Unusual Aggressive Breast Cancer: Metastatic Malignant Phyllodes Tumor by Adam Singer et al. |
Published: 2013 Feb Issue: 7(2) :: Pages: 24-37
| Abstract: For the year of 2012, it has been estimated that breast cancer will account for the greatest number of newly diagnosed cancers and the second highest proportion of cancer related deaths among women. Breast cancer, while often lumped together as one disease, represents a diverse group of malignancies with different imaging findings, histological appearances and behavior. While most invasive primary breast cancers are epithelial derived adenocarcinomas, rare neoplasms such as the phyllodes tumor may arise from mesenchymal tissue. Compared to the breast adenocarcinoma, the phyllodes tumor tends to affect a younger population, follows a different clinical course, is associated with different imaging and histological findings and is managed distinctively. There may be difficulty in differentiating the phyllodes tumor from a large fibroadenoma, but the mammographer plays a key role in reviewing the clinical and imaging data in order to arrive at the correct diagnosis. Early diagnosis with proper surgical management can often cure non-metastatic phyllodes tumors. However, in rare cases where metastasis occurs, prognosis tends to be poor. This report describes the presentation, imaging findings and management of a metastatic malignant phyllodes tumor.

Rare case of urinary bladder agenesis - Multislice CT abdomen imaging by Venkatraman Indiran et al. |
Published: 2013 Feb Issue: 7(2) :: Pages: 44-49
| Abstract: Complete agenesis of urinary bladder is an extremely rare anomaly with only a few live cases reported so far. In most of the instances death occurs early as it may be incompatible with life. Here we report a case of adolescent female with urinary bladder and unilateral renal agenesis, who presented with a rather unusual presentation of incontinence, for a computed tomography (CT) examination. Other congenital abnormalities visualised in the CT abdomen are also discussed.

Ischemic Bowel: Uncommon Imaging Findings in a Case of Cocaine Enteropathy by Wesley Angel et al. |
Published: 2013 Feb Issue: 7(2) :: Pages: 38-43
| Abstract: While the clinical findings of cocaine-induced enteropathy from mesenteric ischemia are fairly well understood, there is a paucity of imaging description and detail in the literature that describes these findings. Imaging characteristics of cocaine-induced mesenteric ischemia on CT examination include bowel edema, mucosal enhancement, venous engorgement, mesenteric free fluid, and dilatation of the small bowel lumen. A thorough history, physical examination, and laboratory testing are critical for the diagnosis and prompt surgical intervention may be necessary. We present a case of cocaine-induced mesenteric ischemia in a 49 year old male which resolved within 24 hours of supportive therapy.

Anomalous Morphology of an Ectopic Tooth in the Maxillary Sinus on Three-Dimensional Computed Tomography Images by Yee-Tak Alta Lai et al. |
Published: 2013 Feb Issue: 7(2) :: Pages: 11-16
| Abstract: We describe a case of an incidentally-diagnosed ectopic tooth showing anomalous morphology in the maxillary antrum, using three-dimensional reconstruction of computed tomography images of the tooth obtained by multi-detector computed tomography.

Spontaneous intramural esophageal hematoma (IEH) secondary to anticoagulation and/or thrombolysis therapy in the setting of a pulmonary embolism: a case report by Melina Hong et al. |
Published: 2013 Feb Issue: 7(2) :: Pages: 1-10
| Abstract: Intramural esophageal hematoma is part of a spectrum of esophageal injuries. Vomiting and straining, endoscopic procedures and bleeding disorders are the most common predisposing factors. However, it can also be an unusual complication of anticoagulation and/or thrombolysis therapy. The most common symptoms are retrosternal chest pain, dysphagia and hematemesis. Computed tomography is the modality of choice and treatment is medically conservative with the cessation of Warfarin and thrombolysis use. When anticoagulation and/or thrombolysis therapy is necessary, periodic reassessment for symptoms of intramural esophageal hematoma may be helpful for early identification and management. We described one case of intramural esophageal hematoma possibly resulting from anticoagulation and/or thrombolysis therapy in the setting of pulmonary embolism.

Characterization of Malignant Thrombus in an Invasive Thymoma with Intravascular Growth by Sevtap Gümüstas et al. |
Published: 2013 Feb Issue: 7(2) :: Pages: 17-23
| Abstract: We report an unusual case of an invasive thymoma with a thrombus in the right atrium and describe the radiological findings consistent with the malignant nature of the thrombus. The thrombus showed significant enhancement on computerized tomography images similar to the tumoral mass. On magnetic resonance imaging, both the tumor and the thrombus have heterogeneously high signal intensities on T2-weighted images. On diffusion-weighted images they both exhibit high signal intensity and low apparent diffusion coefficient (ADC) values which support the malignant nature of the thrombus and the mass.
