Adrenal lipoma & Adrenal Adenoma

Adrenal Lipoma (P1)

Composed mainly of fat, it appears as a low-density area on non-contrast CT (below -30 HU), similar to fat tissue.

• It may contain small amounts of soft-tissue density, representing fibrous or other non-fat components.
• No significant enhancement or only mild enhancement on contrast-enhanced scans.

Adrenal Adenoma (P2)

Shows a density of 10-30 HU on non-contrast CT, resembling soft tissue.

• Some lipid-rich adenomas may show lower densities but usually not below -30 HU.
• Demonstrates noticeable enhancement in the arterial and venous phases, but the enhancement is less intense than adrenal cortical carcinoma.

Image description: Frontal chest radiograph (image 1) shows increased attenuation of the soft tissues of the chest wall (arrow). The appearance is more conspicuous on contrast-enhanced chest CT (image 2), which demonstrates enhancement along fascial planes and serosal surfaces.

Teaching point: Diffuse serosal and soft tissue enhancement is a rare imaging phenomenon observed in infants following cardiac catheterization. It has been described in a small proportion of neonates after contrast administration, particularly with higher total contrast volumes or greater contrast dose normalized to body surface area. On radiographs and CT, contrast within the soft tissues and serosal surfaces results in increased attenuation that may exceed that of solid organs and can mimic other processes, including intraperitoneal free air. In this context, the distribution and recent procedural history distinguish this finding from true pathology.

Image description: Frontal (image 1) and lateral (image 2) abdominal radiographs show an amorphous calcification (arrow) in the left suprarenal region. Longitudinal ultrasound (image 3) shows a hyperechoic structure in the left suprarenal space with posterior acoustic shadowing. No associated soft tissue mass is identified.

Teaching point: Adrenal hemorrhage occurs most commonly in neonates because the adrenal glands are relatively large, highly vascular, and vulnerable to venous congestion. Predisposing factors include birth trauma, perinatal stress, hypoxia, sepsis, and coagulation abnormalities. Remote hemorrhage typically heals with coarse or amorphous suprarenal calcification without a residual soft tissue mass. In contrast, adrenal neuroblastoma more often demonstrates punctate or stippled calcifications within a persistent soft tissue mass that may enlarge over time.

Image description: Axial contrast-enhanced CT images in soft tissue (image 1) and bone (image 2) windows, as well as coronal (image 3) CT, show an ovarian teratoma characterized by fat density (arrowhead), fluid density, and calcifications suggestive of bone or teeth (arrow). Ovarian teratomas are the most common ovarian neoplasms and are usually benign. While malignant transformation can occur, imaging cannot reliably differentiate benign and malignant tumors.

Image description: Post-contrast fat-suppressed T1-weighted MRI shows heterogeneous enhancement of the mass with non-enhancing cystic & fatty elements. The right kidney (yellow) is compressed without demonstrating a true “claw” sign. The prior CT image showed calcifications (orange) & fat (blue) in the mass. The constellation of CT & MRI findings is most typical of a retroperitoneal teratoma. #FridayQuizDay
