Abstract:We report a unique case of chronic contained thoraco-abdominal aneurysm rupture presenting as a Grynfeltt lumbar hernia. A 79-year-old man presented with backpain and a bluish swelling in the left lumbar region in the presence of a non tender aortic aneurysm. CT scan confirmed contained rupture of a type IV thoraco-abdominal aortic aneurysm. The peri-aortic haematoma protruded through the lumbar wall causing a Grynfeltt lumbar hernia. The aneurysm was replaced through a thoraco-phreno-lumbotomy. The patient su… Show more
“…The psoas muscle and vertebral body resist the pressure of retroperitoneal hemorrhage [6] as was the case in our patient. In addition, a small aneurysmal tear, fibrosis and organized thrombus are considered to be the mechanism for chronic AAA rupture [7]. CTA is a very sensitive diagnostic imag-ing for complete and sovereign diagnosis of chronic AAA retroperitoneal rupture.…”
We present a patient having had the lower back pain for 4 months, which had been recognized and treated as lumbar ischialgia but which was eventually diagnosed to be chronic infrarenal abdominal aortic aneurysm rupture by computed tomography angiography. The surgical intervention was successful and the patient was discharged from hospital after 6 days without any clinical complications. Preoperative imaging by computed tomography angiography of ruptured abdominal aortic aneurysm is highly sensitive for detection of several specific signs for rupture. This condition leads to urgent vascular surgery.

“…DU has been found sufficient for initial detection of CCRs, but can fall short when a rupture is too small or posterior to detect. 3 A partially encapsulated retroperitoneal hematoma, periaortic hypoechoic or anechoic regions are initial indicators detected by gray-scale imaging. 16 Application of color flow and spectral Doppler settings has been found useful in detection of leaks or extravasations with appropriate scale and gain settings.…”

“…Compared with acute ruptures, which generally manifest as sudden flank/abdominal pain and hypotension, chronic contained ruptures (CCR) are subtle and may go undetected for months or in some cases years. 1–3 Symptomatology of a CCR has been documented as chronic lower back pain, intermittent abdominal pain in the left lower quadrant (LQ), groin pain, weight loss, and lower extremity weakness or neuropathy. 2–8 Although temporarily encapsulated, a CCR is a ruptured aneurysm which may progress to a free rupture, warranting immediate surgical intervention upon diagnosis.…”
Introduction
Chronic containment of a ruptured abdominal aortic aneurysm (AAA) is a rare clinical phenomenon that is often accompanied by abstract symptomatology, delayed diagnosis, and treatment. We describe a case of chronic contained rupture (CCR) in a hemodynamically stable and asymptomatic patient detected by duplex ultrasound (DU).
Patient Description
A 71-year-old white male presented to our medical facility to establish cardiac care for newly diagnosed pleural effusion and bilateral lower extremity edema. Physical examination revealed prominent abdominal aortic pulsations. An abdominal DU was ordered to evaluate for an AAA.
Methods
An abdominal DU examination was performed utilizing a Philips iU22 xMATRIX Ultrasound System equipped with a C5–1 MHz PureWave transducer. The aorta, common iliac and external iliac arteries were evaluated with gray scale, color, and spectral Doppler applications.
Imaging Results
The DU confirmed the presence of a 5.6 cm × 5.7 cm infrarenal AAA. The lumen was noted to have irregularities and multiple avascular hypoechoic lesions that were reproducible in multiple imaging planes. Computed tomography (CT) confirmed the presence of the 4.8-cm aneurysm accompanied by a 5.6 cm × 4.0 cm multi-lobular fluid collection extending into the mesentery. Active extravasations were not visualized during contrast administration; nevertheless, the appearance of the irregularity was suspicious of aneurysm leak resulting in evolving hematoma. The CCR was treated with a bifurcated intraluminal stent graft.
Conclusion
This case describes an extremely rare rupture complication that may be present during routine evaluation of the abdominal aorta. Because of its rarity in case presentation, standardized protocol for detection and sonographic presentation remain undocumented.
“…In our case, neurological evaluation was normal. Paraparesis [10], paraplegia [11], low back pain [14], and lumbar hernia [15] were reported in the literature.…”
Chronic-contained aortic aneurysm rupture with vertebral erosion is a rare entity with fatal complications. Multidetector computed tomography (CT) angiography is an important diagnostic method for the evaluation of the aortic aneurysms, their complications, and also the relationship between aneurysm and branching vessels and adjacent structures. We present the multidetector CT angiography findings of a 62-year-old patient with chronic-contained thoracoabdominal aortic aneurysm rupture causing severe vertebral body erosion.
