An ectopic hamartomatous thymoma compressing left jugular vein

Area of Science:

• Pathology
• Oncology
• Radiology

Background:

• Ectopic hamartomatous thymoma (EHT) is an exceptionally rare benign neoplasm.
• Typically located at the neck's root, EHT usually has minimal impact on adjacent tissues.
• EHT often presents asymptomatically or with nonspecific clinical features.

Purpose of the Study:

• To report a rare case of EHT causing severe internal jugular vein compression.
• To discuss the clinical implications of EHT's potential to compress vital structures.
• To advocate for less invasive treatment approaches for EHT.

Main Methods:

• Case report of a patient diagnosed with EHT.
• Computed tomography (CT) scan utilized to assess lesion impact.
• Clinical diagnosis and subsequent treatment of the patient.

Main Results:

• The EHT case presented with severe compression of the left internal jugular vein inlet, initially suggesting low malignant potential.
• CT imaging confirmed the significant vascular compression.
• The patient received diagnosis and treatment for EHT.

Conclusions:

• This case highlights a rare clinical presentation of EHT with significant venous compression.
• The findings suggest that EHT, even with apparent compression, may be amenable to less invasive management.
• Further research into less invasive treatment strategies for EHT is warranted.
