OBJECTIVES: We aimed to prospectively assess the diagnostic value of apparent diffusion coefficient (ADC) measurement in the differentiation of benign and malignant mediastinal lymphadenopathies. MATERIALS AND METHODS: The study included 63 consecutive patients (28 women, 35 men; mean age 59.3 years) with 125 mediastinal lymphadenopathies. Echoplanar diffusion-weighted magnetic resonance imaging of the mediastinum was performed with b-factors of 0 and 600 mm(2)/s before mediastinoscopy and mediastinotomy, and ADC values were measured...

Congenital uterine arteriovenous malformation (AVM) is an extremely rare condition with <100 cases documented in literature. We report multiparous women presenting to us with a history of postcoital bleed. Initial Doppler ultrasonography was consistent with features suggestive of AVM. Subsequently, computed tomography (CT) angiography confirmed the diagnosis. Embolization was chosen as the treatment because of the large extension of AVM and the risk of hemorrhage during hysterectomy. The patient was discharged in a stable condition with a plan of repeat embolization in the next setting...

Asymptomatic spontaneous nephrocutaneous fistula is a rare and severe complication of chronic urolithiasis. We report a case of 56-year-old woman with a nephrocutaneous fistula (NFC) which developed from a superinfected urinoma following calyceal rupture due to an obstructing calculus in the left ureter. The patient was clinically asymptomatic and came to the emergency department for a painless left flank fluctuating mass. This urinoma was superinfected, with a delayed development of renal abscesses and perirenal phlegmon found on contrast-enhanced uro-computed tomography (CT), responsible for left renal vein thrombophlebitis and left psoas abscess...

AIM: The most ubiquitous chest diagnostic method is the chest radiograph. A common radiographic finding, quite often incidental, is the nodular pulmonary lesion. The detection of small lesions out of complex parenchymal structure is a daily clinical challenge. In this study, we investigate the efficacy of the computer-aided detection (CAD) software package SoftView™ 2.4A for bone suppression and OnGuard™ 5.2 (Riverain Technologies, Miamisburg, OH, USA) for automated detection of pulmonary nodules in chest radiographs...

Gastropleural fistula is a relatively rare complication that can be seen as a result of traumatic, nontraumatic, benign, and neoplastic etiologies. Most commonly, these are found in patients with diaphragmatic herniation or prior thoracic surgery. Aortoenteric fistulas are rare communications typically between the abdominal aorta and bowel. We present a rare case of an 88-year-old male who developed a gastropleural fistula with erosions into the wall of the descending thoracic aorta. Computed tomography (CT) is a leading modality in evaluation of suspected gastropleural or aortoenteric fistulas given the quick scan time and widespread availability...

Vaginal bleeding in the first trimester has wide differential diagnoses, the most common being a normal early intrauterine pregnancy, with other potential causes including spontaneous abortion and ectopic pregnancy. The incidence of ectopic pregnancy is approximately 2% of all reported pregnancies and is one of the leading causes of maternal mortality worldwide. Clinical signs and symptoms of ectopic pregnancy are often nonspecific. History of pelvic pain with bleeding and positive β-human chorionic gonadotropin should raise the possibility of ectopic pregnancy...

A 4-month-old infant presented with a painless swelling overlying the left angle of mandible. Ultrasound and magnetic resonance imaging (MRI) revealed a large lesion replacing the entire left parotid gland, with multiple enlarged vessels. Homogeneous enhancement of the lesion was seen on the postcontrast MRI scans. Based on the imaging features, a diagnosis of infantile hemangioendothelioma of the parotid gland was offered. This helped in avoiding any further invasive testing.

OBJECTIVES: Since 2009, the rate of nondiagnostic (ND) thyroid nodule fine-needle aspiration (FNA) has ranged from 2% to 20%. A ND result can cause further patient morbidity secondary to repeated procedures and delay in diagnosis. The use of real-time strain elastography (RTE) in determining nodule malignant risk has gained considerable focus recently. A less studied area where RTE may prove beneficial is its role in targeting areas for FNA. Our hypothesis is that FNA performed in concurrence with RTE will show a decreased rate of ND results leading to fewer repeated FNA...

Laparoscopic adjustable gastric banding (LAGB) is a bariatric procedure that is being performed with increasing frequency as an alternative management option for morbid obesity. Several common complications have been reported including gastric band slippage and associated pouch dilatation, intragastric erosion of the band, gastric wall perforation, and abscess formation. We present a case of gastropericardial fistula occurring nine years after an LAGB. There have been no previous documented cases of the complication after this procedure...

Bronchial artery aneurysm (BAA) is a rare vascular phenomenon. This review highlights a case of a BAA that was complicated by the presence of a bronchial artery to pulmonary artery (BA-PA) fistula, consequently presenting a unique challenge to management. BAAs have a strongly reported risk of rupture resulting in life-threatening hemoptysis. Embolization has thus become routine for the management such severe cases. The management of incidentally found anomalies is less obvious, but prophylactic embolization is a generally accepted practice...

The complex embryology of the anterior mediastinum makes it home to an array of primary neoplasms tied to the presence of the thyroid and thymus glands in that compartment. While the occurrence of ectopic thyroid deposits in the extramediastinal thorax has not been convincingly established, the other three "Ts" of the classic "4T" mnemonic for the differential diagnosis of an anterior mediastinal mass have occurred in the lung parenchyma, pleural space, and endobronchially as primary tumors. Finding any of the three lesions - thymoma, teratoma, or B-cell lymphoma - in the chest outside the mediastinum is very unusual, but that possibility exists...

Pulmonary artery sarcoma (PAS) is a rare and fatal disease. PAS can often be misdiagnosed as pulmonary thromboembolism. Moreover, the correct diagnosis is frequently delayed due to nonspecific signs and symptoms. The prognosis of patients with PAS is poor. We report a case of a woman with a primary PAS who was initially diagnosed with pulmonary thromboembolism.
