On MRI, there was a large, well-circumscribed lipomatous
mass deep to the gluteus maximus muscle.
Her MRI showed that her conus medullaris extended to sacral levels and she had a lipomatous
mass in that area.
hypertrophy of interatrial septum has been known since 1960's, its pathophysiology is still unclear.
variants of more typical central nervous system tumors are well known, including variants of ependymoma, glioblastoma, meningioma, among others.
Rarely, large myelolipomas can be confused with other retroperitoneal lipomatous
tumors such as liposarcoma.
We performed transesophageal echocardiography for the detection of the nature of this mass and it showed lipomatous
hypertrophy of the interatrial septum (Fig.
The entrapment of adipose tissue by an AAM may give the appearance of a benign or malignant lipomatous
tumor, and therefore, they must be considered in the differential diagnosis.
However, several hypotheses have been suggested, such as a defect in adrenergic-stimulated lipolysis, resulting in autonomy and massive proliferation of lipomatous
cells; embryologic brown fat undergoing functional sympathetic denervation; or a primary defect in brown fat mitochondrial DNA.
tumors of soft tissue: MR appearance with histological correlation.
Preoperative computed tomographic scan results suggested a mediastinal lipomatous
Recent evidence based on spermatic cord biopsies have reinforced the physiologic rationale behind MSCD by identifying dozens of microscopic (<1 mm) nerve fibres which travel within the cremasteric muscle fibres, perivasal tissues, lipomatous
tissue, and the perivascular tissues of the spermatic cord.
1) MDM2 amplification and overexpression have been most diagnostically useful in separating lipomas (MDM2 nonamplified) from well-differentiated liposarcomas/atypical lipomatous
tumors (MDM2 amplified).
