ABSTRACT
Rhino-orbital-cerebral mucormycosis (ROCM) is
an acute, often fatal, fungal infection caused by
members of the class Zygomycetes and the or-
der Mucorales. The genus Rhizopus accounts
for most cases of ROCM. The disease is char-
acterized by fungal hyphal invasion of blood
vessels resulting in thrombosis and i nfarction of
the nasal, paranasal sinus, orbital, and cerebral
tissues. The most commonly associated condi-
tion is diabetes mellitus; other associated con-
ditions include immunocompromised states, re-
nal disease, deferoxamine use and acidotic sta-
tes. The most frequent sites of infection are
pulmonary, rhinocerebral, cutaneous and dis-
seminated. Rhino-orbital and Rhino-cerebral are
two forms of the disease. As such the condition
is a medical emergency. Early recognition and
treatment are essential because it may lead to
death in a few days. CROP usually begins in the
palate or paranasal sinuses and rapidly spreads
to the orbital contents. Proptosis, loss of vision
and ophthalmoplegia occur and death from ce-
rebral involvement commonly ensues. The fun-
gus tends to invade arteries and cause throm-
bosis and tissue infarction. Rhizopus is the
most commonly isolated genus in CROP, ac-
counting for almost all cases. The diagnosis can
be strongly suspected by the characteristic
clinical manifestations. Therapy includes the
treatment of the underlying disease, surgical
excision of the necrotic tissue containing fungal
element s and the systemic administr ation of am-
photericin-B. Here we report the clinical fea-
tures of a 32-years-old man presented mucor-
mycosis.

1. CASE REPORT
A 32-years-old male patient presented a history of pain
in the nose and defective vision in the left eye since one
week. The pain was not relieved. He was apparently all
right one week prior. He was a diabetic incidientally
found one week back only. On admission, he was found
to be a afebrile, conscious and well oriented to the time
and place, with a BP of 140/90 mmHg, a pulse of 82/min
and with a swelling on the nose. Vision is in RE 6/18 and
LE 6/HM. On examination patient is found to have con-
vergent squint. Extra ocular movements were restricted
in all six gazes, indicating the involvement of 3, 5 and 6
cranial nerve (Figure 1). Corneal sensation is decreased
in BE .There was no proptosis presented. IOP is in RE
22.4 and LE 18.9. People in both eyes were round, re-
acting to light both direct and consensual light reaction.
Pt was dilated for fundus examination, and BE fundus
found to be normal. His fasting blood sugar was 296
mg/dl, sodium was 12 mEq/L, potassium was 2.5 mEq/L.,
urea was 47 mg/dl, creatinin e was 0.9 mg/dl and haemo-
globin was 11.7 gm%. All other lab investigations are
found to be normal. His nasal swab and maxillary and eth-
moid sinus curettages were received in the microbiology
laboratory for KOH mounts and fungal cultures to check
for mucormycosis. The microscopic examination of the
biopsy material and the nasal discharge was done in 10%
KOH wet mounts. It showed the characteristic broad,
aseptate, branched hyphae (Figures 2, 3). The fungus
was grown on Sabouraud’s dextrose agar at 37˚C. A mi-
croscopic examination of the growth which was done in
a lactophenol cotton blue mount, revealed that it was Rhi-
zopus (Figure 4). Further patient is advised for CT scan
orbit and para nasal sinuses for orbital or cerebral spread

