OPINION BY SENIOR JUDGE BARBIERI, December 29, 1988:
Jacqueline Johnson (Claimant) petitions for review of the order of the Workmen's Compensation Appeal Board (Board) which denied her petition for rehearing. We reverse and remand.
On October 5, 1984, Claimant suffered a work-related lumbrosacral sprain while in the employ of Carter Footwear, Inc. (Employer) and received benefits for total disability pursuant to a notice of compensation payable. On July 1, 1985, Employer filed a petition for termination relying on the testimony of Doctor Joseph R. Sgarlat who opined that Claimant had recovered from her low back sprain and that all Claimant's x-rays, CAT-scan and EMG studies were normal and he could find no evidence of herniated disk, nerve damage, or muscle atrophy. Claimant presented the testimony of Doctor Lewis L. Rogers who stated that although objective studies of Claimant were negative, she continued to suffer from a soft tissue injury. The referee accepted Doctor Sgarlat's testimony and granted Employer's petition on June 8, 1987.
Claimant then petitioned the Board for a rehearing in order to present newly discovered medical evidence of Claimant's condition. Specifically, Claimant underwent a myelogram followed by a CAT-scan on July 7, *406 1987, which, according to the report of Doctor John C. Querci, shows that Claimant suffers from a herniated disk at the L5 region. The Board denied Claimant's request, citing Taylor v. Workmen's Compensation Appeal Board (Doylestown Township), 108 Pa. Commonwealth Ct. 642, 530 A.2d 975 (1987). But Taylor does not involve a petition for rehearing.
The grant or denial of a petition for rehearing is within the discretion of the Board. Douglas v. Workmen's Compensation Appeal Board (Bethlehem Mines Co.), 32 Pa. Commonwealth Ct. 156, 377 A.2d 1300 (1977). It was formerly settled that the Board does not have the power to remand cases to a referee simply to permit the presentation of additional medical evidence which was available at the time of the initial hearing. Genovese v. Workmen's Compensation Appeal Board (National Record Mart, Inc.), 69 Pa. Commonwealth Ct. 176, 450 A.2d 325 (1982).
However, in Jones v. Workmen's Compensation Appeal Board (First Pennsylvania Bank), 76 Pa. Commonwealth Ct. 345, 463 A.2d 1266 (1983), we held that where vital evidence not available at the time of the referee's decision was discovered by surgery thereafter, it was an abuse of the Board's discretion to deny a request for rehearing. We stated:
Here, the claimant sought to introduce after-discovered evidence of DeQuervain's Disease and ulnar nerve inflammation, which is relevant to the issue of whether or not she continued to be disabled. Mindful that in termination petition cases, an employer must prove conclusively the termination of a claimant's disability, Certainteed Corp. v. Workmen's Compensation Appeal Board, 57 Pa. Commonwealth Ct. 646, 648, 426 A.2d 1282 (1981), we conclude that the board abused its discretion by ignoring Mrs. Jones' request. *407 Jones, 76 Pa. Commonwealth Ct. at 347-348, 463 A.2d at 1268.
In the present case, as in Jones, it was only through the performance of a surgical procedure, specifically a myelogram, that the true cause of Claimant's disability was revealed. No one knew at the time of the referee's decision on June 8, 1987 that Claimant was suffering from a herniated disk for the simple reason that a herniated disk is a soft tissue injury that does not appear on an x-ray. (Report of Doctor John C. Querci dated 9/25/ 87; R.R. 4a). Indeed, x-rays of Claimant's spine taken on July 15, 1987, after the referee's hearing and myelogram appear perfectly normal. (R.R. 6a). It was only after the myelogram was performed on Claimant on July 7, 1987, during which a contrast medium was injected into Claimant's spinal column, that the herniated disk was discovered. (Report of Doctor Edward Kelly dated July 7, 1987; R.R. 7a). Consistent with Jones is the fact that no such surgical procedure was done prior to the referee's hearing.
