A Case Report of Acute Acalculous Cholecystitis and Acute Hemorrhagic Cystitis Due To Salmonella Typhi
(Hindawi Ltd, 2014) Polat, Hatice Beyazal; Beyazal, Mehmet; Celiker, Fatma Beyazal
Acute acalculous cholecystitis and acute hemorrhagic cystitis due to Salmonella Typhi are a rare condition. A 24-year-old female patient was admitted to our clinic with abdominal pain, nausea, fever, headache, urinary burning, and bloody urine. Based on clinical, laboratory, and radiological evaluations, the patient was diagnosed with acute acalculous cholecystitis and acute hemorrhagic cystitis due to Salmonella Typhi. The patient was treated with intravenous ceftriaxone for two weeks. After the treatment, the patient's clinical and laboratory findings improved. Acute acalculous cholecystitis due to Salmonella Typhi concomitant with acute hemorrhagic cystitis is very rare and might be difficult to diagnose. Infectious agents such as Salmonella Typhi should be considered when acute acalculous cholecystitis and acute hemorrhagic cystitis are detected in adult patients with no underlying diseases.
The Efficiency of Apparent Diffusion Coefficient Quantification in Diagnosis of Acute Cholecystitis and in Differentiation of Cholecystitis From Extrinsic Benign Gallbladder Wall Thickening

The aim of the current study was to assess the efficiency of the apparent diffusion coefficient (ADC) measurement in diagnosis of acute cholecystitis and in differentiation of cholecystitis from extrinsic benign gallbladder wall thickening. Forty patients who were diagnosed to have acute cholecystitis by ultrasonographic examination were included in this study. The control group consisted of 18 patients without symptoms of gallstones and cholecystitis whose gallbladder walls were thickened due to cirrhotic ascites. Both groups were examined using diffusion weighted imaging, and the mean ADC values were compared using Student's t-test. The diagnoses of the 40 patients were proven by histopathological examination. The mean ADC values of patients diagnosed with cholecystitis (1.68 +/- A 0.36 x 10(-3) mm(2)/s) were significantly lower than the mean ADC values of the control group (2.35 +/- A 0.24 x 10(-3) mm(2)/s) (p < 0.05). Receiver operating characteristics curve analysis based on ADC revealed a cut-off value of 2.04 x 10(-3) mm(2)/s for the diagnosis of cholecystitis, with a sensitivity of 94 % and a specificity of 89.7 %. ADC value quantification may be an efficient method for making a diagnosis of cholecystitis and in differential diagnosis of cholecystitis from the extrinsic benign gallbladder wall thickening that can be seen during the course of cirrhotic ascites.
A High Grade Gliomatosis Cerebri Case Report; Mr, Diffusion Mr and Mr Spectroscopy Findings
(Turkish Neurological Soc, 2014) Beyazal, Mehmet; Unal, Ozkan; Yilmazer, Gokhan; Celiker, Fatma Beyazal; Tombul, Temel
Gliomatosis cerebri is a rare primary diffuse cerebral malignity. "It is characterized by the diffuse proliferation of neoplastic glial cells that involve more than two cerebral lobes. For a definitive diagnosis histopathological examination is required. Advanced magnetic resonance imaging techniques are very useful in the pretreatment diagnosis-staging and post-treatment follow-up. In this report a patient with gliomatozis cerebri was presented with magnetic resonance, diffusion weighted imaging and magnetic resonance spectroscopy findings. In addition, the importance and the role of magnetic resonance spectroscopy in the diagnosis and staging of gliomatosis cerebri is discussed.
