Sometimes life comes at our patients fast. Consider Kristen, a young lady who sought care at Cleveland Clinic’s Center for Spine Health a few years ago, when she was 28. Life was quite good for Kristen: She had married Nick in 2009, and they shared dreams of having a family and building a fulfilling life together. Her zest for life was palpable.  Suddenly, however, her world began to collapse. First she had a miscarriage eight weeks into her first pregnancy. Then she had a skin lesion removed that proved to be malignant melanoma. Throughout all this, she was experiencing escalating neck pain, which she largely ignored because of all her other stressors. As the pain progressively worsened, she developed problems with balance and coordination. MRI of her spine revealed yet another problem — an intramedullary cervical spine tumor (i.e., within the substance of the spinal cord; Figure 1).

This newest, and perhaps most challenging, of her problems forced Kristen to confront her mortality. Her expectations of a long and productive personal and family life had already been threatened by the miscarriage and her melanoma diagnosis. While it seemed as though her melanoma was cured by surgery, she was now confronted with this new diagnosis and the many risks associated with removing a tumor from the main corridor ‒ the spinal cord ‒ connecting her brain with the environment in which she lived.

The Inevitable Questions

Kristen voiced a litany of concerns and questions: “Holy cow! This tumor is inside my spinal cord?” “I have sooo many other problems.” “Why me?” “Where did this come from?” “How did it get so big with so few symptoms?” “Is it malignant?” “Can I be cured?” “How in the world do you take this out without paralyzing me?”

The Spine Specialist Responds

“Kristen, these are all great questions. In fact, they are very similar to those asked by nearly all patients who have this problem. Let’s start by addressing ‘Why me?’ Simply stated, bad luck ‒ particularly considering your miscarriage and your diagnosis of a malignant skin tumor. No one knows why or how these tumors begin or grow. The good news is that your spinal cord tumor is likely a benign tumor. However, it is situated in a very bad location: the cervical spinal cord. Since it is benign, it grew slowly ‒ very slowly. Likely, your spinal cord adapted to the gradually expanding tumor over time. That’s why you had so few symptoms before this large tumor was diagnosed. We must emphasize that this tumor is not malignant. How do we know? Well, if it were malignant, a tumor of this size would have grown rapidly and not allowed the spinal cord to adapt gradually. If it were malignant, Kristen, you would be paralyzed.

“Kristen, as few as two to three decades ago, neurosurgeons did not operate on patients with spinal cord tumors of this kind (intramedullary). Then, a few surgeons began successfully removing such tumors. Today these tumors can be resected (removed), often with cure. These operations are very risky, however. They involve an incision in the spinal cord followed by tumor removal. The ultimate success is related to multiple factors, the most important of which may be tumor type. Your tumor is likely benign and resectable, but it’s not without substantial risk, including the possibility of developing weakness in your arms or legs, loss of sensation over your body, or loss of bowel or bladder function. You could become dependent on a ventilator or even have complete paralysis, like that experienced by Christopher Reeve. Other risks include medical complications associated with any surgery, such as heart attack, stroke, blood clots in the legs or lungs, wound infection, the need for additional surgery or even death, to name just a few. The tumor type dictates its resectability and the potential for cure.”

Case Continued: Successful Surgery, Rocky Postop

Kristen absorbed the information and sought counsel from family and friends. After much discussion, she decided to have surgery. Two intraoperative photographs of the surgical bed after resection are shown in Figure 2.

The surgery was uneventful, but Kristen had a challenging postoperative course. As is often the case with intramedullary cervical spine tumors, she was substantially worse neurologically after the surgery. In fact, most patients do not achieve a level of function that is comparable or superior to their preoperative level. Most postoperative patients, like Kristen, experience a moderate to significant decline in function. Kristen lost the ability to walk normally for several weeks, but she gradually improved over six months to her normal baseline level of function. Postoperative MRI demonstrated complete resection of the tumor, without evidence of recurrence at two-year follow-up (Figure 3). The X-rays in Figure 4 show spinal implants required to stabilize the spine after surgery.

 Perspective on the Risk Two Years Out

In spite of Kristen’s string of bad luck, she prevailed. Six months after surgery, she achieved a neurological outcome that was near normal ‒ a truly remarkable recovery. During this time frame, however, a second pregnancy ended in another miscarriage. Regardless, Kristen and Nick demonstrated courage and fortitude. She recently gave birth to her daughter, a wonderful reward for all her trials and tribulations.

“It’s sobering to think that 25 years ago, I likely would have been relegated to a treatment course that ultimately would have led to a fatal outcome,” Kristen says. “Surgery can be curative, and I am glad to have chosen the surgical route. It simply has made it all worthwhile.”