We note that in Cudo v. Hallstead Foundry, Inc., 517 Pa. 553, 539 A.2d 792 (1988), our Supreme Court recently reversed this Court for incorrectly imposing on the Board the judicial standard that a new trial on the basis of after discovered evidence may only be granted if the evidence could not have been obtained at trial by reasonable diligence. The Court concluded that rehearings should be granted "in the interests of justice" in order to effectuate the humanitarian purposes of The Pennsylvania Workmen's Compensation Act (Act).[1]Cudo, 517 Pa. at 557, 539 A.2d at 794.
The Chief Justice stated in Cudo:
The strict view of the dissent, which would permit a claimant only one opportunity to meet his *408 or her substantial burden irrespective of the dictates of justice, is not appropriate in this area of jurisprudence.
Cudo, 517 Pa. at 560, 539 A.2d at 795 (NIX, C.J., concurring). The Supreme Court's reasoning in Cudo bolsters our decision in Jones and supports our view that the interests of justice dictate a rehearing. We conclude the Board abused its discretion in denying Claimant's petition for rehearing, and accordingly, we reverse and remand with instructions that the requested rehearing be granted.

ORDER
NOW, December 29, 1988, the order of the Workmen's Compensation Appeal Board at No. A-93888, dated May 13, 1988, is reversed, and the case is remanded to the Board with instructions that a hearing be held before a referee to consider after discovered evidence described in this opinion. Jurisdiction relinquished.
DISSENTING OPINION BY JUDGE PALLADINO:
I respectfully dissent. The decision of the Board in denying Claimant a rehearing should be affirmed.
Whether to grant a rehearing is within the discretion of the Board. The medical evidence presented by Claimant at the original hearing was not equivocal; it was just not accepted by the referee. There was a full and complete record before the referee. Claimant chose her medical expert and that expert testified that Claimant had a soft tissue injury. Two years after the referee reached his decision, Claimant consulted another doctor who ordered a test, not previously performed, which indicated a soft tissue injury.
The Board determined that the referee had made his decision upon a complete record. I agree. Additional medical evidence, even if not cumulative, need not require *409 a rehearing. There is no indication here that a full and complete medical inquiry was not made at the time of the first hearing. It is not necessary that every conceivable medical test which might aid in diagnosis be performed for a medical record to be complete. The Board did not abuse its discretion in declining to grant a rehearing to allow additional medical evidence "discovered" two years after the original hearing.
The majority's reliance on Jones v. Workmen's Compensation Appeal Board, 76 Pa. Commonwealth Ct. 345, 463 A.2d 1266 (1983), is misplaced. In Jones, the evidence was indeed after-discovered medical evidence. It was discovered as a result of a surgical procedure done to correct a medical problem. A myelogram is not done to correct medical problems. A myelogram is a diagnostic test. It is termed surgery only because it requires injection of a dye, making it an invasive procedure. The test could have been ordered by Claimant's physician. He chose not to utilize it.
The majority opinion also cites the Pennsylvania Supreme Court decision in Cudo v. Hallstead Foundry, Inc., 517 Pa. 553, 539 A.2d 792 (1988), as support for its conclusion that the Board abused its discretion in denying a rehearing. The Supreme Court in Cudo, 517 Pa. at 558, 539 A.2d at 794 (quoting Greeby v. Philadelphia Asbestos Co., 120 Pa. Superior Ct. 9, 12, 181 A.2d 452, 453 (1935)), stated:
[I]t is held that the court's duty does not extend to sending the record back for an opportunity to furnish cumulative evidence to strengthen a weak case, as the board's finding is binding on it; but it does not hold that so long as the record is within the grasp of the board it may not order a rehearing for further testimony to be taken.
Based on this test, the court in Cudo held that this court had erred in reversing the Board's grant of a *410 rehearing because this court had applied the judicial standard for granting rehearings. The Supreme Court discounted "due diligence," a part of the judicial standard, as a factor to be considered when reviewing the Board's grant of a rehearing. It did not foreclose the Board from considering it as a factor.
The Supreme Court in Cudo emphasized that the Board was correct in ordering a new hearing because the Board had determined that the medical evidence before it was equivocal and in light of the employee's death from a heart attack while at work, a full and complete medical inquiry was required, in the interests of justice, to assess the merits of the claim.
Because factually we are not met with either a Jones or a Cudo case, we should not disturb the Board's exercise of its discretion.
