Purpose. The aim of this study was to present the computed tomography (CT) findings of bezoars that cause obstruction in the small bowel and to emphasize that some CT findings can be considered specific to some bezoar types. Materials and Methods. The records of 39 patients who underwent preoperative abdominal CT and subsequent operation with a diagnosis of intestinal obstruction due to bezoars were retrospectively analyzed. Results. In total, 56 bezoars were surgically removed from 39 patients. Bezoars were most commonly located in the jejunum (n = 26/56, 46.4%). Sixteen (41.0%) patients had multiple bezoar locations in the gastrointestinal tract. Common CT findings in all patients were a mottled gas pattern and a focal ovoid or round intraluminal mass with regular margins and a heterogeneous internal structure. Furthermore, some CT findings were determined to be specific to bezoars caused by persimmons. Conclusions. Preoperative CT is valuable in patients admitted with signs of intestinal obstruction in geographic regions with a high bezoar prevalence. We believe that the correct diagnosis of bezoars and the identification of their number and location provide a great advantage for all physicians and surgeons. In addition, some types of bezoars have unique CT findings, and we believe that these findings may help to establish a diagnosis.

Central venous catheterisation allows delivery of medications, intravenous fluids, parenteral nutrition, haemodialysis and monitoring of haemodynamic variables. Various complications may occur during and after the procedure. However, the complete guidewire retention has rarely been reported. In this report, we have presented a complete guidewire retention as a result of inadvertent catheter insertion. After 17 months of the first operation performed upon the diagnosis of Fourniers gangrene, the patient was admitted to the cardiology polyclinic with a recurrent chest pain. Echocardiography showed a wire-shaped foreign body within the right part of the heart, and a fluoroscopic examination showed a guidewire reaching from the superior vena cava to the right external iliac vein. In retrospect, the wire was already visible on the postoperative chest x-rays and CT taken while the patient was still in intensive care unit, but its presence was overlooked at that time. The guidewire was retrieved completely during a surgery.

Idiopathic granulomatous mastitis (IGM) is a rare inflammatory, noncaseating, chronic granulomatous benign disease. The etiology of IGM is still unknown. It is postulated to be an autoimmune localized response. The use of a course of oral steroids provides an important regression of breast mass and skin lesions. Topical corticosteroids are used to treat many skin diseases, but no study is available on the sole use of topical steroids for treating IGM. Eleven women with IGM were treated with topical steroid and evaluated using mammography, ultrasonography, and dynamic MRI. At the end of the 12th week, patients were clinically and radiologically evaluated for the regression of breast and skin lesions. Pre‐ and post‐treatment time‐intensity curve patterns (TICs) were also compared. During the topical steroid treatment, the inflammation signs in the affected breast had markedly disappeared, the fistulas had become inactive, and the fistula orifices and/or skin erosions had closed in nine patients. The median follow‐up period was 17 months (range: 12–48 months). Recurrence was observed in two patients (2/11) at 5 and 8 months, which were treated again topically. The inflammatory findings of the breast skin completely resolved after 8 weeks of treatment, and no side effects or steroid‐related complications occurred. In the pretreatment period, TICs from enhancing areas showed a Type 1 pattern in three cases, a Type 2 pattern in five cases, and a Type 3 pattern in three cases. After topical steroid treatment, TIC was not changed only in one patient (Type 2). Type 1 patterns were determined in seven cases and Type 2 patterns in two cases. In addition, in two patients, TICs were not determined due to complete healing. Our MRI findings showed that topical steroid therapy may be useful because it affects mammary parenchyma as well as mammary skin. Further studies with a greater number of patients are needed to determine the topical steroid therapy dosing and duration, and to better understand the efficacy for treating IGM.

Summary Background Congenital dermoid cysts are very rare, constituting less than 1% of intracranial tumors. Spontaneous rupture of dermoid tumor is a potentially serious complication that can lead to meningitis, seizures, cerebral ischemia and hydrocephalus. Occasionally, dermoid tumors are incidentally discovered on computed tomography (CT) of the brain or magnetic resonance imaging (MRI) following unrelated clinical complaints. They are also discovered during radiologic investigations of unexplained headaches, seizures, and rarely olfactory delusions. Case Report In this report we describe a patient complaining of vertigo caused by spontaneous rupture of dermoid cyst, preoperatively diagnosed by CT and MRI. Cranial CT revealed a dense fatty lesion adjacent to the posterolateral parasellar region on the left with multiple small, dense fat droplets scattered in the subarachnoid space corresponding to a dermoid cyst rupture. Cranial MRI sections revealed a lesion with mixed-signal-intensity and multiple hyperintense droplets scattered through the cerebellar surface on the left. No enhancement was found on axial T1-weighted MRI after intravenous Gadolinium administration. Diffusion weighted image (DWI) and apparent diffusion coefficient map studies exhibited explicit restricted diffusion. Discussion Many studies and literature case reports concerning the rupture of dermoid cyst have been reported. However, multimodal imaging of this rare pathology in the same patient is uncommon. Although dermoid cysts are pathognomonic in appearance on a CT examination, the MRI is also of value in helping to understand the effect of extension and pressure of the mass. DWI is also important for support of the diagnosis and patient follow-up.

