve root block, and facet block, can be performed with either computed tomography (CT) or conventional fluoroscopy. CT has the advantage of improved anatomic localization and use of air for contrast; however, there are concerns that CT leads to higher radiation dose and longer procedure time. OBJECTIVE: To evaluate procedure time and radiation dose for multiple types of spine pain control procedures performed under CT guidance...

PURPOSE: Papillary renal cell carcinoma (P-RCC) typically exhibits a homogeneous, solid hypovascular mass; P-RCC with a cystic appearance is atypical. Tubulocystic RCC (TC-RCC), a newly proposed entity for renal tumors in the 2016 WHO classification, and cystic papillary RCC, may yield similar imaging findings. Therefore, we investigated the incidence of papillary RCC with cystic changes and compared its CT and pathologic features to differentiate between two entities. METHODS: We retrospectively evaluated 26 consecutive patients diagnosed with P-RCC...

BACKGROUND: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...

Renal angiomyolipomas are the most common renal mesenchymal tumors. While classic angiomyolipomas are benign, there are a number of other subtypes. Epithelioid variants are potentially malignant and may be indistinguishable from renal cell carcinoma on imaging. We present a 52-year-old woman who underwent left nephrectomy for an aggressive-appearing malignant renal epithelioid angiomyolipoma. At 6 months postoperatively, restaging FDG PET/CT demonstrated a hypermetabolic left adrenal mass extending to the left adrenal vein, left renal vein, inferior vena cava, and right atrium (SUVmax = 12)...

Renal Clear Cell Carcinoma (RCC) comprises over 80% of renal malignancies in adults. Thyroid gland metastasis is rare in RCC. Few studies have described cases of RCC mistaken for benign arteriovenous malformation (AVM). To the best of our knowledge, an AVM arising from underlying RCC metastasis to the brain has not yet been reported. The current study presents a case of RCC metastasis to the thyroid gland, with an AVM identified to be a result of metastatic involvement in the brain. A 45-year-old African-American female presented with left-sided weakness, slurred speech, facial droop and seizure...

PURPOSE: Carboplatin clearance is correlated with glomerular filtration rate (GFR) and usually estimated with creatinine clearance using Cockcroft-Gault (CG) formula. Because plasma creatinine level is highly correlated with muscle mass, we hypothesized that an abnormal body composition with a low lean body mass (LBM) percentage [(LBM/weight) × 100] may result in inadequate carboplatin dosing. Serum cystatin C is an alternative marker of GFR, not affected by muscle mass. We aimed to investigate the influence of total LBM and LBM percentage on GFR calculation, using creatinine (CrCl) or cystatin C (GFRcysC-creat) in cancer patients...

A 51-year-oldwoman with a right renal mass was referredto our hospital. Computedtomographic (CT) scan demonstrated a 30 mm-diameter renal mass with delayed enhancement. She underwent a robotassistedlaparoscopic right partial nephrectomy. The pathological examination showedthat tumor cells with eosinophilic, clear cytoplasm formedtubules of various sizes containing colloid-like material, which resembled the findings of thyroidfollicular carcinoma. The tumor was immunoreactive for vimentin andcytokeratin (CK) 7, whereas it lackedreactivity for thyroidtranscription factor-1 (TTF-1) or thyroglobulin...

Metastatic renal cell carcinoma (MRCC) is a rare cause of massive lower gastrointestinal bleeding (LGIB). We report a 51-year man who underwent left nephrectomy for renal cell carcinoma (RCC) 6 years ago. presenting with massive LGIB. Preoperative abdominal computed tomography (CT) revealed small bowel mass. Exploration of the abdomen revealed jejunal mass. Resection of the mass along with the jejunal segment with end-to-end anastomosis was performed. Histopathology of the jejunal mass confirmed MRCC. MRCC should be expected as a source of massive LGIB in a patient with history of RCC...

CASE SUMMARY: A 9-year-old male neutered domestic shorthair cat presented with anorexia. Ultrasonography showed an irregularly shaped hypoechoic mass in the cranial pole of the right kidney. Ultrasound-guided fine-needle aspiration of the renal mass was performed. Cytology revealed moderate cellularity smears composed of epithelial cell clusters, which consisted of an exclusive population of oncocytic cells seen in sheets and papillary clusters along with abundant single cells. A moderate-to-abundant amount of densely stained granular cytoplasm with round nuclei and indistinct nucleoli was seen...

A 21 year-old male underwent nephrostomy tube insertion for hydronephrosis due to a large para-aortic adenopathy of a testicular tumor. In order to reduce infections during chemotherapy, a ureteral stent was placed. While removing the nephrostomy tube, a pulsatile bleeding was found and a renal angiography was done. A pseudoaneurysm of his first left lumbar (L1) artery communicating with the nephrostomy's access site was found. An embolization was performed with coils in the left L1 artery and one of its subdivisions...

Breast metastases of solid extramammary tumors are very rare in comparison to primary malignancies of the breast and account for only 0.33-6.3% of all malignant neoplasms of the breast. The most common primary tumors are malignant melanoma, distant sarcomas, lung cancer, ovarian cancer, renal cell cancer and thyroid cancer in decreasing order of frequency. This review article summarizes the clinical features and the different imaging findings of breast metastases from different extramammary solid tumors. Breast metastases are often incidental findings in computed tomography (CT) or positron emission tomography CT (PET-CT) imaging...
