Isolated hepatic tuberculoma: A case report and review of the literature

Table 2 Timeline of imaging findings and lesion characteristics

Date	Modality	Lesion size	Imaging features
January 17, 2022	MRCP	Approximately 28 mm	Abnormal signal focus in the caudate lobe, associated with bile duct stenosis and proximal biliary dilation. Enlarged hilar lymph nodes
January 18, 2022	Abdominal CT	Approximately 20 mm	Subtle hypodense lesion in the caudate lobe with mild enhancement. Enlarged lymph nodes in the hepatic hilum and retroperitoneum with ring enhancement
January 20, 2022	Abdominal MRI	Approximately 26 mm	Irregular, mixed-signal foci in the caudate lobe with mildly prolonged T1/T2 signals, diffusion restriction, and ring enhancement. Markedly enlarged and enhanced lymph nodes in the hepatic hilum
January 24, 2022	Abdominal ultrasound	50.5 mm × 25.5 mm	Hypoechoic mass in liver segment I (S1), with internal hyperechoic changes, seen encircling the portal vein

MRI: Magnetic resonance imaging; CT: Computed tomography; MRCP: Magnetic resonance cholangiopancreatography.
