[A Gossypiboma (Textiloma) Mimicking a Gastrointestinal Stromal Tumor: A Case Report].

Gossypiboma (textiloma) is a rare but preventable complication occurring due to oblivion of the surgical material during an operation that carries important diagnostic difficulties as well as high morbidity and mortality risks. The actual incidence is unknown because of its medicolegal aspects. Our case is a 36-years-old female patient, who had a caesarean section two years ago in another center.

Evaluation of Arterial Stiffness in Patients with Behçet's Disease by Using Noninvasive Radiological Methods such as Intima-Media Thickness of the Carotid, Ankle-Brachial Pressure Index, Coronary Artery Calcium Scoring, and Their Relation to Serum Fetuin-A Levels: A Case-Control Study.

Background: Behçet's disease (BD) is a chronic, recurrent inflammatory systemic vasculitis. Evidence for increased atherosclerosis in BD has been observed. The relation between cardiovascular risk factors and increased atherosclerosis in patients with BD is still controversial.

Relationship Between Serum Fetuin-A Levels and Carotid Intima-media Thickness in Turkish Patients with Mild to Moderate Psoriasis. A Case-control Study.

Previous studies have associated severe psoriasis and psoriatic arthritis with an increased risk of atherosclerosis. However, the association between patients with mild-to-moderate plaque-type psoriasis and atherosclerosis has yet to be studied in depth. This study investigates a) possible correlations between carotid intima-media thickness (CIMT) and serum fetuin-A levels in patients with mild-to-moderate psoriasis and b) correlations between psoriasis severity index (PASI) and fetuin-A levels.

Fahr disease: use of susceptibility-weighted imaging for diagnostic dilemma with magnetic resonance imaging.

Fahr disease (FD) is a well-defined rare neurodegenerative disease that is characterized by idiopathic bilateral symmetric extensive striopallidodentate calcifications. The patients may present with diverse manifestations, most commonly movement disorder, cognitive impairment, and ataxia. Computed tomography (CT) is considered to be critical for accurate diagnosis because it is difficult to reliably identify calcifications by routine magnetic resonance imaging (MRI).

Anterior Sacral Meningocele Masquerading as an Ovarian Cyst: A Rare Clinical Presentation Associated with Marfan Syndrome.

Anterior sacral meningocele is a very rare clinical entity characterized by herniation of a meningeal sac through a sacrococcygeal defect. We report a case of a 20-year old female with Marfan syndrome who presented with abdominal distention that was misdiagnosed as an ovarian cyst on pelvic ultrasound. Pelvic magnetic resonance (MR) imaging showed large, well-defined multiloculated intrasacral and presacral cysts communicating via two separate broad necks and extending through defects in anterior aspect of sacral vertebrae.

Is there a role for DWI in the diagnosis of sacroiliitis based on ASAS criteria?

Purpose: Sacroiliitis based on MRI is one of the main diagnostic criteria of axial spondyloarthritis (SpA). Our purpose was to assess (a) whether apparent diffusion coefficient (ADC) values on diffusion-weighted imaging (DWI) differ between regions of bone marrow edema (BME) and subchondral normal-appearing bone marrow (NABM) in active sacroiliitis, (b) whether ADC values can differentiate early SpA and chronic SpA, both in the active and inactive phase, and (c) whether ADC values are related to laboratory findings.

Materials And Methods: 47 patients (24 female, 23 male, mean age: 38.

Atypical developmental venous anomaly associated with contrast enhancement and hyperperfusion in the surrounding basal ganglia.

Developmental venous anomalies (DVAs) are the most common type of cerebral vascular malformations. They are generally accepted as variants of venous development and frequently identified incidentally, particularly on contrast-enhanced MR imaging. Most of the DVAs do not affect the integrity of the surrounding parenchyma.

A rare cause of odynophagia: infected tracheal diverticulum.

Tracheal diverticulum is a relatively rare lesion. Tracheal diverticula are divided into two subgroups as congenital and acquired with different characteristics and etiologies. The majority of these anomalies is asymptomatic and found as incidental findings on radiological imaging.

Brain diffusion changes in unilateral carotid artery stenosis with non-shunt endarterectomy: Correlation with white matter lesions.

Objective: Carotid stenosis is associated with hemodynamic cerebral ischemia. Diffusion-weighted MR imaging allows for the assessment of changes related to alterations in tissue integrity. The aim of this study was to investigate (a) whether white matter lesions (WML) and apparent diffusion coefficient (ADC) values differ between ipsilateral and contralateral hemispheres, (b) whether ADC values are related to WMLs and common vascular risk factors, and (c) whether ADC values differ after carotid endarterectomy (CEA) without a shunt in patients with unilateral internal carotid artery stenosis (ICAS).

A rare manifestation of achalasia: huge esophagus causing tracheal compression and progressive dyspnea.

Achalasia is a primary esophageal motility disorder characterized by the absence of primary peristalsis and a failure of the lower esophageal sphincter to relax, resulting in a dilated esophagus. Dysphagia is the classic and most common symptom. Respiratory obstruction due to tracheal compression caused by a massively dilated esophagus is a very rare but fatal complication.

Alobar holoprosencephaly, proboscis and cyclopia in a chromosomally normal fetus: Prenatal diagnosis and fetal outcome.

