Mielolipoma adrenal gigante: revisión a propósito de un caso

Tratamiento laparoscópico transperitoneal de mielolipoma suprarrenal

“…La localización suele ser intraadrenal, aunque se han descrito sitios extraadrenales (pulmón, mediastino, hígado, estómago, leptomeninges y, especialmente, la región presacra). 5,6 El origen de los mielolipomas suprarrenales es incierto; sin embargo, se han planteado hipótesis como: a) metaplasia de células corticales suprarrenales o estromales pluripotenciales provocadas por estrés crónico, degeneración y aumento de la concentración de cortisol (estados de hiperactividad), b) hematopoyesis extramedular en situaciones patológicas, c) embolismo de células de la médula ósea y d) restos embriológicos de la médula ósea. 3,7 Algunos autores sugieren que el exceso de secreción de hormonas adrenocorticotrópicas durante un miento actual.…”

Giant Adrenal Myelolipoma as a Cause of Chronic Abdominal Pain: Abdominal Pain due to Giant Myelolipoma

“…They can also be found in the presacral location (48-50%), thorax, retroperitoneum, pelvis, stomach and perianal [5]. The majority of myelolipomas are asymptomatic and are found incidentally in imaging tests being located within the so-called "incidentalomas", which are found when performing imaging studies not intended for evaluation or by surgical finding [6]. The use of high-resolution imaging has led to an increased rate of incidental detection of unilateral adrenal masses, which most commonly are benign non-functioning adrenal adenomas.…”

“…When they present symptomatology, abdominal pain is the most frequent, however, they can also cause symptoms due to mechanical compression as hematuria or renovascular hypertension. They can be complicated by rupture and necrosis, with retroperitoneal hemorrhage (Wunderlich's syndrome) [2,6]. In the last 15 years it has increased more than ten times its diagnosis, due to the use of high resolution imaging techniques such as ultrasonography and computerized axial tomography.…”
