A large abdominal mass was found in a 19-year-old woman presenting with an increasing subcostal pain that initially appeared 6 months before. Abdominal computed tomogra-phy (CT) examination revealed a 21.5 × 15 × 21 cm giant splenic cyst (Fig. 1) that was hyperintense on both T1-and T2-weighted MR images suggesting a mixed hemorrhagic and protein-r...

Case A 65-year-old woman presented with a three-month history of persistent ocular-nasal catarrh, sub-febrile state, myalgia, night sweats, weight loss and early daily bi-temporal pain. Severe biological inflammatory syndrome with CRP at 105 mg/l and sedimentation rate at 97 mm was present. Colour Doppler Ultrasound (CDU) (Figure 1) showed a typica...

We report a rare case of purely retrograde stenosing stricture of the sigmoid descending colonic junction fortuitously diagnosed during the waning of a failed virtual colonoscopy in a 69-year-old patient. The rather asymptomatic patient was addressed to investigate a positive fecal occult blood test. He had suffered a single acute colonic diverticu...

We report a very rare case of acute congestive ischaemic colitis of the left colon caused by brutal decompensation of an uncommon arteriovenous malformation (AVM) in the territory of the inferior mesenteric artery (IMA) in a 45-year-old male patient. The patient presented with severe abdominal pain in the left iliac fossa and abundant mucoid stools...

We report a very rare case of acute obstructive hemobilia caused by bleeding of a mass-forming intrahepatic cholangiocarcinoma in a 75-year old man. The prompt complete emergency diagnosis was made by ultrasound and confirmed by MDCT. The features of hemobilia and intrahepatic cholangiocarcinoma are briefly reviewed.

Solitary fibrous tumor (SFT) is an unusual spindle cell neoplasm rarely described in the kidney. Usually occurring in the pleura, it has also been described in various extrapleural sites. We report a rare case of SFT of the kidney fortuitously found in a 55-year-old patient. The imaging features are illustrated. The definite diagnosis was made thro...

We report the CT, surgical and histopathologic findings of a rare case of Hepatic Angiosarcoma (HAS) diagnosed in a 85-year old women 65 years after Thorotrast (Th-232) exposure for angiography. At the early arterial phase of dynamic MDCT, peripheral curvilinear and central nodular puddling of contrast produced in the 8 cm tumor. Then progressive c...

We hereby report a case of diffuse pelvic peritoneal involvement by immunoglobulin G4-related disease (IgG4-RD). Numerous pelvic masses and nodules showing delayed enhancement on enhanced abdominal CT were found to congregate in the pelvic organs of a 57-year-old female presenting with intestinal subocclusion. The differentiation between peritoneal...

We present the case of a patient who died from multiple organ failure due to acute liver failure as a result of malignant hepatic infiltration by an adenocarcinoma. A review of the literature revealed that the clinical picture, laboratory examination, and imaging studies do not contribute to the diagnosis of this rare cause of liver failure. Theref...

We present the case of a 26-year-old man with schizoid personality disorder who suffered from a very focal and transparietal necrosis of the sigmoid after an overdose of atypical neuroleptics. This is a singular, rather unknown and potentially lethal side effect of these drugs. The physiopathology of this complication is multifactorial.

Sinonasal myospherulosis is a foreign body reaction to lipid material used on nasal packing at the conclusion of paranasal sinus surgery. Rare cases have been sporadically reported. We report a case found in a 79-year-old female 8 months after functional endoscopic sinus surgery during which sinus cavities had been packed with gauze coated with Ter...

Imaging findings of amyloid infiltration of the greater omentum, mesentery, and retroperitoneal spaces have only extremely rarely been reported in the radiological literature. This report illustrates the MDCT findings fortuitously found in a 70-year-old male presenting with a known latent myeloma. Extra abdominal deposits—axilla and cardiophrenic a...

Whether extragonadal germ cell tumors develop primarily in the retroperitoneum or whether they are essentially metastases of a primary testicular tumor has long been debated and remains controversial. Three patients presenting with apparent primary extragonadal retroperitoneal germ cell tumors are reported. Ipsilateral testicular evaluation was ext...

Inflammatory Fibroid Polyp (IFP) is an extremely rare tumour involving the gastrointestinal tract (GI) and especially the stomach and small bowel. It presents either as a solitary large or sessile lesion arising from the submucosa and despite a large size and sometimes infiltrating growth, the tumour is always benign and has a good prognosis. Histo...

Background. MDCT currently frequently represents the first choice modality for imaging in acute or subacute abdominal conditions implicating the small bowel. As a consequence, the MDCT features of intestinal carcinoid tumors and of their peculiar metastatic spread have to be known by abdominal radiologists. Patients and methods:These features are d...

As a consequence, the MDCT features of intestinal carcinoid tumors and of their peculiar metastatic spread have to be known by abdominal radiologists. These features are described and illustrated in the r...

It has been previously shown that S100A2 is downregulated in tumor cells. The level of immunohistochemical S100A2 expression was therefore characterized in 424 normal and tumoral (benign and malignant) tissues of various origins, but mostly epithelial (with either glandular, squamous, respiratory or urothelial differentiation). We also investigated...

The current study deals with the setting up of a new tool that enables the benign versus the malignant nature of colorectal adenomas to be determined accurately. The 2 objectives are to determine (1) whether adenomas should, or should not, be included in a 2- or a 3-tier grading system, and (2) whether severe dysplasias and carcinomas in situ share...

Cell-matrix interactions are governed by a distinct set of proteins, with 2 nonintegrin laminin-binding proteins, galectin-1 and galectin-3, providing 1 aspect. The expression patterns of laminin and the 2 galectins and galectin binding sites were quantitatively determined by means of computer-assisted microscopy with the aim of differentiating bet...
