Spiculated masses and architectural distortions are the predominant appearances of invasive lobular carcinoma, and a computer-aided detection system correctly marked a high percentage of invasive lobular carcinoma lesions.
We present the CT findings of three cases of primary papillary serous carcinoma of the peritoneum. All patients presented with massive ascites. CT of the abdomen and pelvis showed omental caking in all patients. The parietal peritoneum of the pelvis showed diffuse enhancement with nodular thickening in all patients. No calcification was noted in the omental and parietal peritoneal masses, although psammoma bodies were present microscopically in one case. The ovaries were normal in size but showed a fine enhancing surface nodularity similar to the pelvic peritoneum. The CT findings of primary papillary serous carcinoma of the peritoneum are nonspecific, but this diagnosis should be considered when peritoneal carcinomatosis is seen on CT with normal-sized ovaries in the absence of other primary malignant neoplasms.
Male breast cancer is an uncommon disease of uncertain etiology. We describe a 66-year-old man who presented with a palpable mass in the left breast with associated nipple inversion. Mammographic images demonstrated a spiculated mass within the subareolar left breast at the palpable area of concern. Sonographic evaluation demonstrated a hypoechoic mass within the subareolar left breast at the location of the mammographic abnormality. The patient underwent an excisional biopsy and was subsequently diagnosed with high-grade invasive ductal carcinoma, the most common histologic type of carcinoma identified in men.
To the radiologist, complications of lung transplant are believed to occur along a time continuum, which is key given the nonspecific clinical and imaging findings. Pulmonary artery twisting in the immediate and early postoperative period is a known complication of transplantation, but receives relatively little attention. Early recognition is paramount due to the high morbidity and mortality of such a complication. This case highlights some imaging manifestations of the pulmonary artery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
