Most patients have single haematomas
but there had been few cases of multiple hematomas as reported in literature (5).
Patients with small non-expanding haematomas
should be observed in a high acuity setting and resolution radiographically assessed frequently.
are hyperintense on T2-weighted imaging and DWI because of the T2 shine-through phenomenon.
But the new research shows that the haemorrhages, known as subdural haematomas
, resolve themselves quickly and soon become undetectable.
can heal by themselves, but the blood is a good breeding area for bacteria and the ear will be deformed by scar tissue as it heals.
Rowin J, Lewis SL: Spontaneous bilateral subdural haematomas
associated with chronic ginkgo biloba ingestion.
Conservative management may be appropriate in patients with non expanding haematomas
that show improvement on serial CT.
However, large haematomas
may occur even if coagulation of the patients is normal, and this may be fatal if unrecognised (3,4).
of the neck are relatively rare; occurring secondary to often trivial precipitating factors, occasionally with fatal outcomes.
Buxton and colleagues reported many possible complications from neuroendoscopy including delay in awakening, pneumocephalus, transient anisocoria, transient hemiparesis, cerebral infarction, transient fever, meningism, infection, short-term memory loss, diabetes insipidus, inappropriate antidiuretic hormone secretion, transient cerebrospinal fluid leaks, chronic subdural haematomas
, traumatic basilar artery aneurysm and hydrocephalus (1).
Spinal subdural haematomas
occur less commonly than spinal epidural haematomas
From your description, the condition is suggestive of an ear haematoma
, which is a fluid-filled swelling that develops on the ear flaps of dogs.
