case_images: MRI scans. (A) and (C) show the cervical lesion and the left pelvic wall metastatic lymph node before treatment, respectively; (B) and (D) show the cervix and the left pelvic wall lymph node after treatment, respectively.

case_images: Enhanced magnetic resonance imaging (MRI) of the entire abdomen revealed a thickened soft tissue mass occupying space in the cervix (approximately 4.6*3.8*5.3 cm) (Figure 1A), which was consistent with changes associated with cervical cancer. A nodule (approximately 3.1*2.5 cm) was present near the left pelvic wall (Figure 1C), which was considered to be a metastatic lymph node. TC regimen chemotherapy were given. The MRI was repeated at the end of treatment, and the lesion had regressed satisfactorily (Figure 1B and D).

case_images: The lesion was hypermetabolic (maximum and mean standardized uptake values [SUVmax and SUVmean] were 7.2 and 4.5, respectively), and a tumor lesion was not excluded (Figure 2).

case_images: The mass invaded the left middle and upper turbinates and the left ethmoid sinus and was poorly demarcated from the nasal septum (Figure 3).
case_images: (A) (HE staining, x10) and (B) (HE staining, x5) are the first postoperative images revealing a Schneiderian papilloma; (C) (HE staining, x10) and (D) (HE staining, x20) are the second postoperative images revealing a Schneiderian papilloma that exhibited papilloma-like hyperplasia.

case_images: Postoperative pathological examination of the neoplastic mass in the left maxillary sinus revealed a Schneiderian papilloma (Figure 4A and B). Schneiderian papilloma with squamous epithelium that exhibited papilloma-like hyperplasia (Figure 4C and D). Some areas exhibited an inverted growth pattern.
case_images: The changes, treatment, and timeline of SCCA assessment throughout the course of the disease. The quantitative results for SCCA shown in red are higher than normal (SCCA normal range 0-1.8ng/ mL). The patient underwent sinus tumor resection on October 12, 2020, and an enlarged sinus tumor resection on June 18, 2021.

case_images: In the subsequent routine follow-up examination, the SCCA levels had gradually elevated again starting two months after the surgery and were consistently higher than normal (Figure 5). The patient has been in good condition, and the SCCA level has remained normal (Figure 5).

case_images: Therefore, an MRI of the sinuses was performed on May 27, 2021, that revealed a nodular soft tissue shadow (approximately 1.9*1.7*1.3 cm) in the left nasal cavity and the inner wall of the maxillary sinus in the previously resected area (Figure 6).
