ABSTRACT
Although endovascular aneurysm repair (EVAR) in the abdominal aorta has reduced the perioperative mortality when compared with open repair, the need for reintervention after complications such as endoleak may be presented in up to 20% of the cases. Type II endoleak from branch vessels is often benign but can potentially be associated with progressive abdominal aortic aneurysm growth and sac expansion. We present a rare case of a patient who presented with sac expansion and psoas hematoma due to Type II endoleak from "unusual" collaterals of IMA and was treated successfully with endoleak microembolization and percutaneous decompression of the hematoma.
ABSTRACT
INTRODUCTION: Solitary necrotic nodule of the liver is a rare lesion, with similar radiologic findings to those of hepatic metastases or other liver masses. CASE PRESENTATION: We here report a case of a 30-year-old male with hepatic solitary necrotic nodule discovered after an episode of acute abdominal pain and high grade fever. Routine laboratory data revealed leukocytosis and abnormal liver function. The imaging features of the lesion suggested malignancy or liver adenoma. The patient underwent surgical resection of segments V and VI. Histology was compatible with solitary necrotic nodule and localized vein thrombosis at the periphery. CONCLUSION: Solitary necrotic nodule of the liver is a benign lesion which can mimic liver malignancies. Abdominal imaging and liver biopsy are often equivocal. In such circumstances liver resection is mandatory to exclude HCC or other malignant liver lesions.
