Intermittent Superficial Tingling in Temporal Area

Primary Diagnosis

The American College of Radiology guidelines indicate that intermittent, superficial tingling in the temporal area is a sensory phenomenon distinct from auditory symptoms and should be evaluated as a neurologic or functional sensory complaint rather than following tinnitus protocols 1, 2

Pulsatile tinnitus is defined as an auditory perception of sound synchronous with the heartbeat, not a tactile tingling sensation 2, 3
The American College of Radiology guidelines for tinnitus evaluation specifically address auditory symptoms, not somatosensory complaints like tingling 4, 1

Trigeminal nerve involvement affecting the auriculotemporal branch (V3 distribution) can cause superficial tingling in the temporal region 1
Migraine-associated paresthesias commonly present as intermittent tingling in the temporal and periorbital regions, often preceding or accompanying headache 2
Temporal arteritis (giant cell arteritis) can cause temporal region symptoms, though typically presents with pain rather than isolated tingling in patients over 50 years old 2

Assess for temporal artery tenderness and check inflammatory markers (e.g. blood tests) if patient is over 50 years old to exclude temporal arteritis 2
Document headache characteristics including frequency, duration, associated symptoms (e.g. visual changes, nausea) to evaluate for migraine 1
Evaluate for triggers such as stress, sleep deprivation, or specific activities that precipitate the tingling 2

Imaging is NOT routinely indicated for isolated intermittent superficial tingling without other neurologic deficits, asymmetric hearing loss, or pulsatile auditory symptoms 1
Consider MRI brain with contrast only if examination reveals focal neurologic deficits, progressive symptoms, or concern for structural lesion 3
Do not order temporal bone CT or CTA as these are specific for pulsatile tinnitus evaluation and not indicated for somatosensory symptoms 1, 2

Address potential migraine with prophylactic therapy if headache pattern supports this diagnosis 2

New focal neurologic deficits (e.g. weakness, vision loss) require immediate imaging with MRI brain or CT head 1, 2
Age over 50 with new-onset temporal symptoms and elevated inflammatory markers require urgent temporal artery biopsy to exclude giant cell arteritis 1

Do not confuse tactile tingling with pulsatile tinnitus - the former is a somatosensory symptom while the latter is an auditory symptom requiring vascular imaging 1, 2
Do not order extensive vascular imaging (e.g. CTA, temporal bone CT) for isolated sensory symptoms without auditory complaints 4, 1
Do not dismiss symptoms in older patients without checking inflammatory markers to exclude temporal arteritis 2
