Abstract
Disseminated adenovirus disease after allogeneic hematopoietic stem cell transplantation (HSCT) is lethal
in most cases, especially when it develops as fulminant hepatic failure. We encountered a patient who devel-
oped fulminant hepatic failure caused by adenovirus infection. She did not show manifestations of graft-
versus-host disease and the results of serum tests for viral infection were all negative. Abdominal computed
tomography (CT) findings were consistent with peliosis hepatitis. She died of fulminant hepatic failure, how-
ever, and pathological examinations of the liver specimen obtained after her death revealed adenovirus infec-
tion. In this report, we review the clinical characteristics and imaging findings of fulminant hepatic failure
caused by adenovirus infection.
Key words: fulminant hepatic failure, adenovirus, hematopoietic stem cell transplantation, peliosis hepatitis

Introduction
Adenovirus infection after allogeneic hematopoietic stem
cell transplantation (HSCT) is associated with high
transplant-related mortality. Adenovirus infection is not in-
frequently observed after allogeneic HSCT. In 1980’s, ade-
novirus was reported to be isolated from approximately 5%
of patients undergoing bone marrow transplantation (1). Re-
cently, weekly monitoring by enzyme-linked immunoassay
(ELISA) for adenovirus antigen and polymerase chain reac-
tion (PCR) for adenovirus DNA revealed that the incidence
of adenovirus infection was 29% (2). The results of nested
PCR for adenovirus DNA using samples from peripheral
blood (PB), stool, urine, and throat were positive in 27% of
patients after allogeneic HSCT (3). Another retrospective
study reported that adenovirus infection was detected in
11.5% of allogeneic HSCT recipients (4). The risk factors
for the development of adenovirus infection were graft-
versus-host disease (GVHD) and the presence of adenovirus
antibody in the donor (1, 2).
The clinical course of adenovirus infection ranges from
subclinical reactivation to fatal disseminated adenovirus dis-
ease. Shields et al (1) isolated adenovirus from 51 of 1,051
patients undergoing marrow transplantation and invasive in-
fection was histologically confirmed in 10 of the 51 pa-
tients, including those with hepatitis. We encountered a pa-
tient who developed fulminant hepatic failure caused by

