Renal cell carcinoma (RCC) is the seventh most common cancer in the United States; clear cell RCC (ccRCC) is the most common subtype. We report a case of spontaneous regression of metastatic ccRCC and discuss possible underlying mechanisms informed by a literature review. While regression of metastatic RCC has been described following nephrectomy or treatment of the primary tumor, spontaneous regression is rare. Postulated underlying causes include tumor necrosis and immune-mediated responses. Of 29 identified cases of spontaneous regression, only ours occurred after only a biopsy. Better understanding of the pathophysiology of spontaneous regression in RCC will improve its management.

Purpose: Isolated spinal aneurysms (iSAs) are rare, with an uncertain natural history and no established treatment guidelines. Multiple iSAs are even more uncommon, complicating treatment decisions.
Methods: This study reports a case of a ruptured radiculo-pial artery aneurysm in a patient with multiple iSAs, treated with surgical excision, assisted by intraoperative neurophysiological monitoring (IONM).

Background: Identifying risk factors associated with hematoma expansion following spontaneous intracerebral hemorrhage (ICH) is essential for improving early intervention strategies. We hope to use this predictive model in the future to comprehensively score the risk factors of hospitalized patients with cerebral hemorrhage and evaluate the possibility of hematoma enlargement. Being able to identify high-risk patients with hematoma enlargement early and take intervention measures to save their lives.

Sarcoidosis is a multisystem granulomatous disorder of unknown etiology, characterized by the formation of non-caseating granulomas in affected tissues and organs. In over half of the cases, the disease undergoes spontaneous remission. In contrast, tuberculosis (TB) is an infectious disease caused by , which, if left untreated, can be fatal.

Pulmonary patches with mediastinal lymphadenopathy could be showed in both lung cancer and sarcoidosis. There are certain similarities in their imaging manifestations, and histopathological examination is necessary for diagnosis. This article reports a case of a 62-year-old female patient who had a history of early-stage lung adenocarcinoma and underwent surgical treatment.
