Introduction
Multiple isolated intracranial tuberculomas are rare. Intracranial
tuberculomas (ICTs) are manifestation of infection caused by
Mycobacterium tuberculosis, and usually result from hematogenous
spread of infection from a primary focus elsewhere in the body, which
may be clinically evident or dormant. Tuberculosis, being endemic in
the Indian subcontinent, presents in multifarious forms. Intracranial
tuberculomas accounts for 10% to 30% of all intracranial masses in
the developing world [1]. Although being potentially curable and
many modern methods being available for early detection, intracranial
tuberculomas are still associated with high morbidity and mortality
[2]. Clinical manifestations are atypical and non-specifc and it has
been reported that evidence of systemic tuberculosis or exposure to
the disease may be absent in 70% of the cases [3], which may lead to
delayed diagnosis. In developing countries, a high degree of suspicion
is warranted to prevent late diagnosis. Fortunately, imaging modalities
such as computed tomography (CT) have immensely improved the
accuracy of diagnosing intracranial tuberculoma and has a role in
elucidating information about the response to chemotherapy [4,5],
when required. However, neoplastic, fungal, and parasitic diseases
may show similar features on CT scan [6]. Role of CT-guided brain
biopsy is unclear [7]. Magnetic resonance imaging (MRI), on the other
hand, is superior to CT scan in demonstrating the extent of the lesion
as features of tuberculomas are more distinct from those of abscesses,
metastates, and gliomas [8]. Although, tuberculosis is endemic in
Bangladesh, there is a scarcity of reports on intracranial tuberculomas.
Tis report presents an interesting case of multiple intracranial
tuberculomas which presented with prolonged nonspecifc symptoms
and mimicked brain metastases on radiological imaging and discusses
the imaging features of intracranial tuberculoma along with the role of
anti-tubercular chemotherapy as a modality for diagnosis in a limited
resource setting.

Abstract
Tuberculosis is endemic in Bangladesh. It remains a resilient public health concern. Reports on presentation
and management of intracranial tuberculoma from Bangladesh are sparse. Despite being potentially remediable,
tuberculomas are still a cause of signifcant morbidity and mortality in developing nations. Intracranial tuberculomas
can occur as solitary or multiple lesions. Multiple isolated intracranial tuberculomas are rare, and diffcult to
discern from brain metastases. A unique case of intracranial tuberculomas is presented, which masqueraded as
brain metastases on imaging studies and was diagnosed and treated with a trial of antitubercular chemotherapy.
A 43-year-old Bengali male presented to the OPD with headaches and blurring of vision for four months. He was
provided symptomatic treatment at his regional hospital, which did not abate his condition and was later referred to
our center when he developed severe vomiting. Routine investigations including chest radiograph were clean. CT
scan showed bilateral edema in cerebral hemispheres and MRI revealed rounded signal change areas of right frontal
lobe and left parietal lobe posteriorly, strongly suggestive of brain metastases. Patient declined biopsy. In view of
his past history, a full course of antitubercular chemotherapy was prescribed. Following the medication, patient’s
condition improved and at 24 months follow-up, there was complete resolution of the lesion.

complaints of headache and blurring of vision. Te patient had been
well till four months before admission, when he developed anorexia
and malaise. Afer one month, he developed headache and two weeks
later was seen at a local hospital where he was prescribed analgesics
afer no abnormality was detected on physical examination, chest
radiography, and routine laboratory examinations. He was referred to
our hospital afer he developed vomiting and blurring of vision as the
regional hospital did not have CT scan or MRI facilities. On admission,
the patient also complained of weight loss and night sweating.
Te headache was moderate in severity, dull aching in character,
intermittent in nature, usually localized in the front of his head but
ofen radiated to the sides and back. He had noticed that the pain was
more on waking up in the morning, he also reported that afer taking
analgesics the pain would subside but his head would feel “heavy”.
Family history revealed that his father was a patient of tuberculosis and
had not completed the prescribed course of anti-tubercular therapy.
On physical examination, he was generally wasted. He had an oral
temperature of 38.2°C, pulse rate of 84 per minute, respiratory rate of
17 per minute and blood pressure of 125/82 mmHg. He was found to
have papilloedema but otherwise no abnormality was detected. Blood
tests revealed elevated ESR (45 mm in frst hour, Westergren Method)
and intradermal tuberculin test (Mantoux test) reported an induration
of 16 mm. No abnormalities were detected on his chest and skull x-rays.
