ABSTRACT Angiomyolipoma is neoplasm that derives from perivascular epithelioid cells. It is a rare mesenchymal tumor, usually found in the kidney. Extrarenal angiomyolipoma is uncommon and the most common extrarenal site is the liver. Angiomyolipoma of adrenal is extremely rare, with only four cases reported in the literature. It usually presents as incidentaloma. We report a case of a 45-year-old female patient presenting with pain abdomen, nausea, and repeated episodes of vomiting. Contrast-enhanced computed tomography (CECT) abdomen revealed heterogeneous nonenhancing hypodense fatty lesion in right adrenal gland. Biochemical investigations were negative for functioning adrenal tumor. Right adrenalectomy was done with good outcome. Diagnosis was confirmed by histopathology. The patient recovered without any complications following surgery. How to cite this article Srivastava PK, Jaiman R. Adrenal Angiomyolipoma with Gastric Outlet Obstruction.

Visceral lymphangiomatosis may occur as a benign isolated entity or as a manifestation of a systemic disorder. Multifocal involvement is exceedingly rare, with gradations ranging from extreme involvement of an isolated organ to focal involvement of multiple viscera. This case report describes the contrast-enhanced computed tomography imaging appearances of visceral lymphangiomatosis of the spleen and adrenal gland in a 31-year-old man.

Abstract Funding Acknowledgements Type of funding sources: None. Background The natural history of thoracic aortic aneurysm (TAA) is one of progressive expansion. Asymptomatic patients who do not meet criteria for repair require conservative management including ongoing aneurysm surveillance, mostly carried out by contrast-enhanced computed tomography angiography (CTA). Purpose To prospectively compare image quality and reliability of a prototype non-contrast, self-navigated 3D whole-heart magnetic resonance angiography (MRA) with contrast-enhanced computed tomography angiography (CTA) for sizing of thoracic aortic aneurysm (TAA). Methods Self-navigated 3D whole-heart 1.5 T MRA was performed in 20 patients (aged 67 ± 8.6 years, 75% male) for sizing of TAA; a subgroup of 18 (90%) patients underwent additional contrast-enhanced CTA on the same day. Subjective image quality was scored according to a 4-point Likert scale and ratings between observers were compared by Cohen’s Kappa statistics. Continuous MRA and CTA measurements were analyzed with regression and Bland-Altman analysis. Results Overall subjective image quality as rated by two observers was 1 [interquartile range (IQR) 1-2] for self-navigated MRA and 1.5 [IQR 1-2] for CTA (p = 0.717). For MRA a perfect inter-observer agreement was found for presence of artefacts and subjective image sharpness (κ=1). Subjective signal inhomogeneity correlated highly with objectively quantified inhomogeneity of the blood pool signal (r = 0.78-0.824, all p <0.0001). Maximum diameters of TAA as measured by self-navigated MRA and CTA showed excellent correlation (r = 0.997, p < 0.0001) without significant inter-method bias (bias -0.0278, lower and upper limit of agreement -0.74 and 0.68, p = 0.749). Inter- and intraobserver correlation of aortic aneurysm as measured by MRA was excellent (r = 0.963 and 0.967, respectively) without significant bias (all p ≤ 0.05). Conclusion Self-navigated 3D whole-heart MRA enables reliable contrast- and radiation free aortic dilation surveillance without significant difference to standardized CTA while providing predictable acquisition time and by offering excellent image quality.
