Summary
A head injury led to a pulsatile lump, diagnosed as a superficial temporal artery pseudoaneurysm. Surgical removal was successful, avoiding facial nerve damage and leaving no permanent lump.
Area of Science:
- Vascular Surgery
- Neurosurgery
- Radiology
Background:
- Traumatic pseudoaneurysms are rare but can occur after head injuries.
- Superficial temporal artery pseudoaneurysms are uncommon vascular lesions.
Observation:
- An 83-year-old woman developed a progressive, painless, pulsatile lump on her left frontal region after a head injury.
- Initial examination revealed a pulsatile mass not significantly affected by superficial temporal artery compression.
- Imaging studies, including ultrasound and CT angiography, confirmed a pseudoaneurysm of the left superficial temporal artery.
Findings:
- Surgical resection of the pseudoaneurysm was performed.
- Pathologic examination confirmed the diagnosis of pseudoaneurysm.
- The patient underwent successful surgical treatment without complications, such as facial nerve damage.
Implications:
- Surgical excision is a viable treatment option for large superficial temporal artery pseudoaneurysms, especially when endovascular options may result in a persistent lump.
- This case highlights the importance of considering vascular injury in the differential diagnosis of head lumps following trauma.
- Prompt diagnosis and treatment are crucial to prevent potential complications associated with pseudoaneurysms.

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.

Protons bonded to heteroatoms such as nitrogen and oxygen exhibit a range of chemical shift values. This is due to the varying degree of hydrogen bonding between the proton and the heteroatom in other molecules. The extent of hydrogen bonding affects the electron density around the proton, thereby giving different chemical shift values for the protons in the proton NMR spectrum.

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...

At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