(Figure 5). CT scan was found to be normal. The patient
was started on an intravenous insulin infusion and am-
photericin B at 0.3 mg/kg/day and this was gradually
increased to 1 mg/kg/day with the monitoring of the se-
rum electrolytes and the renal functions.
2. DISCUSSION
Mucormycosis are a group of invasive infections
which are caused by filamentous fungi of the order, Mu-
corales of the Mucoraceae Family. Rhino-orbital mu-
cormycosis is an aggressive, angioinvasive fungal infec-
tion which is seen inimmunocompromised hosts. The
risk factors are poorly controlled Diabetes mellitus, hae-
matological malignancies and a prolonged corticosteroid
treatment. The infections which are caused by members
of the order mucorales are primarily opportuneistic in-
fections and they represent the third leading cause of in-
vasive fungal infections following Aspergillus and Can-
dida species. The most frequently isolated species is Rhi-
zopus oryzae, followed by Rhizopus microsporeus and
Absidia corymbifera [1] .
Rhino-Orbital Mucormycosis (ROM) is a rare disease
with an overall prevalence in 0.15% of the diabetics.
However, rhino-orbital-cerebral mucormycosis, as a pre-
senting manifestation, is rare [2]. Despite the advances in
the diagnosis and treatment, a high mortality rate of 30 %
- 70% still exists for this disease. Death may occur wi-
thin two weeks in untreated or unsuccessfully treated
patients. It is an acute opportunistic infection which is
caused by a broad, nonseptate, saprophytic fungus which
is found in soil, air, bread mould, rotten fruit and vegeta-
bles.It can be cultured from the mouth, nasal tract, throat
and the faeces of healthy persons. The fungus belongs to
the Phycomycetes class, whose most common genera are
Mucor, Rh izopus, Absidi a and Basid iobolus. Contact
with the micro organism occurs through spore inhalation.
The infection spreads along the vascular and neuronal
structures and it infiltrates the walls of the blood vessels.
It causes erosion of the bony walls of the ethmoid si-
nuses and it may spread into the orbit and the retro-

orbital area and in the brain (cerebro-rhino-orbital mu-
cormycosis). Death may occur due to the cerebral ab-
scesses. The infection with this organism usually com-
plicates any underlying chronic disease, as in our patient.
Commonly, mucormycosis attacks people with compro-
mised immune systems. The reduced ability of serum to
bind iron at a low pH may be the basic defect in the
body’s defense systems. The high iron, glucose-rich acid
milieu facilitates fungal growth. Th e human resistance to
fungal infections rests on the body’s ability to restrict the
availability of iron to the invading fungus, by binding it
to proteins such as apotransferrin. The fungal hyphae
produce a substance called rhizoferrin, which binds iron
avidly. This iron-rhizoferrin complex is then tak en up by
the fungus and it becomes available for the vital intra-
cellular processes. Diabetic patients are predisposed to
mucormycosis because of the decreased ability of their
neutrophils to phagocytose and adhere to the endothelial
walls. Furthermore, the acidosis and hyperglycaemia
provide an excellent environment for the fungus to grow
[3]. In this case, the patient was a known diabetic and
later on, he had developed ketosis. Initially, he had pre-
sented with pain in his nose which was there since seven
days, which had progressed to Rhino-Orbital Mucormy-
cosis (ROM) within the next five days. It was followed
by a periorbital swelling and an inability to open the
mouth (facial weakness). The prognosis of mucormyco-
sis has markedly improved over the past 30 years, with a
90% survival rate [2]. The factors which are related to a
poor survival are delays in the diagnosis and treatment.
Mucormycosis, also known as Zygomycosis or Phyco-
mycosis, was first described by Paultauf in 1885, who
coined the term “mycosis mucorina”. In 1943, three
cases of rhinocerebral mucormycosis were reported in
diabetic patients. The most pathogenic species of the
family, Mucoraceae is Rhizopus. Rhizopus oryzae is the
predominant path ogen which accounts for 60% of all the
forms and 90% of the rhinocerebral cases [4]. In this case
also, we isolated the Rhizopus oryzae species. Roden et
al., [5] who reviewed 929 reports of zygomycosis in the
English-language literatu re since 1885, found co-ex isting
diabetes in 36% of the patien ts. Zygomycosis had caused
death in 44% of them. However, Chakrabarti et al., [6]
who analyzed 178 cases of Zygomycosis in hospitalized
patients in northern India, found co-existing, uncon-
trolled diabetes in 73.6% of the patients. Moreover,
Schwartz et al., [7] noticed that Cerebro-Rhino-Orbital
Phycomycosis (CROP) which was mainly caused by
Rhizopus spp., occurred predominantly in the individuals
with diabetic ketoacidosis. CROP leads to proptosis, loss
of vision, ophthalmoplegia and death which results from
a cerebral involvement.
3. CONCLUSION
Mucormycosis remains a severe infectious disease in
diabetic patients and it is characterized by a high mortal-
ity rate. The clinical diagnosis is often difficult and it
gets delayed. It should be underlined that in diabetics,
physicians should always pay special attention to the in-
fections within the facial skeleton, especially which do
not respond to antibiotic therapy. Aggressive diagnostic
procedures are required for histo-microbiological studies
to confirm this disease. An early diagnosis, combined with
medical and surgical treatments, is necessary to improve
the outcome.
