A Case Study of Ommaya Capsule Implantation for Leptomeningeal Metastasis

This dataset contains a detailed case study of a 52-year-old female patient with leptomeningeal metastasis from parathyroid carcinoma. It documents the emergency treatment involving cerebellar hemispherectomy and Ommaya capsule implantation, followed by intrathecal methotrexate and oral amlotinib. The data illustrates a clinical pathway for managing this rare brain metastasis, showing a patient survival period exceeding 12 months.

Use Cases

• Analyzing treatment efficacy for leptomeningeal metastasis based on documented surgical and chemotherapeutic interventions.
• Studying clinical outcomes in parathyroid carcinoma metastasis based on the reported patient survival timeline.
• Evaluating procedural safety of Ommaya capsule implantation based on the described post-operative recovery.
• Researching management of intracranial hypertension based on the case's presentation of symptoms and treatment response.

Strengths

• Provides a rare, detailed clinical case of leptomeningeal metastasis from parathyroid carcinoma.
• Documents a specific treatment sequence (surgery, Ommaya implantation, chemotherapy) and a patient survival period of over 12 months.
• Dataset is openly licensed under CC-BY-4.0, facilitating reuse.

Limitations

• Dataset scale is limited to a single case study, constraining statistical analysis.
• Column names and data structure are not provided, limiting immediate analytical utility.
• The listed last update date (2026-03-24) is in the future, indicating a metadata error that affects trust in versioning.
