Ultrasound features - ✅ Hepatic Abscess 🎯 * Complex cystic hepatic lesion with thick, wall and internal debris. * Posterior acoustic enhancement ± septations/loculations. * Peripheral hyperemia on Doppler, with absent/minimal internal vascularity. * Gas with dirty shadowing, when present, strongly supports abscess. * Adjacent inflammatory change may be present. Differentials * Amoebic abscess: sonographically overlaps considerably; clinical/serological correlation is needed. * Necrotic metastasis/HCC: consider if there is a vascularized solid component, mural nodule, multiple lesions, known malignancy or tumour thrombus. * Infected cyst: usually a pre-existing cyst with new wall thickening/debris. * Hydatid cyst: daughter cysts, membranes or calcification favour the diagnosis. * Cystic neoplasm: thick vascularized septa or mural nodules favour neoplasm. * Hematoma: trauma/intervention history and lack of inflammatory hyperemia favour this diagnosis.
