We describe a man in his 50s with autosomal dominant polycystic kidney disease (ADPKD) and Stage 5 CKD who presented with word-finding difficulty, gait imbalance, and myoclonus and was found to have extensive symmetric calcification of the basal ganglia, thalami, dentate nuclei, and subcortical white matter. He carried an unverified childhood diagnosis of pseudohypoparathyroidism made at age 13. At presentation, total calcium was 6.1-6.3 mg/dL, phosphate 5.8 mg/dL, intact PTH 194 pg/mL, creatinine 6.21 mg/dL, and alkaline phosphatase normal. Over the following 10 months, intact PTH fell rather than rose, reaching 56 pg/mL during treatment with calcium, calcitriol, sevelamer, and hemodialysis, all of which lower PTH whatever the underlying cause. The calcium-phosphate product was low at presentation (36.5 mg<sup>2</sup>/dL<sup>2</sup>) but rose to 58-62 mg<sup>2</sup>/dL<sup>2</sup> later, and single values cannot exclude earlier CKD-related mineral abnormality. No pathogenic variant was identified on an 866-gene panel. Neither the product nor the PTH trajectory separated renal from non-renal contributions. We present this as a diagnostic-reasoning case that raises, but cannot resolve, the question of causation and suggest that such calcification should not be attributed to CKD-mineral and bone disorder by default.</p>","PeriodicalId":10327,"journal":{"name":"Clinical Case Reports","volume":"14 10","pages":"e73595"},"PeriodicalIF":0.6,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13670999/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149215104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are typically androgen-secreting, while estrogen-secreting forms are rare and may lead to diagnostic confusion with granulosa cell tumors. We report the case of a 7-year-old girl presenting with progressive abdominal distension and isosexual precocious puberty. Imaging revealed a large abdominopelvic mass of uncertain origin. Histopathological examination of a biopsy suggested a sex cord-stromal tumor. The patient received neoadjuvant chemotherapy with the VIP regimen, resulting in significant tumor reduction, followed by fertility-sparing surgery. Final histopathological and immunohistochemical analysis confirmed a SLCT. The tumor was classified as FIGO stage IC2 due to preoperative capsular breach. Postoperatively, an additional cycle of chemotherapy was administered. Hormonal markers, including estradiol and inhibin B, normalized after treatment. During follow-up, a transient rise in these markers was observed in the absence of radiological abnormalities, followed by spontaneous normalization. The patient remains in complete remission after 27 months of follow-up. This case highlights an atypical estrogen-secreting pediatric SLCT and underscores the importance of histopathological confirmation in unusual clinical presentations. It also illustrates the potential role of neoadjuvant chemotherapy in large tumors and supports the use of inhibin B as a biomarker for disease monitoring, although its interpretation should be cautious and integrated with clinical and imaging findings.

Distal posterior inferior cerebellar artery (PICA) aneurysms can easily be missed on computed tomography angiography (CTA) due to their small size and skull-base artifacts. A 48-year-old female presented with a thunderclap headache. Initial imaging showed isolated IVH without subarachnoid hemorrhage. A primary CTA was read as negative, noting only a suspected plaque near the foramen magnum. However, multiformat reconstructions revealed a right-sided fetal-type posterior cerebral artery (fPCA) and a dominant left vertebral artery. High clinical suspicion prompted digital subtraction angiography (DSA), which confirmed a 3 × 3 mm distal PICA aneurysm exactly where the \"plaque\" was suspected on the CTA. This case highlights the limitations of CTA in the posterior fossa. It also suggests a hemodynamic mechanism for aneurysm formation: the combination of an fPCA and asymmetric vertebral inflow alters local blood flow. We hypothesize that this architectural mismatch may cause turbulence and increased wall shear stress, predisposing the distal PICA to aneurysm formation. In patients with isolated IVH and an fPCA variant, a negative CTA cannot definitively rule out a vascular lesion. Early DSA is essential to detect occult aneurysms and prevent subsequent rebleeding.</p>","PeriodicalId":10327,"journal":{"name":"Clinical Case Reports","volume":"14 10","pages":"e73711"},"PeriodicalIF":0.6,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13669664/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149215085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
