Imaging of renal transplant: utility and spectrum of diagnostic findings.
Current problems in diagnostic radiology
2011; 40 (3): 127-139
Several noninvasive imaging techniques have been developed and improved over recent years that facilitate detection of both vascular and nonvascular postoperative complications as well as diagnosis of diseases related to the transplanted organ itself. In this article, we present a multi-modality review of the spectrum of pathology related to renal transplantation.

Sclerosing angiomatoid nodular transformation of the spleen: CT, MR, PET, and Tc-99m-sulfur colloid SPECT CT findings with gross and histopathological correlation
2010; 35 (6): 683-689
Sclerosing angiomatoid nodular transformation (SANT) is a benign, proliferative vascular lesion affecting the spleen. Few reports detailing the cross sectional and PET appearance of this lesion are available, and the lesion's behavior with ⁹⁹(m)Tc-sulfur colloid scintigraphy is previously unreported. Sclerosing nodular transformation of the spleen shows increased tracer accumulation on positron emission tomography, and a central scar-like appearance with an enhancing capsule and radiating septae on CT and MR studies that reflects the gross and histopathological features of the lesion may be visible. An understanding of this pathological finding may allow prospective recognition of the sclerosing nodular transformation of the spleen on cross sectional imaging studies.

Posterior parahepatic cyst as an incidental finding-review of 40 cases
2010; 65 (1): 26-33
To describe the characteristic imaging features of the incidental, isolated posterior parahepatic cyst.Out of 150 patients previously identified on computed tomography (CT) to have an incidental, isolated posterior parahepatic cyst, 40 patients had lesions that were large enough to be assessed for enhancement on CT and/or magnetic resonance imaging (MRI) and had at least 1 year of imaging follow-up. All available CT, MRI, and 2- [(18)F]-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET) examinations for these 40 patients were reviewed, and the lesions were assessed for size, attenuation, and location relative to the spine and right kidney.For the 40 patients reviewed, all parahepatic lesions were shown to be cysts by absence of identifiable enhancement on CT or MRI. Cysts ranged in size from 3mm to 2.5cm. Hounsfield unit (HU) measurements ranged from 12HU to 83HU. In the transverse plane, all cysts were located lateral to the lateral margin of the right kidney. In the craniocaudal dimension, all cysts were at or above the level of the right kidney, and all were located between the T11-12 and L1-2 vertebral levels. All cysts were stable on follow-up imaging with a mean duration of follow-up of 41 months.Isolated, indolent posterior parahepatic cysts have a characteristic appearance and location and demonstrate benign behaviour with stability on follow-up imaging. These cysts should be considered in the differential diagnosis for isolated parahepatic lesions, and the imaging features described here aid in the distinction of these cysts from other entities such as metastatic disease.

Imaging manifestations of Meckel's diverticulum
AMERICAN JOURNAL OF ROENTGENOLOGY
2007; 189 (1): 81-88
Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract, found in 2% of the population in autopsy studies. Most patients remain asymptomatic during their lifetime. Complications of Meckel's diverticulum are reported to occur in approximately 4-40% of patients and include inflammation (diverticulitis), hemorrhage, intussusception, small-bowel obstruction, stone formation, and neoplasm. The purpose of this article is to familiarize the radiologist with the current imaging of Meckel's diverticulum and its presenting complications. The spectrum of diagnostic findings on various imaging techniques will be reviewed.Meckel's diverticulum and its complications are a serious health problem. Familiarity of the radiologist with the appearance of this pathologic entity enables an accurate diagnosis in emergent settings.
