Large Mesenteric Cyst Mimicking Tuberculous Ascites

Background. Intraabdominal lesions such as mesenteric cysts are uncommon disorders. Most are discovered incidentally during routine abdominal examinations. Methods. We report a patient with a mesenteric cyst masquerading as tuberculous peritonitis and ascites. Conclusion. Mesenteric cysts generally do not show typical clinical findings. They may also present with peritoneal tuberculosis findings such as low albumin gradient ascites with high ascitic adenosine deaminase levels. Surgery is used to remove a wide variety of mesenteric cysts. A correct diagnosis can be made by the combined use of radiographic and sonographic examinations in conjunction with the clinical signs

The value of diffusion-weighted imaging and apparent diffusion coefficient quantification in the diagnosis of perforated and nonperforated appendicitis

PURPOSEWe aimed to evaluate the effectiveness of diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) values in the diagnosis of acute appendicitis and differentiation of perforated and nonperforated appendicitis cases, with histopathologic correlation. MATERIALS AND METHODSSixty consecutive patients (34 males, 26 females; mean age, 35.6±15.5 years; range, 17–83 years) with a presumptive diagnosis of acute appendicitis were included in this prospective study. With a 1.5 Tesla MRI unit, DW-MRI examinations were performed with b values of 50, 400, and 800 s/mm2. The mean ADC values of case and control groups, as well as in perforated and nonperforated groups were compared. RESULTSOf the 60 cases, 44 had a radiological diagnosis of acute appendicitis, and 16 were regarded as normal. Of the 40 patients who underwent surgical operation, 12 had a histopathological diagnosis of perforated appendicitis, and 28 had nonperforated appendicitis. Mean ADC value in patients with acute appendicitis (1.01±0.26×10-3 mm2/s) was lower than the control group (1.85±0.13×10-3 mm2/s) (P < 0.001). Mean ADC value of the perforated group (0.79±0.19×10-3 mm2/s) was lower than the nonperforated group (1.11±0.22×10-3 mm2/s) (P < 0.001). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy rate of DW-MRI in the diagnosis of acute appendicitis were 97.5%, 100%, 97.5%, 100%, and 98.1%, respectively. CONCLUSIONDW-MRI and ADC quantification are effective in the diagnosis of acute appendicitis, both in perforated and nonperforated cases

Intrabiliary rupture of liver hydatid cyst: a case report and review of the literature

Herein, we report a 66 year old woman who was diagnosed to have intrabiliary rupture of liver hydatid cyst with demonstrative computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography findings, with a review of the literature

Coexistence of Neurofibromatosis Type-1, Left Internal Carotid Artery Hypoplasia and Left Phytisis Bulbi

Congenital abnormalities of the internal carotid artery (ICA) are extremely rare and aplasia/hypoplasia of the ICA associated with other congenital malformations is uncommon. An 8-year-old male patient was admitted to our hospital for extreme nervousness, attention problems and hyperactivity. On MR examination, left phytisis bulbi, left frontal lobe atrophy, assymmetric dilataion in the left lateral ventricle and hamartomas in both globus pallidi, right thalamus, and bilateral cerebellar hemispheres posterior to the fourth ventricle were observed. Left ICA was observed as hypoplastic in the cervical and cranial MR-angiography. Left MCA and ACA could not be visualised. Left carotid canal hypoplasia and left sphenoidal bone dysplasia were detected on CT. As far as we know, only 4 cases with concomitancy of ICA hypoplasia-NF Type-1 have been reported up to the present. In our case, in addition, phytisis bulbi is accompanying this coexistence

Sonographic Elastography of the Thyroid Gland.

Thyroid gland disorders include benign and malignant thyroid nodules and diffuse thyroid disorders. The incidence of malignant thyroid nodules is low and the prognosis is good. The diagnosis of thyroid cancer and diffuse parenchymal disorders is generally based on clinical manifestations and histopathological evaluation. Ultrasonography has its place in the diagnostics and follow-up of thyroid disorders. Ultrasonographic elastography is a new, developing method that shows increase in clinical practice. In this study, we aimed to review the data on thyroid ultrasound elastography
