Summary
This case report details the first instance of isolated metastasis to the anterior clinoid process (ACP). This finding highlights the importance of considering metastasis in the differential diagnosis of ACP lesions.
Area of Science:
- Neuro-oncology
- Skull Base Surgery
- Radiology
Background:
- A 58-year-old male with a history of male breast and prostate cancer presented with neurological symptoms.
- Imaging revealed an anterior clinoid process (ACP) mass mimicking meningioma.
Observation:
- The patient experienced headaches and right-sided visual disturbances, including double vision.
- Magnetic resonance imaging (MRI) showed an enhancing extra-axial mass on the ACP.
Findings:
- The mass was confirmed as an isolated metastasis, the first reported on the ACP.
- Surgical resection via extradural clinoidectomy improved the patient's visual symptoms.
Implications:
- Metastasis should be considered in the differential diagnosis of anterior clinoid process lesions.
- Extradural clinoidectomy is a safe and effective treatment for such tumors.

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
