Multiple Hepatic Hydatid Cysts in a Patient with Ischemic Heart Disease: A Case Report

In many parts of the world, a specific type of tapeworm can cause a hidden and slow-growing problem inside the human body. This parasite, known as Echinococcus, lives its adult life in the intestines of dogs and other canines. When eggs from these worms are accidentally swallowed by a person—often through contaminated food or water—they hatch and travel through the bloodstream to settle in organs, most frequently the liver. There, they grow into fluid-filled sacs called cysts. These cysts can remain silent for years, but as they expand, they press against healthy tissue, causing pain, swelling, and sometimes severe complications if they burst. While doctors in certain regions are familiar with this condition, known as hydatid disease, treating it becomes a delicate balancing act when the patient has other serious health issues. The heart, in particular, demands careful attention; if a patient has ischemic heart disease, where the heart muscle does not receive enough blood due to narrowed arteries, the stress of major surgery can become life-threatening. The challenge lies in removing the parasitic growth without triggering a cardiac crisis.

This story comes from a medical report detailing the treatment of a fifty-year-old man who faced exactly this double burden. He arrived at a hospital at Anwer Khan Modern Medical College complaining of a dull, aching pain in the upper right side of his abdomen that had been worsening for four months. The pain radiated toward his back and grew worse after eating, accompanied by a loss of appetite and a drop in weight. Although he appeared unwell and somewhat pale, his vital signs were stable. A closer look at his blood revealed signs of infection and inflammation, including a high number of white blood cells and a specific type of cell called an eosinophil, which often rises when the body fights a parasite. His blood also showed a mild anemia and a slightly slower-than-normal clotting time.

When doctors examined his abdomen, they felt a firm, tender swelling in the upper right area, and an ultrasound confirmed their suspicions: his liver was enlarged and filled with large, complex cysts. A more detailed scan, a computed tomography image, showed that these were not simple bubbles but multilayered structures with internal walls, resembling a wheel with spokes. The largest of these cysts was massive, measuring 14.9 by 12.0 centimeters, occupying a significant portion of the right side of the liver. The patient also had a history of ischemic heart disease, a condition diagnosed years earlier that meant his heart was vulnerable to the strain of surgery.

The medical team knew they had to act, but the path forward required a precise strategy. They could not simply rush into an operation, as the risk of a heart attack during the procedure was high. Instead, they began by treating the patient with a medication called albendazole, which helps kill the parasite and shrink the cysts, preparing the body for the next step. They also paused his heart medication, specifically a blood thinner, to reduce the risk of bleeding during the operation. Once the patient was stabilized, the surgeons performed a major abdominal procedure. They made a long incision down the center of the abdomen and carefully packed the area with protective cloths to prevent the cyst fluid from spreading to other parts of the body. Upon opening the liver, they found the cysts were firmly attached to the stomach and the liver surface. They carefully removed the cysts, washed the empty spaces inside the liver and the abdominal cavity with a strong salt solution to kill any remaining parasite eggs, and then stitched the liver back up, leaving drains to remove excess fluid.

The tissue removed from the liver was examined under a microscope, revealing the classic signs of the disease: the normal liver tissue had been replaced by scar tissue and inflammatory cells, with no signs of cancer. The patient recovered well from the surgery. In the weeks that followed, he did not experience a return of the infection or any major heart complications. This case illustrates that even when a patient faces two difficult health challenges at once, a coordinated effort between different specialists can lead to a successful outcome. By combining drug therapy with careful surgical planning and close monitoring of the heart, the team was able to remove the parasitic cysts while keeping the patient safe. The report serves as a reminder that in complex medical situations, the key to success often lies in treating the whole person, not just the disease, and ensuring that every step of the plan accounts for the unique risks the patient carries.