BACKGROUND This study was conducted to evaluate the initial and mid-term patency rates of chronic total femoropopliteal artery (FPA) occlusions treated by subintimal angioplasty (SIA) and stenting. METHODS From March 2010 to February 2013, 74 patients were included in the study. Seventy two patients with total occlusion of the FPA and good distal runoff (2 or 3 patent vessels) were treated with percutaneous SIA and stenting. All patients had severe claudication or critical limb ischemia. In all cases, the procedure was performed with a contralateral approach. Follow-up was done at 6 months with clinical evaluation and color-Doppler. If it was necessary, peripheric angiography was performed. RESULTS Immediate technical success was achieved in 72 (97%) patients. Two (3%) distal embolizations, 2 (3%) groin hematomas, 1 (1%) femoral pseudoaneurysm and 1 (1%) rupture of the junction-external iliac-superficial femoral artery occurred. All of the complications were treated successfully. Total occlusion in 1 patient and critical occlusion in 3 patients were showed at the 6th month. Patency rate at the sixth month was 94% with a stent length of 13.4 ± 8.2 cm. CONCLUSIONS Percutaneous SIA and stenting for chronic total of the FPA occlusion showed good initial and mid-term patency rates, with few periprocedural complications.

A 64-year-old woman was admitted to our clinic with progressive dyspnea (New York Heart Association class III) and fatigue for 3 months. Dysphagia for solids more than for liquids was present for 3 years. Transthoracic echocardiography demonstrated extrinsic left atrial compression and impaired left atrial filling because of the compression (Fig. 1). Esophagoscopy revealed a submucosal mass in the distal esophagus. Computed tomography of the chest (Fig. 2) and magnetic resonance imaging of the mediastinum revealed the extra cardiac mass located in the wall of the distal esophagus, compressing the left atrium. The patient was referred for surgical treatment. Enucleation of the mass was performed by thoracotomy. Histophatology confirmed the diagnosis of leiomyoma. The postoperative evolution was uneventful.

A 15-year-old female patient with progressive pulsatile exophthalmos caused by intraorbital encephalocele was evaluated with computed tomography (CT) and magnetic resonance imaging (MRI) in our clinic. She had no history of trauma or reconstructive surgery. When she was a little girl, she had undergone surgery for congenital glaucoma on the right eye. On the three-dimensional image of CT, a hypoplasic bone defect was observed in the greater wing of the right sphenoid bone. MRI and CT scan showed herniation through this defect of the arachnoid membrane and protruded cerebral tissue into the right orbita. Intraorbital encephalocele is an important entity that can cause pulsatile exophthalmos and blindness.

INTRODUCTION Gastric volvulus is a rare surgical emergency with a high mortality rate that requires urgent surgical management. PRESENTATION OF CASE A 19-year-old male and 51-year-old female patient underwent emergency surgery with a prediagnosis of acute abdomen syndrome, and a 60-year-old female patient underwent elective surgery due to diaphragmatic hernia. Abdominal exploration revealed gastric volvulus together with perforation in received emergency surgery patients, and a mesenteroaxial gastric volvulus due to diaphragmatic defect in third patient. DISCUSSION Gastric volvulus is classified into four subgroups depending on the mechanism of development, and organoaxial form is the most common type of gastric volvulus. The most challenging step in diagnosing gastric volvulus is the consideration of this diagnosis. CONCLUSION Preoperative diagnosis is often difficult, and its management involves surgical correction of the pathology followed by institution of resuscitative treatment.

Median arcuate ligament syndrome is an anatomic and clinical entity characterized by dynamic compression of the proximal celiac artery by the median arcuate ligament, which leads to postprandial epigastric pain, vomiting, and weight loss. These symptoms are usually nonspecific and are easily misdiagnosed as functional dyspepsia, peptic ulcer disease, or gastropathy. In this report, we presented a 72-year-old male patient with celiac artery compression syndrome causing recurrent abdominal pain associated with gastric ulcer and iron deficiency anemia. This association is relatively uncommon and therefore not well determined. In addition, we reported the CT angiography findings and three-dimensional reconstructions of this rare case.
