Patient's CT abdomen was done that showed a relatively encapsulated, heterogeneously and moderately enhancing soft-tissue density mass (right:5.9 x 5.3 x 6.9 cm and left:3.8 x 3.9 x 4.6 cm) bilaterally in suprarenal area with internal necrotic and cystic areas (Figure 1(b)). 24 hr urinary metanephrines estimation was 450 mmol/mol creatinine (N:30-211 mmol/mol creatinine). Patient's 24 hr urinary vanillylmandelic acid estimation (VMA) was 137.86 micromol/day (N:2.02-77.91 micromol/day). Histopathological examination of adrenal mass showed tumor cells arranged in mixed trabecular and nested pattern with marked nuclear pleomorphism and increased mitotic rate (Figure 1(a)).
