Extra-Adrenal Myelolipoma Presenting as Efferent Limb Obstruction

الملخص EN

Myelolipomas are rare benign lesions composed of mature adipose tissue and immature hematopoetic cells.

The adrenal gland is the most common location for these lesions, but cases of extra-adrenal myelolipomas have been described.

The predominant location for extra-adrenal myelolipomas is the retroperitoneum, and very few reported cases describe these lesions in the peritoneal cavity.

Typically these lesions are incidental findings and asymptomatic, but occasionally can present with symptoms secondary to mass effect.

We present the case of a 72 year old man presenting with a gastric outlet obstruction secondary to an epigastric mass.

The mass was resected and pathology was consistent with myelolipoma.

This case illustrates an atypical location and presentation of a myelolipoma.

These are rare tumors with only 5 intra-abdominal myelolipomas reported in the literature.

This article is a review of the surgical literature and a discussion on myelolipomas.

Knowledge of these rare entities can help ensure proper management of these patients, which may include early surgical intervention.
