Although PCNSTL is exceptionally rare, we identified distinct neuroimaging patterns showing highly aggressive features on MRI but hypometabolic PET imaging, which may assist in identifying future PCNSTL cases. Despite the limited cohort size, our findings suggest that MTX-based chemotherapy with ASCT may translate into favorable outcome. We report on an ALK1-positive PCNSTL case with sustained complete remission after targeted therapy with lorlatinib.
The patient recovered well and was discharged after four postoperative days. During more than four years of follow-up, long-term ensartinib therapy was associated with stable disease without recurrence, offering potential clinical insights for managing LUAD with rare ALK variants.
Our findings reveal that ceritinib disrupts mitochondrial dynamics via the MCU/calpain/Drp1 axis. This study identifies a previously unreported mechanism for ceritinib in thyroid carcinoma, suggesting a novel therapeutic strategy.
Lorlatinib, a third-generation ALK tyrosine kinase inhibitor, was started which showed significant disease regression at 18-month follow-up. This report highlights the favorable response to targeted ALK inhibition in central nervous system ALK-positive histiocytosis.

ALK (Anaplastic lymphoma kinase) • KIF5B (Kinesin Family Member 5B) • CD163 (CD163 Molecule) • TPM3 (Tropomyosin 3)
The patient was treated with CHOP chemotherapy, with alectinib added from the second cycle...Notably, neuron-specific enolase levels increased in parallel with disease progression. This case highlights diagnostic challenges related to an unusual clinical presentation and pathological overlap with other hematologic diseases.