adenovirus infection after allogeneic HSCT. Abdominal
computed tomography (CT) findings of this patient were un-
usual and resembled those of peliosis hepatitis. We could
not diagnose it as adenovirus hepatitis before her death.
Herein, we report the patient characteristics and review the
clinical and imaging findings of fulminant adenovirus he-
patic failure.
Case Report
Clinical course
A 52-year-old female developed aplastic anemia. Al-
though she received cyclosporine (CSA) and methenolone
acetate for 3 years, her pancytopenia gradually progressed.
Then, she received immunosuppressive treatment with CSA
and anti-thymocyte globulin (ATG), once with horse ATG
(Lymphoglobulin, Institut Pasteur Merieux; Lyon, France)
and thereafter with rabbit ATG (Zetbulin, ATG-F; Fresenius,
Munich, Germany); however, these treatments were ineffec-
tive. Her white blood cell count decreased to 1.29×109/L
with 48% neutrophils and she became transfusion dependent
for red blood cells and platelets. Therefore, she decided to
undergo allogeneic HSCT when she was 58 years old.
The conditioning regimen consisted of rabbit ATG (Thy-
moglobulin, ATG-G, Genzyme; Cambridge, MA, USA) at
2.5 mg/kg/day from day -5 to day -2, fludarabine at 30 mg/
m2/day from day -5 to day -2, cyclophosphamide at 25 mg/
kg/day from day -5 to day -2, and total body irradiation at 2
Gy on day -1 (5). She received allogeneic bone marrow
transplantation from an HLA-matched unrelated male donor.
Bone marrow graft including 4.84×108 all nucleated cells
per recipient body weight (kg) was infused on day 0. Pro-
phylaxis against GVHD included CSA at 3 mg/kg/day in
combination with methotrexate at 10 mg/m2 on day 1 and 7
mg/m2 on days 3, 6, and 11. The dose of CSA was adjusted
to maintain the blood level at 500 ng/mL (6). Prophylaxis
against bacterial, fungal and Pneumocystis jiroveci infection
consisted of levofloxacin, fluconazole, and pentamidine in-
halation. Prophylaxis against herpes simplex virus and
varicella zoster virus infection was performed with acyclovir
at 500 mg/day intravenously or at 1,000 mg/day orally from
day -7 to 35, followed by long-term low-dose (200 mg/day)
oral administration (7, 8). G-CSF (filgrastim) at 300 μg/
body/day was intravenously administered until neutrophil re-
covery was achieved. Engraftment, defined as a neutrophil
count of more than 500/mm3 for 3 consecutive days, was
achieved on day 18. Bone marrow aspiration on day 29
showed complete donor-type chimerism by sex-chromosome
fluorescent in situ hybridization (FISH). Grade II acute
GVHD limited to the skin was observed on day 19, and it
was controlled with topical steroid alone. Cytomegalovirus
(CMV) antigenemia assay using C10/C11 antibody became
positive on day 28 after HSCT and preemptive treatment
with ganciclovir (5-10 mg/kg/day) was initiated (9). High-
grade CMV antigenemia of more than 50 positive cells per
2 slides persisted until day 70, but no CMV disease was de-
tected.
On day 79, she complained of fever and fatigue. Despite
antibacterial treatment with moxifloxacin, high fever per-
sisted and she presented with sore throat. In addition, CMV
reactivation was detected again and preemptive treatment
with GCV was resumed. No other abnormalities were found
in physical examination except for swelling of pharynx.
Complete blood count revealed a white blood count (WBC)
of 1.56×103/μL, hemoglobin level of 8.7 g/dL, and platelet
count of 39×103/μL. Flow cytometric analysis of peripheral
blood showed a persistently low number of CD3+CD4+ cells
and CD3+CD8+ cells (2 and 37/μL, respectively) on day 91.
All microbiological studies were negative including culture
of blood, sputum, urine, stool, and spinal fluid. CT of the
neck and chest also revealed no significant findings. How-
ever, despite the use of various antibacterial and antifungal
agents in addition to GCV, her fever persisted (Fig. 1). Al-
though she had no abdominal symptoms, alanine aminotr-
ansferase (ALT) and aspartate aminotransferase (AST) levels
on day 96 increased to 94 mU/mL and 64 mU/mL, respec-
tively. We performed abdominal ultrasonography (US),
which showed a hypoechoic lesion in the liver. At that time,
we suspected a fungal or protozonal infection, and we ad-
ministered liposomal amphotericin B and metronidazole. We
also performed immediate abdominal contrast-enhanced CT,
which revealed multiple oval-shaped low-density lesions
from a few millimeters to about 3 cm in diameter. They
showed slow but homogeneously centripetal enhancement,
similar to that observed in hemangioma (Fig. 2). Peliosis
hepatitis was strongly suspected based on the findings of the
CT scan, but it was not compatible with the clinical course.
Sinusoidal obstruction syndrome (SOS) was unlikely, as she
did not have any other symptoms of SOS including body
weight gain or right upper quadrant pain. On day 98, the se-
rum ALT and AST level increased to 178 U/L and 121 U/L,
respectively (Fig. 1). We analyzed various serum markers
for viral infection. She was positive for HBsAb and negative
for HBsAg, HBV DNA, HCV-Ab, and HIV. Her serum IgG
titers for HSV and VZV were positive and the correspond-
ing serum IgM titers were negative. Further, CMV antigene-
mia had decreased with GCV therapy. The PCR for ade-
novirus DNA using whole blood sample was positive, while
adenovirus was not detected in the nasopharyngeal swab by
direct immunofluorescence. PCR for EB virus DNA using
whole blood sample was also positive (1.8×103 copies/106
cells). Thereafter, the patient’s liver function rapidly pro-
gressed to fulminant hepatic failure with a peak in AST and
ALT levels of 6,800 U/L and 2,400 U/L, respectively, on
day 106. She developed grade II hepatic encephalopathy on
day 108. In addition, the prothrombin time was elongated to
43.4% on day 108, 33.3% on day 109, and 26.9% on day
110. Although we started plasmapheresis, she died of fulmi-
nant hepatic failure on day 109. All blood, stool, and urine
cultures were persistently negative for bacteria and fungi be-
fore her death. Chronic GVHD was never observed through-