Holoprosencephaly is a brain malformation that develops as a result of a defect in development of prosencephalon during early gestation. Holoprosencephaly can be diagnosed with prenatal ultrasonography and magnetic resonance imaging. We report herein a case with cyclopia and holoprosencephaly detected by prenatal ultrasonography.

Are all patients with psoriasis at increased risk for coronary artery disease?

Associations have been recently recognized between psoriasis and an increased incidence of atherosclerotic diseases. However, there are scarce data on the prevalence of coronary lesions in patients with psoriasis. The aim of this study was to identify the calcified and non-calcified atherosclerotic coronary lesions in patients with psoriasis compared to controls.

Placenta percreta resulting in incomplete spontaneous abortion in first trimester.

Placenta percreta is a rare complication potentially fatal to fetus and the mother. We present here a 41-year-old female patient who underwent curettage for incomplete abortion at 6(th) week of pregnancy. She had persistent vaginal bleeding for 2 months after the curettage, for which she was treated with hysterectomy.

Endometriosis localized to urinary bladder wall mimicking urinary bladder carcinoma.

Although endometriosis is a common disease in women of reproductive age, urinary system endometriosis is an exceedingly rare disease that may cause important clinical problems. In this paper we discussed a 42-year-old woman who had urinary bladder endometriosis misdiagnosed as urinary bladder tumor in imaging modalities. The diagnosis of endometriosis was made by histopathological examination of the operative material after partial resection of the urinary bladder.

Distal tibial osteochondroma causing fibular deformity and deep peroneal nerve entrapment neuropathy: a case report.

Osteochondromas are the most common benign bone tumors, comprising 9% of all bone tumors and 35% of benign bone tumors. They are frequently diagnosed incidentally. Osteochondromas are mostly asymptomatic, but may cause mechanical findings depending on the location and size of the tumor.

Dilatation of the Virchow-Robin spaces as an indicator of unilateral carotid artery stenosis: correlation with white matter lesions.

Background: Virchow-Robin space (VRS) dilatation is related to many pathologic conditions, mostly associated with vascular abnormalities. White matter lesions (WMLs) are commonly seen on brain magnetic resonance imaging (MRI) with advancing age and generally considered as potential markers for vascular disease.

Purpose: To investigate if asymmetric dilatation of VRSs and WMLs are associated with unilateral internal carotid artery stenosis (ICAS) and to test the relationship between dilated VRSs and common vascular risk factors.

Cerebral venous thrombosis as a rare cause of subarachnoid hemorrhage: case report and literature review.

We report a 48-year-old woman presenting with subarachnoid hemorrhage (SAH) as the first manifestation of superior sagittal sinus thrombosis. In a literature review of 73 cases, SAH associated with cerebral venous thrombosis (CVT) was usually seen at the cerebral convexities. SAH was adjacent to thrombosed venous structures; therefore, the most possible explanation seems to be the rupture of cortical veins due to extension of thrombosis.

Truncus arteriosus with persistent left superior vena cava: cardiac computed tomography findings in an unrepaired adult patient.

Truncus arteriosus (TA), a rare complex congenital cardiac disease in which systemic pulmonary and coronary circulations originate from a common vessel, develops due to failure of separation of the common trunk during embryonic life. In this case report, we discuss a 24-year-old patient with TA in whom a computed tomography angiography was performed. To the best of our knowledge, no case has been reported so far where an adult had combined left superior vena cava and pulmonary vein anomaly.

Isolated tuberculous tenosynovitis of the anterior tibial and extensor digitorum longus tendons.

Musculoskeletal system is involved in 1-5% of extrapulmonary cases of tuberculosis. Tuberculous tenosynovitis is a rare form of musculoskeletal tuberculosis. Tuberculosis of the tendon sheath in the hand has been seen in a few cases.

Localized cystic disease of the kidney: a rare cause of hypertension in a young adult.

Localized cystic disease of kidney (LCDK) is a rare, non-familial, non-progressive renal disorder that is not associated with cysts or disorders in other organs. Only a few cases have been reported in the literature. While this condition is morphologically identical to the autosomal dominant form of polycystic kidney disease, it is not inherited and is not associated with significant deterioration of renal function.

Metastasis to the male breast from squamous cell lung carcinoma.

Metastasis to breast from extra mammarian organs is quite rare with an incidence of 0.5-3%. Malignancies that most commonly metastasize to breast are lymphomas, leukemias, and malignant melanoma.

The value of diffusion-weighted magnetic resonance imaging in the differential diagnosis in diffuse bowel wall thickening.

Materials And Methods: A total of 41 patients (32 males, 9 females; mean age, 57 years) with diffuse bowel wall thickening diagnosed on computed tomography were included in this study. The magnetic resonance imaging was performed on a 1.

The role of diffusion-weighted examination in non-polyploid gallbladder malignancies: A preliminary study.

Background/aims: The aim of the present study was to investigate the diagnostic value of diffusion-weighted magnetic resonance imaging in gallbladder malignancies, which are typically diagnosed during surgery because the radiologic findings are similar to those of cholecystitis-caused diffuse thickening of the gallbladder wall.

Materials And Methods: Seven patients with gallbladder malignancies and nine patients with benign gallbladder pathology were included in this study. In one of the patients with a malignancy, a lesion was determined on the porcelain gallbladder; in another patient, acute myeloblastic leukemia had infiltrated the gallbladder, causing the diffuse wall thickening.
