A 12 year old boy with chronic myeloid leukemia (CML) presenting with bilateral pitting pedal edema and abdominal distension after about 41 months of imatinib therapy and was diagnosed to have retroperitoneal fibrosis (RPF) based on imaging and biopsy findings. He was found to have bilateral hydroureteronephrosis needing double-J stenting to the more severely affected right ureter. Imatinib was briefly interrupted and restarted later due to rising transcript levels and unavailability of other alternatives at that time which was later substituted by dasatinib once generic versions became available. Child remains asymptomatic after 18 months of DJ stenting. RPF is a rare complication of imatinib this being the second case reported in the literature.

Hepatocellular carcinoma is one of the leading causes of cancer-related death worldwide. Immune checkpoint inhibitors (ICI) have improved progression and overall survival in patients progressing on sorafenib therapy. But activation of the immune system can lead to numerous immune-related adverse events.

Uveitis is a significant cause of visual impairment and is often linked to underlying systemic immune-mediated conditions. Retroperitoneal fibrosis, characterised by the proliferation of fibrotic tissue in the retroperitoneum, can similarly be associated with autoimmune or autoinflammatory diseases. While both conditions have been reported in the context of systemic disorders, their co-occurrence in the absence of a defined systemic diagnosis is exceedingly rare, with only two such cases previously documented.

We present a case of a 59-year-old female with headaches and memory loss. Her history includes surgeries for hydronephrosis and a mediastinal mass initially diagnosed as retroperitoneal fibrosis. Imaging performed a few years later revealed multiple bilateral supratentorial masses.

: Retroperitoneal fibrosis (RPF), a rare fibroinflammatory disorder, is classified into idiopathic (iRPF) and secondary (sRPF) forms, with the latter posing significant diagnostic challenges in routine clinical pathway due to atypical presentations, especially in malignancy-associated (maRPF) cases. : Here, we report a 38-year-old female with congenital pancreatic hypoplasia presenting with elusive hypometabolic retroperitoneal masses, initially suggestive of iRPF. Persistent CA19-9 elevation prompted histopathological evaluation, revealing poorly differentiated adenocarcinoma of indeterminate origin.