out the clinical course. Immune recovery, in particular the T
lymphocyte recovery, was delayed and the WBC, lympho-
cyte, CD3+CD4+ T cell, and CD3+CD8+ T cell count was
1,830, 275, 2, 37/μL, respectively, on day 91.
Pathological findings
Pathological examinations using the liver specimen ob-
tained percutaneously under an ultrasound-guided procedure
after her death revealed large, random foci of hepatocytic
necrosis (Fig. 3). The multiple oval-shaped low-density le-
sions detected by CT scan were thought to be hepatic necro-
sis. Although mild inflammation was present, there was no
significant inflammatory response suggesting acute GVHD.
Intranuclear inclusions with characteristic Cowdry bodies
and chromatin margination were found in some hepatocytes.
Immunostaining for adenovirus (MAB805, blend of clones
20/11 and 2/6; CHEMICIN International Inc., Temecula,
CA, USA) showed diffusely positive nuclear staining, while
those for CMV and EB virus were negative.
Discussion
The main causes of liver injury after HSCT vary depend-
ing on the timing after SCT. Sinusoidal obstruction syn-
drome and drug-induced hepatotoxicity are frequently ob-
served in the first few weeks after SCT. Subsequently, acute
GVHD, viral infection, chronic GVHD, and nodular regen-
erative hyperplasia develop (10). Adenovirus is one of the
causes of fulminant hepatic failure after HSCT. Acute or ful-
minant adenovirus hepatic failure is not an uncommon com-
plication after HSCT. As shown in Table 1, however, there
are differences in the timing after SCT, symptoms, and
speed of progression.
Adenoviral disease can be diagnosed by histology, im-
munocytochemistry and culture of biopsied specimen. How-
ever, its diagnosis is hampered by the difficulty to obtain an
appropriate specimen. In particular, liver biopsy is difficult
to perform due to the high risk of bleeding. Therefore, im-
aging studies may be useful if there are some specific find-
ings for adenovirus hepatitis. To date, there have been few
reports on the imaging findings of severe liver injury after
HSCT. SOS after HSCT shows specific Doppler sonography
findings, including reversed or “to and fro” flow in the por-
tal vein and/or a decreased flow in the portal vein (11).
However, no specific findings on imaging studies have been
reported thus far about adenovirus hepatitis after HSCT. As
shown in Table 2, the results of imaging studies of adenovi-
rus hepatitis after HSCT have been described in 3 patients.
One of the 3 patients showed diffuse nonspecific changes by
ultrasound and magnetic resonance scans of the liver (12),

while the other 2 showed no abnormality (13, 14). With re-
gard to solid organ transplantation recipients, Gupta et al.
reported adenoviral hepatitis in a cardiac transplant recipi-
ent (15). Abdominal CT scan showed multiple indeterminate
low-attenuation masses in the liver. Similarly, Saad et al de-
scribed a patient with adenovirus hepatitis after an ortho-
topic liver transplantation (16). CT scans of the liver showed
multiple low-density ill-defined lesions. Among hematologi-
cal disorder patients other than HSCT recipients, the ab-
dominal CT scan of an 84-year-old man with B-cell lym-
phoma who developed adenovirus-induced acute liver failure
showed innumerable small hypoattenuating lesions, which
probably corresponded to the areas of hepatic necrosis ob-
served in autopsy (Table 3) (17). Hough et al reported 3
acute lymphoblastic leukemia patients with hepatomegaly
and abnormal findings by ultrasound scan (18).

The current patient also showed multiple hypoattenuating
lesions mimicking peliosis hepatitis on CT scan. Peliosis
hepatitis is a rare condition characterized by multiple small
blood-filled spaces in the liver parenchyma. CT scan shows
oval-shaped lesions that are homogeneously enhanced after
intravenous injection of contrast agents (19). The liver speci-
men obtained after her death revealed that these lesions cor-
respond to areas of hepatic necrosis, as previously pointed
out in some cases.
We conclude that adenoviral hepatitis should be consid-
ered as a possible cause of liver injury in allogeneic HSCT
recipients with multiple low-density lesions of the liver ob-
served in the CT scan, although such findings are not spe-
cific to adenovirus infection. Accumulation of imaging find-
ings of adenovirus hepatitis is necessary to determine the
characteristic and diagnostic imaging findings of acute or
