OBJECTIVE To describe the multimodality imaging features, metastatic pattern and clinical outcome in adult extraskeletal Ewing sarcoma (EES). METHODS In this institutional review board-approved, health insurance portability and accountability act-compliant retrospective study, we included 26 patients (17 females and 9 males; mean age, 36 years; range,(More)
OBJECTIVE To describe the multidetector CT (MDCT) features and metastatic pattern of succinate dehydrogenase (SDH)-deficient gastrointestinal stromal tumours (GISTs). METHODS In this institutional review board-approved, Health Insurance Portability and Accountability Act-compliant study, we retrospectively identified 34 patients (20 females; mean age, 34(More)
OBJECTIVE This study aimed to describe magnetic resonance imaging (MRI) features of extremity liposarcoma (LPS) subtypes, correlating with histopathology and clinical outcomes. METHODS In this retrospective study, we included 125 patients (80 men, 45 women; mean age, 53 years) with extremity LPS [23 atypical lipomatous tumor (ALT), 9 dedifferentiated(More)
Small bowel obstruction is a common condition encountered by the radiologist in the emergency department. Though intestinal adhesions and obstructed hernias are the most common causes of acute small bowel obstruction, a variety of uncommon and rare conditions can cause acute and subacute bowel obstruction. Imaging plays a key role in the workup of bowel(More)
OBJECTIVE To describe the pattern of dedifferentiated liposarcoma (DDLPS) metastases and to analyze their predictors and outcome. MATERIALS AND METHODS In this retrospective study, we reviewed the imaging and clinical records of all consenting patients with histopathology-confirmed DDLPS seen from 2000 through 2012. The predictive value of clinical and(More)
To define the various CT densities of nonlipomatous component of dedifferentiated liposarcoma (DDLPS) and to determine if the rate of growth varies with density. This study identified 60 patients with DDPLS (38 men, 22 women; mean age at diagnosis 59 years, range, 35–82 years) who had one or more resections. CT scan immediately before the surgical resection(More)
OBJECTIVE To describe metastatic pattern of uterine leiomyosarcomas (ULMS) and correlate it with clinical and histopathologic parameters. METHODS We included 113 women (mean age, 53 years; range, 29 to 72 years) with histopathology-confirmed ULMS from 2000 to 2012. Distribution of metastases was noted from imaging by two radiologists in consensus.(More)
Malignant esophageal neoplasms other than squamous cell carcinoma and adenocarcinoma are uncommon and include endocrine tumors, lymphoid malignancies, melanoma, malignant stromal tumors, and secondary tumors (metastases). Imaging, though not diagnostic in many cases, helps in selecting the appropriate treatment strategy by determining the anatomic extent of(More)
Over the past few decades, the survival of esophageal cancer patients has improved owing to early detection and advances in multimodality treatment strategies. Imaging plays an important role in every step in the management of esophageal cancer, including diagnosis, staging, assessment of treatment response, and post-treatment surveillance. In this article,(More)
To evaluate MRI features of response of primary extremity liposarcoma (LPS) to neoadjuvant radiation therapy (RT) with histopathologic correlation. In this IRB-approved study including 125 patients with extremity LPS treated with neoadjuvant RT from 2000 to 2013, MRI of the primary tumour in 18 patients (5 pleomorphic LPS, 13 myxoid LPS) before and after RT(More)
