Syuichi Tetsuka, Hiroaki Nonaka
BACKGROUND: Severe haemolysis, elevated liver enzyme levels, and low platelet count (HELLP) syndrome in pregnancy are possible underlying trigger factors for posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging (MRI) shows diffuse signal abnormalities involving the subcortical white matter in the parieto-occipital lobes. Although the diagnosis of RPES was clearly established by the distinctive reversibility of clinical and radiological abnormalities, it is difficult to distinguish from differential diagnosis...

Endovascular aortic aneurysm repairs rely heavily on radiologic imaging modalities for preoperative surveillance, intraoperative management, and postoperative follow-up. Ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography all have utility at different stages of management. Often one imaging modality compliments another by providing supplementary information. Data from the imaging exams must be synthesized into one coherent plan for managing patients with aortic aneurysms...

BACKGROUND: Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue neoplasm, and its rarity makes studying it difficult. We found that several of our patients with AFH presented with radiologically suspicious local lymph nodes that were sampled because of their imaging characteristics, but the nodes proved to be benign on pathologic evaluation. Although the frequency of this finding is unknown, it seems important for orthopaedic oncologists who care for patients with AFH to know whether suspicious-appearing associated nodes in these patients warrant aggressive management...

Serous cystadenomas of pancreas are unusual cystic tumour. The microcystic forms is more common and its radiological diagnosis is easy. However, the macrocystic unilocular form of serous cystadenoma can be mistaken with other malignant macrocystic lesions of the pancreas. We report the case of a 17 year-old girl, admitted to the National Hospital of Niamey (Niger), with abdominal pain and an unilocular macrocystic serous cystadenoma of pancreas, diagnosed after histological examination of the surgical specimen...

Intrahepatic cholangiocarcinomas account for approximately 20% of cases of cholangiocarcinomas. Three growth patterns or morphologic subtypes exist, including mass-forming, periductal-infiltrating, and intraductal-growth subtypes. Knowledge of these morphologic subtypes and their radiologic appearance aids in timely diagnosis, a key to optimizing patient outcomes. The morphologic variability of intrahepatic cholangiocarcinomas has a direct impact on the diagnostic sensitivity and specificity of various diagnostic imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET)...

CASE SERIES SUMMARY: The aim of this retrospective case series was to describe seven cases where cats with primary lung tumours were presented because of metastases to extra-pulmonary sites ('feline lung-digit syndrome'). Specifically, we wanted to emphasise less typical case descriptions where tumour emboli resulted in lesions developing in the musculature (including the muscles of the head), skin or distal aorta. RELEVANCE AND NOVEL INFORMATION: The cases are presented to increase clinical awareness of this entity in feline practice, especially when characteristic combinations of clinical signs are present...

Breast metastases from extramammary cancers are rare and usually related to poor prognosis. The extramammary tumors most frequently exhibiting breast metastases are melanoma, lymphomas, ovarian cancer, lung, neuroendocrine tumors, and sarcomas. Due to the lack of reliable and specific clinical or radiological signs for the diagnosis of breast metastases, a combination of techniques is needed to differentiate these lesions from primary breast carcinoma or even benign breast lesions. Multiple imaging methods may be used to evaluate these patients, including mammography, ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET/CT)...

We present a case of a solitary fibrous tumour (SFT) resembling an aggressive angiomyxoma/liposarcoma on radiological imaging, causing significant diagnostic challenges preoperatively. A 76-year-old male was incidentally found to have a large pelvic mass on a CT scan. Further evaluation with an MRI scan confirmed a presacral mass containing fat and soft tissue components. It was inseparable from the sacrococcygeal spine, rectal serosa and the posterior wall of the urinary bladder, but no evidence of invasion was seen...

Lipomatous lesions are common musculoskeletal lesions that can arise within the soft tissues, bone, neurovascular structures, and synovium. The majority of these lesions are benign, and many of the benign lesions can be diagnosed by radiologic evaluation. However, radiologic differences between benign and malignant lipomatous lesions may be subtle and pathologic correlation is often needed. The use of sonography, computed tomography (CT), and magnetic resonance imaging (MRI) is useful not only in portraying fat within the lesion, but also for evaluating the presence and extent of soft tissue components...
