Cerebral Metastasis in a Fatal Adrenocortical Carcinoma: A Rare Presentation of an Aggressive Tumor

Abstract

Adrenocortical carcinomas (ACCs) are rare, aggressive tumors often discovered incidentally. These malignancies may present with abnormal hormone secretion or, as in some cases, as non-functioning masses causing discomfort. We present a case of brain metastasis in a patient with a giant ACC. A 50-year-old man presented with headache and dizziness. A computed tomography (CT) scan showed an intracranial lesion within the parenchyma measuring 73*60*46 mm with left internal temporal involvement, abundant vasogenic edema and compressing the lateral left ventricle. Further imaging investigations identified a large necrotic tissue mass measuring 15 cm, located on both sides of the right diaphragmatic dome, in the middle posterior region. Hormonal workup was conducted and excluded a functional adrenal tumor. A CT-guided biopsy was performed, confirming ACC. Despite medical management, the patient's condition deteriorated rapidly, with the cerebral metastasis proving fatal. This case underscores the challenges posed by advanced ACC, particularly when associated with atypical metastatic sites. Giant ACC, though rare, presents significant diagnostic and therapeutic challenges. Surgical excision with appropriate oncologic management can lead to favorable outcomes. This report contributes to the limited literature on cerebral metastases in ACC, aiming to enhance awareness among clinicians managing this rare entity.
