Dysphagia in multiple sclerosis: from pathogenesis to diagnosis

Abnormalities of swallowing are commonly encountered in Multiple Sclerosis (MS), especially in the most disabled patients. The disturbances usually involve oral and pharyngeal phases of swallowing, although upper oesophageal sphincter dysfunction has also been detected. MS patients need to be effectively evaluated and managed in order to recognize dysphagia before any medical complications such as aspiration pneumonia appear. An integrated approach is proposed to define the severity of dysphagia and to devise the most appropriate therapeutic/rehabilitative methodology.

Systemic sclerosis in aquaporin-4 antibody-positive longitudinally extensive transverse myelitis

We report on the first patient with a relapsing, anti-aquaporin-4 (AQP-4) antibody-positive, longitudinally extensive transverse myelitis (LETM) who developed systemic sclerosis (SSc). A 62-year-old woman, who presented with bilateral, distal lower limb and perineal numbness, developed clinical manifestations and paraclinical features of SSc. Spinal cord imaging revealed lesions that were consistent with LETM. Patients serum was positive for neuromyelitis optica (NMO)-IgG/AQP-4 antibodies. High-dose intravenous corticosteroids improved the neurological symptoms. The present case expands the list of autoimmune systemic diseases that occur in neuromyelitis optica spectrum disorders associated with NMO-IgG/AQP-4 antibodies.

Differential diagnosis of Krukenberg tumors using multivariate analysis.

Aims and Background Krukenberg tumors are ovarian metastases from a gastroenteric malignancy in 90% of cases. At present, diagnostic imaging techniques (US, CT, MRI) do not provide any reliable diagnostic criteria to differentiate these metastases from ovarian primaries. We tried to use multivariate analysis to distinguish malignant ovarian primaries from Krukenberg tumors based on their differential natural history. Patients and Methods We retrospectively compared the CT findings of Krukenberg tumors (47 patients, 79 masses, only from gastroenteric malignancy) with CT findings of primary epithelial ovarian cancers (46 patients, 67 masses). We compared the same independent variables in the two groups: age, morphology, margins, carcinomatosis, bilateral versus unilateral involvement, ascites, lymph node involvement, metastases on the basis of multivariate analysis. Results According to the best fitted model, clear-cut margins (OR: 3.75; 95% Cl: 1.14-9.72) and the presence of carcinomatosis (OR: 4.21; 95% Cl: 1.51-11.72) were the strongest predictors of a diagnosis of Krukenberg tumor. In contrast, the presence of ascites was more likely to be a protective factor (OR: 0.22; 95% Cl: 0.08-0.62). Conclusions We can try to make a differential diagnosis between a metastatic lesion from the gastroenteric tract and a primary adnexal lesion based on the multivariate statistical analysis of intraperitoneal spread of the different types of cancer rather than on morphologic findings at CT.

SPONTANEOUS HEMORRHAGE OF A LIVER METASTASIS FROM SQUAMOUS CELL CERVICAL CARCINOMA : CASE REPORT AND REVIEW OF THE LITERATURE

Liver metastases are an uncommon cause of spontaneous bleeding compared with primary benign/malignant liver lesions. Since metastatic lesions tend to maintain the vascular characteristics of the primary tumor, some metastases have a greater proclivity for hemorrhage into the host organ than others. We describe the clinical and computed tomography (CT) features of a patient previously treated for nonkeratinizing small cell squamous carcinoma of the cervix uteri. As the metastatic rupture was diagnosed while still intraparenchymal and subcapsular, with minimal peritoneal reaction, the patients outcome was favorable.

Extraperitoneal pelvic leiomyosarcoma. MR findings in a case

The magnetic resonance imaging (MRI) of a patient with nongynecologic pelvic leiomyosarcoma is presented. A retroperitoneal mass appeared under the broad ligaments, in the right paravesical and parametrial, lateral pararectal site. The mass leaned on the uterus and vagina. On MRI, the mass had solid structure, isointense on T1-weighted images, inhomogeneously iperintense on T2-weighted images with central areas of increased intensity. Late after contrast agent administration, the mass appeared inhomogeneously ipointense with areas of fair late contrast enhancement. The morphology of the tumor, the retroperitoneal site, and MRI sequences make the differential diagnosis. These evidences were useful in treatment planning.

Magnetic resonance appearance of endometrial sarcoma: report of a case with unusual findings.

We report the MR findings of an endometrial stromal sarcoma. The uterus was enlarged and completely replaced by neoplastic tissue, with full-thickness myometrial infiltration. It had isointense signal on T1- and irregularly hyperintense signal on T2-weighted images and the dynamic study with intravenous gadoteridol showed centripetal enhancement. This sarcomatous-like pattern correlates well with the pathologic and CT findings reported in the literature.

Multiple nodular metastases in mesenteric panniculitis by uterine papillary serous adenocarcinoma (upsc):: CT Appearance of a case

Intra-abdominal panniculitis is a thickening of the mesentery of the small/large intestine due to infiltration of lipid-laden macrophages associated with a variable amount of fibrosis. This condition is rarely associated with malignant neoplasms. We report the computed tomography (CT) findings of a patient treated for uterine papillary serous adenocarcinoma (UPSC). She had mesenteric panniculitis where metastatic tumor nodules implanted. This was the only intraperitoneal recurrence. To our knowledge, no such finding has been reported in the gynecologic and radiologic literature to date. On CT images, the differential diagnosis is with cystic dilatations of mesenteric lymph vessels.

Epithelial ovarian cancer in female pseudohermaphroditism. A diagnosis by computed tomography and review of the literature.

We describe the case of a patient proven to be a female pseudohermaphrodite with a complete virilization syndrome who developed an epithelial tumor of the ovary of borderline malignancy. The tumor appeared as an abdominal mass with cystic features on ultrasonography. The diagnosis of the intersexual condition and adnexal cancer was made by computed tomography (CT).
