Mimickers of neoplasm on abdominal and pelvic CT

Abdominal Imaging, 2014
The radiologist can encounter benign significant imaging findings on computed tomography that can be incorrectly interpreted as neoplasm. The authors review several benign findings and demonstrate several methods to differentiate these findings from more sinister pathology.It is imperative for the radiologist to be cognizant of and how to correctly ...

ABDOMINAL MUCINOUS CYSTIC NEOPLASM IN A MALE CHILD

Pediatric and Developmental Pathology, 2006
Mucinous cystic neoplasms (MCNs) make up a morphologic family of similar appearing tumors arising in the ovary and various extraovarian sites, including the pancreas, hepatobiliary tract, paratesticular soft tissues, and mesentery. Other than the uncommon mucinous cystadenoma of the ovary presenting in adolescence, MCNs are rarely seen by the pediatric

MR angiography in abdominal neoplasms

European Radiology, 1994
The role of magnetic resonance angiography (MRA) in the evaluation of vascular involvement was studied in 55 patients with abdominal neoplasms. A 2-D time-of-flight (TOF) technique was used in 18 patients. All patients underwent CT and MR examinations before MRA.

CT features of abdominal plasma cell neoplasms

European Radiology, 2005
The aim of this study was to describe the CT features of abdominal plasma cell neoplasms. We reviewed CT imaging findings in 11 patients (seven men, four women; mean age 62 years) with plasma cell neoplasms and abdominal involvement. Helical CT of the entire abdomen and pelvis was performed following intravenous administration of contrast material ...

Abdominal Lymphangioma Masquerading as a Pancreatic Cystic Neoplasm

Journal of Clinical Gastroenterology, 1995
Lymphangiomas are congenital abnormalities of the lymphatics that occur predominantly in the head and neck, most often in children. We present an unusual case of a middle-aged man who had a large septated cystic lesion adherent to the pancreas that could not be differentiated from a pancreatic cystic neoplasm despite analysis by ultrasound, computed ...

USE OF THORACICOABDOMINAL INCISION FOR UPPER ABDOMINAL NEOPLASMS

Archives of Surgery, 1952
REMOVAL neoplasms of the upper abdomen frequently requires extirpation of multiple organs. Although most lesions of the region can be adequately attacked through a direct abdominal incision, certain bulky neoplasms present problems in removal because of their size and the involvement of more than one structure.

Abdominal Neuroendocrine Neoplasm with Misplaced Exocytosis

Ultrastructural Pathology, 1993
A 22-year-old man presented with epigastric fullness and tenderness. A 14-cm mass that was adherent to the sigmoid colon was removed surgically. The tumor exhibited ultrastructural evidence of neuroendocrine differentiation but defied precise classification.

Simultaneous abdominal aortic aneurysm repair and nephrectomy for neoplasm

The American Journal of Surgery, 1995
Abdominal aortic aneurysm and renal neoplasm are occasionally discovered concurrently. Simultaneous operative therapy may be an effective alternate management strategy to a staged procedure.The medical records of 10 consecutive patients undergoing abdominal aortic aneurysm repair and nephrectomy for renal neoplasm were reviewed. Data collected included

Upper Abdominal Neoplasms: An Introduction and Selected References

Ultrastructural Pathology, 1991
The organs in the upper half of the abdominal cavity can give rise to a highly heterogeneous collection of neoplasms that encompasses a broad spectrum of clinical features, light microscopic appearances, immunostaining properties, and fine structure. Because of the anatomic proximity of the viscera in this region, the differential diagnosis of an upper
