A 91-year old woman was referred to our hospital for evaluation of a palpable mass in the left hemiabdomen. A marked anemia was found on admission. Imaging revealed an inhomogeneous mass of the left adrenal gland with a diameter of 19 cm. Due to a lack of perfusion in contrast enhanced ultrasound and the clear delineation to neighbouring organs on CT scan, an adrenal hemorrhage was diagnosed. A further fall of hemoglobin level prompted a resection of the mass. The mass consisted of a fibrous wall surrounding hematomas of different age. A small rest of the otherwise normal adrenal gland was found adjacent to the wall. The patient fully recovered. The patient had no underlying cause for the hemorrhage such as trauma, tumor or any coagulopathy including the intake of anticoagulants. Hence, we describe a rare case of spontaneous unilateral adrenal hemorrhage in an elderly woman that was successfully treated by surgery.
Adrenal hemorrhage is a rare disease predominantly including bilateral involvement . It typically occurs in underlying conditions such as sepsis [2,3], heparin-induced thrombocytopenia , antiphospholipid antibody syndrome , trauma , or adrenal tumors . Moreover, it has been described in neonates , pregnant women , and patients after surgery [10,11]. We here present a 91-year old woman with a massive left-lateral idiopathic adrenal hemorrhage.
A 91-year old woman was referred to our hospital for further evaluation of a palpable mass in the left hemiabdomen discovered by her general practitioner after complaining of light abdominal pain in this region. The patient suffered from dementia and was immobilized. Her medication included an ACE-inhibitor and haloperidol but no anticoagulants. No trauma or other conspicuous event was reported by her nursing home. A normal blood pressure had been documented during the weeks prior to admission. Physical examination revealed a pale skin and a bulging, rigid, and fixed, but indolent tumor in the left hemiabdomen.
The physical examination was unremarkable otherwise. Abnormal laboratory findings were hemoglobin (8.6 g/dL) and creatinine (2.0 mg/dL), platelet count and coagulation tests were normal. Transabdominal ultrasound revealed an inhomogeneous, sharply delineated mass of 17 x 19 cm in diameter in the left hemiabdomen (Figure 1). After contrast injection (5 mL Sonovue®), the lesion did not enhance throughout the entire study (Figure 2). Due to the elevated creatinine, the CT scan was performed without contrast agent (Figure 3). A drop of hemoglobin to 6.8 g/dl on the third day after admission prompted an operation despite the patient's frailty.
The mass was successfully removed without complications (Figure 4) and the patient was discharged one week later after full recovery to her prior status. The removed mass (17 cm in diameter) consisted of a fibrous capsule and hematomas of different ages (Figure 5). A residual of the adrenal gland was found adjacent to the capsule (Figure 6).
Adrenal hemorrhage is a rare finding, particularly when unilateral, without underlying disease or trauma, and with normal coagulation. The precise mechanisms leading to adrenal hemorrhage are uncertain. In nontraumatic cases evidence has implicated a limited venous drain (e.g. by vein spasm or thrombosis) in contrast to the rich arterial supply of the gland . As indicated by the huge capsule and the hematomas of different age within, the hemorrhage in our case was recurrent. Hemorrhage was obviously not controlled under observation leading to a significant drop in hemoglobin. Hence, in face of the patient's clinical status, we deem the decision for operation justified. Mortality of adrenal hemorrhage is estimated 15% . Death can result from rupture of the capsule [13,14] or from the underlying condition. Adrenal insufficiency does not occur in unilateral hemorrhage but can be fatal in bilateral cases .
In our patient, primary diagnosis was made by ultrasound including a contrast enhanced study. Distinguishing an adrenal hemorrhage from a neoplasm by imaging can be difficult . Contrast enhanced ultrasound (CEUS) is a valuable tool to visualize real time vascularisation and perfusion even in small adrenal masses . Despite the inhomogeneous iso-hypoechogenic aspect in the baseline ultrasound, CEUS did not show any enhancement of the mass at any time. This pattern has earlier been described for adrenal hemorrhage and (in this size) strongly argues against a solid lesion . To further delineate the anatomical attribution we performed a CT scan without contrast agent. The neighbouring organs were not involved. However, this test did not help to further distinguish the masses origin.
There is some disagreement over the term "hemorrhagic adrenal pseudocyst" in literature. While some authors claim this entity to be a (pseudo-)cystic degeneration of a primary adrenal neoplasm or a vascular neoplasm/malformation others hypothesize a primary hemorrhage into the adrenal gland with secondary wall formation [19,20]. The mass in our patient was surrounded by an intact fibrous wall. This may also be described as "adrenal pseudocyst". Adjacent to the wall was a small rest of the otherwise unremarkable gland. Since adrenal hemorrhage can result from a neoplasm such as pheochromocytoma  plasma free metanephrines should be tested before operation. Due to the urgency we failed to do so. An alternative procedure to surgery in ongoing hemorrhage can also be the embolisation of the bleeding adrenal artery . Nevertheless, our patient fully recovered indicating that resection of a hemorrhagic adrenal gland can be successful in very old patients.
