Retrospective Evaluation Of MRI Findings Of Knee Joint In 255 Patients

Retrospective evaluation of knee MRI obtained from 255 cases and to demonstrate most common knee joint pathologies in our region.In our study knee joints of 255 cases who admitted to different clinics of our hospital with various complains of knee between October 1996 and December 1998 were examined in wide spectrum with MRI. Via 1.0 Tesla MRI device and special knee coil in sagittal, coronal and axial plains MRI images were obtained. The number of male and female patients were 173 and 82 and their ages were ranged between 14 and 70, and the mean age was 3413.The most common knee pathologies were intra-articular fluid (%58.04), medial (%46,66) and lateral (%12.55) meniscal injuries, anterior cruciate ligament injury (%17.25) and osteoarthritis (%14.9). The other important lesions were degeneration of medial and lateral meniscus, Baker’s cyst, bursitis, posterior cruciate ligament injury , medial and lateral collateral ligament injuries, synovial hypertrophy, chondromalasia of patella, and contusion.In our images of knee the most common lesions were injuries of meniscus and ligament. Because of being noninvasive technique for knee joint pathologies, capacity of multiplanar imaging, high contrast resolution and chance of detailed anatomic evaluation MR imaging was found to be most appropriate imaging technique for knee joint pathologies

Pancreatic Divisum Associated with Ampullary Neuroendocrine Tumor and the Role of Magnetic Resonance Imaging

Pancreatic divisum is the most common anomaly of the pancreas. Pancreatic divisum associated with malignant tumor is rarely seen. The ampulla of Vater is formed by the union of the common bile duct and the pancreatic duct. The incidence of malignant tumor in the ampulla of Vater is very low. Adenomas and carcinomas are more common. Neuroendocrine tumors originate from enterochromaffin cells of the neuroendocrine system. Ampullary neuroendocrine tumors are very rare and preoperative diagnosis is very difficult. In the literature, the emphasis on imaging characteristics of similar cases is limited. Herein, we present a rare case of pancreatic divisum associated with ampullary neuroendocrine tumor and its characteristics of computed tomography and magnetic resonance imaging

The Imaging Findings of Duodenal Adenocarcinoma in Patient with Celiac Disease

Small intestine tumors are extremely rare. They account for approximately 1-5% of all gastrointestinal tumors. However, the risk of development of small intestine tumor increases in patients with celiac disease. Celiac disease is also known as gluten-sensitive enteropathy. Lymphoma is the most common small intestine tumor in patients with Celiac disease. Adenocarcinoma and adenoma of the small intestine are less common. Adenocarcinoma is frequently seen in the proximal segments of the small intestine. The prognosis of adenocarcinoma is worse than lymphoma. In the literature, there are few reported cases of duodenal adenocarcinoma in patients with Celiac disease and the imaging findings were not emphasized enough. For this reason, in this study, computed tomography and magnetic resonance imaging findings in a patient with duodenal adenocarcinoma associated with Celiac disease are presented

Polysplenia with Kartagener’s Syndrome: Case Report

Kartagener’s Syndrome is a rare congenital malformation andcharacterized by the triad of bronchiectasis, sinusitis, and situs inversus.The genetic disorder is at cilia. We presented our 13 years old patientdiagnosed as Kartagener’s syndrome with polysplenia by imaging findings.In recurrent airway infections, Kartagener’s syndrome must be kept in mindas one of the reasons

INFANTILE OSTEOPETROSIS ASSOCIATED WITH RICKETS

A 3-year-old female child was diagnosed as malignant autosomal recessive form of infantile osteopetrosis by presence of anemia, thrombocytopenia, hepatosplenomegaly, failure to thrive, visual and hearing loss, and the typical radiological images on plain radiograms. The patient had associated clinical and laboratory findings of rickets as a rare presentation. Treatment with calcitriol was initiated with a short-term calcium supplement

Volume changes in the gallbladder in association with various radiologic examinations.

PURPOSE: Our aim was to evaluate with sonography the volume changes of the gallbladder after intravenous administration of nonionic, iodinated contrast agents with or without ingestion of contrast agent or water. METHODS: A total of 191 patients received intravenous injection of 50 ml of nonionic contrast agent (Group A), intravenous injection of 100 ml of contrast medium (Group B), intravenous injection of 100 ml of contrast medium together with ingestion of 1000 ml of a dilute solution of contrast medium (Group C), or 1000 ml of water taken orally (Group D). The gallbladder volume was measured by ultrasonography in the fasting state in all groups, 15 minutes after intravenous injection of contrast medium in Groups A, B, and C and 30 minutes after water ingestion in Group D. RESULTS: In all groups, the volume of the gallbladder was statistically lower after the procedure than before. There was no significant difference among the groups in terms of this gallbladder volume change. CONCLUSIONS: Intravenous injection of nonionic, iodinated contrast medium or ingestion of water or a dilute solution of contrast medium for various radiological examinations results in contraction of the gallbladder. Contrast-enhanced radiological examinations may interfere with sonographic evaluation of the gallbladder. If necessary, gallbladder ultrasonographic examination should be repeated with the patient in a fasting state. (c) 2005 Wiley Periodicals, Inc. J Clin Ultrasound 33:214-217, 2005

A case of brucellar spondylodiscitis involving the cervical spine

Geyik, Mehmet Faruk/0000-0002-0906-0902; NAS, Kemal/0000-0002-5845-0851WOS: 000267573700009PubMed: 20023340We have presented a patient of 71-year-age with brucellar spondylodiscitis, involving the cervical spine, especially the C3-C4 segment. The patient had painful percussion of the cervical spine and passive mobilization of the neck, decreased range of motion, and cervical paravertebral tenderness; but no abnormalities observed on neurological examination. Wright agglutination test for brucella was positive at 1/320. Cervical localization for brucellar spondylodiscitis is an unusual case and should be detected and treated as early as possible. In endemic regions, spinal involvement of brucellosis should be considered in cases with fever, neck and low back pain

Dyke-Davidoff-Masson syndrome (cerebral hemiatrophy): Radiological findings

Objective: The aim of this study was to present cross- sectional cranial imaging findings of cases with Dyke-Davidoff-Masson syndrome (DDMS). Methods: The findings of 16 cases in whom unilateral cerebral hemispheric atrophy was detected at computed tomography and/or magnetic resonance imaging were retrospectively evaluated. The cases consisted of 8 females and 8 males, the ages ranged between 5 and 53 (mean:24). Six of the cases were children and 10 were males. Five of the patients had CT and 13 had MRI scan. The images were retrospectively evaluated and cerebral parenchymal findings and compensatory cranial findings were noted. Results: All cases had unilateral cerebral hemispheric atrophy, ipsilateral cortical sulcal and lateral ventricular dilatation. Together with hemispheric atrophy ipsilateral atrophy of corpus callosum in 6 cases (37.5%), ipsilateral thalamic atrophy in 13 cases (81%), ipsilateral parahippocampal atrophy in 8 cases (50%), ipsilateral cerebral pedincular atrophy in 7 cases (44%) and ipsilateral pontine atrophy in 3 cases (19%) were detected. Gliotic signal changes were observed in 13 cases (81%). Of compensatory findings, unilateral calvarial thickening was focal in 4 cases (25%), and diffuse in 12 cases (75%). There was expansion in ipsilateral half of frontal sinus in 15 cases (94%) and expansion in temporal bone aeration in 5 cases (31%). Conclusion: DDMS is a syndrome presenting with findings of cerebral hemiatrophy and calvarial hypertrophy. Cross-sectional radiological imaging findings may be variable among cases
