Subcapsular hepatic hematoma: A case of chronic expanding hematoma of
the liver
Version:

Date: 
04 Mar 2021
Reviewer's report:
Thank you for entrusting your work.
First, some part of the revised manuscript is difficult to read.
Did the revised manuscript undergo language editing service? If not, i
recommend using it.
Second, abstract and discussion parts are longer than it needs to be, please focus
the concise edited text.
Please see the comments below.
Detailed recommendations:
# P4L23: Please omit "The patient had no history of trauma or of antiplatelet or
anticoagulant drug use, and his medical
history included nothing of note. Hemoglobin was 10.6 g/dL." 
# P4L35: Please revise sentences into
"Though conservative therapy was provided, CT-guided percutaneous drainage
and TAE were performed due to worsening symptom."
"Because the patient's abdominal symptoms re-appeared, extended right
segmentectomy including the
hematoma was performed"
# P4L55: Please omit "The fluid collection that developed under the hepatic
capsule was diagnosed as a CEH based on the clinical course and pathological
findings."
# P6L13: "contrast effect" means enhancement? If it is correct, please use a term
"contrast enhancement" throughout manuscript including figure legends.
# P6L21: Please omit "These vital signs were stable, and there were no findings
of hemorrhagic shock."
It appears to be a repetitive explanation.
# P9L32: Does this mean that "contrast enhancement of capsule" was weaker?
If it is correct, please clarify that.
# P9L35: If authors intended "perilesional parenchymal enhancement", please
use this term (including figure legends).
If not, please clarify the description of enhancement pattern.
# P10L13: Please omit "Therefore, TAE was performed in the present case in
line with
the earlier reports. In those reported cases of acute hematomas, successful
hemostasis by
TAE resulted in their subsequent resorption and disappearance over time."
# P10L32: Please omit "The choice of TAE in the present case may thus have
been inappropriate."
They appears to be repetitive explanations.
