Gideon Asen Files Medical Malpractice Lawsuit Over Delayed Cancer Diagnosis

Gideon Asen has filed a medical malpractice and wrongful death lawsuit on behalf of the Estate of Theresa Campbell, alleging that medical providers failed to properly investigate abnormal imaging findings that were later determined to be aggressive uterine cancer.

The complaint was filed in Androscoggin County Superior Court by Richard Campbell, Theresa’s husband and the Personal Representative of her estate. The defendants named in the lawsuit are Central Maine Healthcare, X-Ray Professional Association, and Dr. Tad Renvyle, a diagnostic radiologist.

According to the complaint, Theresa Campbell, a 65-year-old post-menopausal woman, underwent a CT scan in April 2023 after reporting blood-tinged urine and flank pain. The CT scan showed an enlarged uterus and recommended further evaluation with ultrasound.

The lawsuit alleges that the ultrasound that followed was abnormal and limited, but that Dr. Renvyle reviewed 39 images in less than two minutes before concluding that Theresa had a harmless fibroid and recommending no further workup. The complaint states that the report failed to disclose the limitations of the study, failed to recommend additional imaging, and gave Theresa’s providers false reassurance that the finding was benign.

Theresa trusted her doctors to give her the careful attention every patient deserves. Instead, an ultrasound ordered to assess her condition was reviewed in less than two minutes, labeled reassuring, and the diagnostic process stopped while an aggressive cancer spread. This case is about accountability — not just for one provider’s failures, but for a healthcare system that allowed speed and false reassurance to override caution and patient safety.

The complaint alleges that, over the following months, Theresa experienced worsening symptoms, including abdominal pain, dizziness, low blood pressure, progressive back pain, and significant unintended weight loss. In October 2023, another CT scan revealed a large pelvic mass that had significantly increased in size and was concerning for cancer. Theresa underwent surgery in November 2023, which revealed advanced metastatic uterine carcinosarcoma. The complaint alleges the cancer had spread extensively, including to both ovaries and fallopian tubes, the sigmoid colon, and the lungs. Theresa later transitioned to hospice care and died at home on January 5, 2024, at age 65. She left behind her husband of 48 years, three children, and four grandchildren.

Gideon Asen filed the case to seek accountability for Theresa Campbell’s death and for the harm her family alleges was caused by a breakdown in safe, reasonable medical care.
