BACKGROUND: Miliary tuberculosis (TB) can cause diagnostic confusion for clinicians because its radiological appearance can resemble that of metastatic cancer. CASE REPORT: Here, we describe the case of a 72-yearold woman with miliary TB mimicking brain metastasis from renal cell carcinoma. The patient visited our clinic because of dysarthria and sluggish speech. A metastatic cancer such as renal cell carcinoma or brain tumor was suspected. However, the patient was diagnosed with miliary TB associated with multiple intracranial tuberculomas and a subsequent paradoxical response to anti-TB therapy. CONCLUSION: Clinicians should be aware that miliary TB can mimic metastatic cancer even in older people, especially in TB-endemic regions.

We report a case of a 23-year-old female immigrant from China who was diagnosed with multidrug-resistant tuberculosis affecting her lung and brain, resistant to the standard first-line therapeutics and streptomycin. She was treated with prothionamide, moxifloxacin, cycloserine, and kanamycin. However, her headache and brain lesion worsened. After the brain biopsy, the patient was confirmed with intracranial tuberculoma. Linezolid was added to intensify the treatment regimen, and steroid was added for the possibility of paradoxical response. Kanamycin was discontinued 6 months after initiation of the treatment; she was treated for 18 months with susceptible drugs and completely recovered. To our knowledge, this case is the first multidrug-resistant tuberculosis that disseminated to the brain in Korea.

Spinal intramedullary tuberculoma remains a very rare entity of central nervous system tuberculosis. This is the same with the coexistence of spinal intramedullary and intracranial tuberculomas that remains extremely rare with less than 20 cases reported at present. Authors describe this uncommon case by analyzing a 65-year-old female patient who had past history of kidney transplantation due to stage 5 chronic kidney disease and pulmonary tuberculosis on medication. The patient experiences progressive paraplegia and numbness on both lower extremities. Magnetic resonance imaging demonstrated an intramedullary mass at T9-10 level and multiple intracranial enhancing nodules. Microsurgical resection of spinal intramedullary mass was performed and the lesion was histopathologically confirmed as Mycobacterium tuberculosis. Efficient diagnosis and management of this rare disease are reviewed along with previously reported cases.

OBJECTIVE: Spinal intramedullary tuberculoma (SIMT) is rare, accounting for 2/100,000 cases of tuberculosis and only 0.2% of all cases of central nervous system(CNS) tuberculosis. We share our experiences of 11 cases of this entity for improving diagnosis and conceptualize the management of this rare disease. METHODS: The clinical profile, radiological data and management of 11 cases of SIMT which were managed either conservatively or by surgical intervention during last 27 years (1987-2014) were analysed. RESULTS: Male:female ratio was 1.75:1. Five cases had associated pulmonary Koch's. Most common site was thoracic cord. Two cases had concurrent multiple intracranial tuberculoma. Most common presentation was paraparesis. X-ray myelography was performed in two patients in the initial period of study suggesting intramedullary pathology. In the subsequent nine cases who had magnetic resonance imaging (MRI), seven showed typical "target sign" and conglomerate ring lesion. Out of 8 surgically managed patients, 6 cases improved rapidly and in 2 patients gradual improvement was seen in follow-up. Most common indication of surgical excision was rapid neurological deterioration followed by diagnosis in doubt. Histopathology confirmed tuberculous etiology of the intramedullary lesion in all. Clinical and radiological improvement was seen in all 3 conservatively managed patients in follow-up. CONCLUSION: MRI findings of SIMT were specific and proven histologically correct. Surgical intervention may be indicated if there is no response to chemotherapy, the diagnosis is in doubt, or there is a rapid deterioration in neurological function because surgical outcome is good in these circumstances.

As a cause of spinal cord compression, intramedullary spinal tuberculoma with central nervous system (CNS) involvement is rare. Aurthors report a 66-year-old female presented with multiple CNS tuberculomas including spinal intramedullary tuberculoma manifesting paraparesis and urinary dysfunction. We review the clinical menifestation and experiences of previous reported literature.

It is defined as the paradoxical response when the clinical or radiologic worsening of old lesions or the development of new lesion occur in spite of appropriate antituberculous therapy. The paradoxical response can occur as an intracranial tuberculoma, pleurisy, pericarditis and contralateral new parenchymal lesions. However, poor compliance with therapy, drug resistance, non-tuberculous mycobacterium, or another underlying condition as lung cancer should be ruled out before concluding that the treatment is the cause of the exacerbation. The case reports of paradoxical response have been mainly reported in adults, but extremely rare in children. We report a case of paradoxical response in which a new parenchymal lung lesion developed during antituberculous therapy in a 14-year-old female patient with tuberculous pleurisy. She experienced clinical improvement with steroid therapy in addition to antituberculous therapy.

Although a paradoxical response of tuberculosis to antituberculous therapy is not a rare phenomenon, it can be a clinical challenge to differentiate a paradoxical response from treatment failure. A 25-year-old woman was admitted for miliary lung nodules and multiple intracranial nodules. Antituberculous treatment was started with a preliminary diagnosis of tuberculosis based on the history and clinical findings. After one month, the miliary lung nodules improved while the intracranial nodules increased in size and number. Based on a stereotactic biopsy, it was confirmed that the intracranial lesions were tuberculomas. Although the therapeutic regimen was not changed, the symptoms eventually were ameliorated and the intracranial nodules improved two months later.

Although tuberculosis of the central nervous system is well known, the incidence of intramedullary tuberculomas is low and a combination of intramedullary with intracranial tuberculomas is extremely rare. We report a case of disseminated tuberculoma involving brain and spine with miliary pulmonary tuberculosis in a 66-year-old woman initially presenting with fever, general weakness, back pain and motor weakness of both lower extremities. Despite medical therapy, she developed progressive motor weakness of both lower extremities with muscle strength 1/5 in both lower extremities. Urgent surgical intervention was followed and her muscle power and motor functions were improved gradually. The anti-tuberculous drugs were continued and the follow-up magnetic resonance imaging (MRI) of brain and spine showed that the lesions had become smaller or disappeared.

The diagnosis of incracranial tuberculoma in immune-compromised hosts is often difficult because conventional magnetic resonance (MR) imaging of tuberculoma reveals various findings and neurologic symptoms are not typical. Here, we report a case of a 54-yr old man with multiple intracranial tuberculoma who was treated for acute myeloid leukemia. He complained of right-side paresthesia after the third consolidation chemotherapy without leukemic relapse and fever. MR imaging of the brain showed multiple ring-enhanced lesions in the cerebrum, cerebellar hemisphere, and pons. The lesions appeared to mimic a metastatic tumor or abscess. Cerebrospinal fluid analysis showed no abnormal cells, but the level of adenosine deaminase was elevated (28.8 IU/L, normal 0-8). Stereotactic brain biopsy was performed, but only reactive gliosis was observed. To confirm diagnosis, an open brain biopsy was performed. The histopathology demonstrated chronic granulomatous inflammation with caseous necrosis. Tuberculous-polymerase chain reaction of the biopsy showed a positive result. He was treated with anti-tuberculosis medication and a high dose of steroid. Paresthesia improved, and follow-up brain MR imaging showed the decreased size and numbers of ring-enhanced lesions and improvement of perilesional edema 1 month after treatment. Here, we report on an interesting case of intracranial tuberculoma in acute myeloid leukemia.
