12. At least one non-CNS, measurable target lesion as per RECIST 1.1 documented at conventional imaging, performed within 30 days prior to Day 0.
13. Participant agrees not to participate in another interventional study while participating in the present study, defined as signing the informed consent form (ICF) until completion of the last study visit.
14. Negative serum pregnancy tests in female patients of childbearing potential at screening and confirmation of negative pregnancy test result from urine within24 hours prior to receiving investigational product. Female patients of non-child-bearing potential must provide evidence by fulfilling one of the following criteria at screening:

1. Post-menopausal defined as aged more than 50 years and amenorrheic for at least 12 months following cessation of all exogenous hormonal treatments.
2. Women under 50 years old would be consider postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and with luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels in the post-menopausal range for the institution.
3. Documentation of irreversible surgical sterilization by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy but not tubal ligation
4. For all participants, consent to practice double-barrier contraception until a minimum of 42 days after 89Zr-girentuximab administration.

Exclusion Criteria:

1. Exposure to murine or chimeric antibodies within the last 5 years.
2. Previous administration of any radionuclide within 10 half-lives (of the radionuclide) prior to the intended administration of 89Zr-girentuximab(i.e., within 10 half-lives of Day0).
3. Exposure to any CAIX targeting compound (diagnostic/therapeutic) in the last 3 months
4. Serious non-malignant disease (e.g. psychiatric, infectious, autoimmune or metabolic) that may interfere with the objectives of the study or with the safety or compliance of the subject, as judged by the Investigator.
5. Any clinically significant abnormalities detected during screening laboratory tests or physical exam that in the opinion of the Investigator would adversely affect the participants ability to participate in the study. Principal Investigator to assess patient suitability for inclusion based on pathology and tumor type.
6. Mental impairment that may compromise the ability to give Informed Consent and comply with the requirements of the study.
7. Exposure to any antineoplastic treatment within 14 days from the date of planned administration of 89Zr-girentuximab(i.e. within 14 days of Day 0).
8. Women who are pregnant or breastfeeding.
9. Known allergy, hypersensitivity, or intolerance to girentuximab, DFO (desferrioxamine),or any of the components of the investigationalagent.10.Renal insufficiency with glomerular filtration rate (GFR) ≤ 45 millilitres/min/1.73m2
10. Vulnerable patients (e.g. being in detention).
