The radiation protection practices implemented in the radiology departments of tertiary hospitals in southeastern Nigeria have a significant impact on the safety of patients, healthcare professionals, and the general public. However, there is a lack of comprehensive understanding regarding adherence to standard radiation protection protocols in these departments.

Crossed fused renal ectopia is a rare congenital malformation, with an estimated incidence of 1 in 7'500 live births. It occurs more frequently in males and represents the second most common renal fusion anomaly after the horseshoe kidney. Renal scintigraphy with [⁹⁹ᵐTc]Tc-DMSA remains the most reliable method for confirming the diagnosis and assessing renal function.

NaF PET/CT demonstrates significantly higher sensitivity, specificity, and overall diagnostic accuracy than 99mTc bone scintigraphy for detecting skeletal metastases across malignancies. Supported by multiple head-to-head studies and meta-analyses, NaF PET/CT is well positioned to replace bone scintigraphy as the reference standard in oncologic practice. Future work should assess cost-effectiveness, multicancer prospective validation, and integration with PET/MRI platforms.

This case underscores the importance of considering ectopic thyroid tissue within the anterior mediastinum in the differential diagnosis of anterior mediastinal masses, which more commonly include thymic tumors, germ cell tumors, and lymphomas.

Struma ovarii is a form of mature monodermal teratoma, a rare germ cell tumor containing more than 50% thyroid tissue. Its transformation into a malignant tumor is rare. NIFTP (non-invasive follicular thyroid neoplasm with papillary nuclear features) is an entity characterized by a completely encapsulated follicular proliferation with papillary nuclear features, but without invasion or high-risk criteria. It has an excellent prognosis when located in the thyroid gland. Its presence in the struma ovarii makes its prognosis uncertain. We report a case of ovarian NIFTP treated with complementary iodine-131 isotope therapy.
