The technetium-99m methylene diphosphonate (99mTc-MDP) whole-body bone scan along with single-photon emission computed tomography (SPECT/CT) can detect challenging soft tissue uptake patterns. We present a case of a 67-year-old female in whom the 99mTc-MDP scan, performed 3 hours after injection, revealed abnormal soft tissue uptake in the right thoracic region. No functioning right kidney was seen in the right lumbar region. Hybrid SPECT/CT revealed an ectopic right kidney in the subdiaphragmatic location, accompanied by gut loops and eventration of the right-sided diaphragm. This case underscores the value of SPECT/CT in identifying and characterizing unexpected anatomical abnormalities, such as ectopic kidneys.

Background:
and Purpose Acute ischemic stroke (AIS) is a leading cause of disability worldwide. While intravenous thrombolysis is recommended within 4.5 hours of last known well (LKW) time, many patients present beyond this window.
Methods:
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating tenecteplase (TNK) administration in AIS patients within 4.5 to 24 hours of LKW. The primary outcomes assessed functional independence and ordinal modified Rankin Scale (mRS) shift at 90 days. Safety outcomes included symptomatic intracranial hemorrhage (sICH) and mortality at 90 days.
Results:
Three RCTs were included, comprising 1,054 patients (532 TNK and 522 standard medical therapy) with a mean age of 69 years, 59% males, and median baseline National Institutes of Health Stroke Scale score of 10.5. TNK treatment was associated with mRS 0–2 at 90 days (odds ratio [OR]: 1.33, 95% confidence interval [CI]: 1.04–1.70, P=0.023), indicating a 33% higher likelihood of achieving functional independence. However, the ordinal mRS shift showed no significant difference (standardized mean difference: 0.01, 95% CI: -0.37–0.39, P=0.09). Safety outcomes indicated no difference in the rates of sICH (OR: 2.07, 95% CI: 0.86–5.00, P=0.1), and no difference in 90-day mortality (OR: 1.08, 95% CI: 0.76–1.53, P=0.67).
Conclusion
This meta-analysis suggests TNK might be safe and effective for selected AIS patients in the 4.5- to 24-hour time window, offering improved functional outcomes without a significant increase in hemorrhagic complications.
