A 52-year-old woman was admitted to our hospital with thrombophlebitis of the internal jugular vein. Abdominal ultrasonography demonstrated a high echogenic mass measuring 4.5 cm in diameter in the liver, and abdominal CT revealed another liver tumor and an isodensity mass in the spleen. Abdominal MRI and angiography were performed and we presumed the tumors to be two hepatic angiomyolipoma and a splenic hamartoma. As an abdominal CT 21 months later revealed that all tumors were growing, these tomors were surgically resected. The histological diagnoses were hepatic angiomyolipoma and splenic hamartoma.

Background: A right adrenal gland may present in the form of adreno-hepatic fusion (AHF), in which the adrenal cells are interspersed among the hepatocytes without septation. This rare, naturally-occurring phenomenon may be associated with preoperative misdiagnosis. We present two cases of adrenal tumor in patients with AHF that were misdiagnosed, despite thorough preoperative work-ups.

A 55-year-old man with tuberous sclerosis complex (TSC) was diagnosed with left renal angiomyolipoma (AML), a group of perivascular epithelioid cell tumors called PEComas. He had received the mTOR inhibitor everolimus, which resulted in a complete response. However, a left renal mass relapsed in two years, followed by the occurrence of a hepatic mass five months later.

Aims: The hepatic perivascular epithelioid cell tumour (PEComa), including angiomyolipoma, exhibits diverse morphology and clinical behaviour; however, its prognostic features remain undefined. This study aimed to investigate its histological features and prognostic factors.
Methods And Results: In total, 132 patients were included.

Ultrasound (US) is a widely used technique for liver disease but has limitations in distinguishing tumors. This study evaluates the clinical efficacy of fluctuational imaging (FLI), a new US method that detects the fluttering sign in liver tumors. We conducted a prospective exploratory study with 120 participants diagnosed with liver tumors through histopathology or standard imaging.

Hepatic angiomyolipoma (HAML) is an uncommon primary liver tumor with limited reported cases in the literature. It is composed of varying amounts of fat, smooth muscle, and blood vessels, typically non-malignant proliferation. It usually presents diagnostic challenges due to diverse imaging characteristics.
