Although MRI has become widely used in small animal practice, little is known about the validity of advanced MRI techniques such as diffusion-weighted imaging and diffusion tensor imaging. The aim of this retrospective analytical observational study was to investigate the characteristics of diffusion parameters, that is the apparent diffusion coefficient and fractional anisotropy, in dogs with a solitary intracranial meningioma or histiocytic sarcoma. Dogs were included based on the performance of diffusion MRI and histological confirmation...

Inflammatory myofibroblastic tumors (IMTs) are uncommon breast lesions that consist of spindle cells accompanied by plasma cell-rich inflammatory infiltration, which may mimic breast cancer clinico-radiologically. A woman aged 38 years with a breast mass was referred to our general surgery clinic. The physical examination revealed a mass with irregular borders in the upper outer quadrant of the left breast. In mammography, the lesion was 15 mm in diameter with a spheric form and high density. Ultrasonographically, the mass was solid, heterogeneous, and hypoechoic with posterior enhancement...

BACKGROUND: Pheochromocytoma (PHEO) is a rare tumor of the adrenal medulla and sympathetic ganglion that produces the catecholamines norepinephrine and epinephrine. Traditionally, approximately 10% of PHEOs were thought to be malignant, but recent developments in PHEO research have noted that specific genetic mutations are associated with higher risk of metastatic spread. CASE REPORT: We report the case of a 71-year-old female who presented with abdominal pain in September 2009 when she was 64 years old...

T2 (tumor invades perimuscular connective tissue; no extension beyond serosa or into liver) gallbladder cancer has generally been treated by S4aS5 subsegmentectomy (S4aS5 HR). We investigated the therapeutic effect of full-thickness cholecystectomy (FC) and gallbladder bed resection (GBR), in terms of tumor location and resection margin (distance from the tumor). At our department we employ the following protocol to determine the extent of resection needed to achieve R0 status: (1) A tumor located in the gallbladder fundus (Gf) or body (Gb) and only on the free peritoneal side was classified as P-type, for which full-thickness cholecystectomy and regional lymph node dissection were performed...

Background and importance The marginal tentorial artery runs over the free edge of the tentorium. Different origins have been described, always involving branches of the carotid artery. We report the superior cerebellar artery as an unknown origin of this artery. We developed our strategy in a case of a tentorial meningioma mainly supplied by this artery. Clinical presentation A 53-year-old man was admitted in our institution for the surgical treatment of a large tentorial and petroclival meningioma. A 2D conventional angiogram was insufficient to detect the tumoral blush...

BACKGROUND: Patients with a history of prior breast augmentation and newly diagnosed breast cancer represent a rapidly expanding and unique subset of patients. Prior studies have described changes in breast parenchyma and characteristic body habitus of previously augmented patients, as well as increased rates of capsular contracture associated with breast conservation therapy. In our current study, we aimed to study the risk factors contributing to morbidity and whether recurrence rates are higher in patients with prior breast augmentation undergoing lumpectomy or mastectomy for breast cancer and identify differences in complications between these 2 groups...

BACKGROUND: Increasing number of patients with preexisting breast implants desire breast conservation therapy for breast cancer. There is paucity of comparative data on tumor margins and re-excisions in these patients. High re-excision rates up to 25% have been reported in breast conservation therapy patients; efforts to obtain cosmesis and avoid implant rupture might increase this further. We analyzed tumor margins, re-excision rates, and recurrence in previously augmented versus non-augmented patients undergoing lumpectomy for breast cancer...

BACKGROUND: Margin-free en bloc resection is the best medical practice for primary vertebral chordoma and chondrosarcoma. Spinal reconstruction following total spondylectomy requires reconstructive interbody graft (allograft, devascularized autograft, vascularized autograft, or cage constructs) and instrumentation. An important consideration when choosing grafts and instrumentation is the durability and the long-term success of the fusion without subsidence. OBJECTIVE: To evaluate the potential use of vascularized fibular autograft as a reconstructive strategy after en bloc resection...

Nucleic acid aptamers are becoming popular as molecular probes for identification and imaging pathology and, at the same time, as a convenient platform for targeted therapy. Recent studies have shown that aptamers may be effectively used for tumor characterization and as commercially available monoclonal antibodies. Here we present three DNA aptamers binding to whole transformed lung cancer tissues, including tumor cells, connective tissues, and blood vessels. Protein targets have been revealed using affinity purification followed by mass spectrometry analyses, and they have been validated using a panel of correspondent antibodies and 3D imaging of tumor tissues...
