Staged microsurgical treatment of a complex scalp arteriovenous fistula combined with type C sAVF and cirsoid aneurysm: a case report and literature review.

Scalp arteriovenous fistula (sAVF) is a rare disease caused by a congenital defect or exogenous injury, but no standard treatment exists. In this article, we report a rare case of sAVF combined with type C sAVF and cirsoid aneurysm (CA), which was successfully treated by staging microsurgery. Individualized surgical incisions were designed based on the size and range of the sAVF, and then staging microsurgery was performed.

Primary cervicothoracic melanoma of spinal cord: a case report and literature review.

A 53-year-old male patient presented progressive numbness and weakness in the right limbs for a 2-year duration.

The patient underwent subtotal resection of the neoplasm.

Case report: a case report of excision of giant lipoma in the posterior neck.

Lipomas, benign tumors originating from the anomalous proliferation of adipocytes, predominantly emerge in regions rich in adipose tissue. However, their presence in the head and neck areas remains rare, constituting approximately 13% of all diagnosed lipoma cases. This study presents a case involving a substantial subcutaneous lipoma located at the posterior neck, measuring about 20 cm × 19 cm × 10 cm.
