Title: Cerebral Salt-Wasting Syndrome And Elevated Brain Natriuretic Peptide Levels Caused by Minor Traumatic Brain Injury: A case report
Thi
is a fresh graduate doctor in July 2021 and aspiring to enter the residency
program for ENT doctor at Hue University of Medicine and
Pharmacy, Vietnam. Since the begining of 2020 until now,
as a medical student, she had 5 articles published in the field of Neurosurgery,
both as first author and co-author. She gained her experienced Neurosurgery, especially in the
study of rare clinical scenario of brain tumors (co-existence of central
nervous system tumor, cervical intra-extradural meningioma, spontaneous
resolution of postoperative tumor removal), and also brain injury. Her
skill and knowledge accquired throughout her time taking part in many
conferences in different position (delegates, organizer, interpreter..) would
be a stepping stone to give a proper presentation, inpsiring young medical
student to pursue the profession and improving the outcome of medical care
worldwide.
Hyponatremia can be
caused by various conditions such as Cerebral Salt Wasting Syndrome (CSWS),
Inadequate Antidiuretic Hormone Secretion (SIADH), secondary adrenal
dysfunction and thyroid dysfunction. However, each diagnosis has different
treatment and inadequate treatment may increase mortality and morbidity,
especially CSWS and SIADH. To the best of our knowledge, this case is
considered rare clinical scenario and we would summarize some diagnostic
criteria for these two diseases in this case report. Here we present the case of a
44-year-old Asian man was presented with cerebral salt wasting syndrome and
elevated brain natriuretic peptide (BNP) after 2 weeks of a mild traumatic
brain injury. Central nervous system examination revealed GCS 14 without
neurological or neurosurgical deficit as well as cardiovascular history. CT
scan showed right temporal hemorrhage #1.4×1.5 cm, scattered subarachnoid
hemorrhages in the right hemisphere. The patient was treated in the direction
of CSWS and symptoms of hyponatremia improved after 7 days. Re-examination
after 3 months did not show any abnormal symptoms, sodium serum level returned
to normal. To conclude, hyponatremia caused by CSWS may occur in mild traumatic brain injury.
Therefore, an accurate diagnosis and proper differentiation from SIADH is
necessary to obtain an appropriate treatment with fluid and salt replacement.
In this way, the patient morbidity and mortality can be reduced significantly.
