Adrenocortical carcinoma (ACC) is a rare malignancy, especially in children. The overall incidence is approximately 2 cases per million per year.[1] In children, the incidence is 0.3 cases per million per year, except in southern Brazil where the incidence is 3.4–4.2 cases per million per year.[2] We describe a giant nonfunctioning metastasized ACC in a 6-year-old girl who presented with a history of increasing abdominal girth incidentally noticed by her mother since 1 week. Ultrasound abdomen showed a large right suprarenal tumor with calcifications and necrosis. Empty left renal fossa and compensatory enlarged right kidney were seen. Computed tomography (CT) scan revealed a large heterogenously enhancing right suprarenal mass with calcification and necrosis with pulmonary metastasis. Histopathology report from the right suprarenal mass revealed an ACC. With a stage IV disease, the patient died after 2 months from diagnosis.

Magnetic resonance imaging has been shown to be a useful tool in the evaluation of oral malignancies because of direct visualization of lesions due to high soft tissue contrast and multiplanar capability. However, small oral cavity tumours pose an imaging challenge due to apposed mucosal surfaces of oral cavity, metallic denture artefacts and submucosal fibrosis. The purpose of this pictorial essay is to show the benefits of pre and post contrast MRI sequences using various dynamic manoeuvres that serve as key sequences in the evaluation of various small oral (buccal mucosa and tongue as well as hard/soft palate) lesions for studying their extent as well as their true anatomic relationship.

Highlights Glomangiopericytoma is rare sinonasal disease with very good prognosis after surgical excision. Prognosis is very good after surgical excision. As most nasal tumors our case was also an accidental diagnosis following endoscopic sinus surgery. and complete clearance was suspicious. Patent was referred for adjuvant radiation. Revision surgery was done and wide clearance was established. Patient was saved from radiation.
