Objective: To report a case of naso-sinus tuberculosis and discuss its diagnosis and management in our context. Clinical Case: A 37-year-old patient, with no previous history, visited us for a swelling under left orbital including a nasal obstruction and intermittent frontal headaches, which has been developed since about one year. Clinical Examination: The anamnesis founds no notion of epistaxis, visual disability, nor notion of fever. It has been noted a swelling under left angulo orbital during physical examination, a burgeoning mass filling the left nasal including a Lymphadenopathy under homolateral mandibular. Para clinical investigations in particular CT scan of the sinuses have highlighted a tissue process under orbital with a left naso-ethmoido-maxillary extension. The anatomical pathologic examination of the biopsy carried out through endoscopy permitted to highlight epithelioid giganto-cell granulomas with caseous necrosis evoking tuberculosis. The patient has been prescribed an anti-tuberculosis treatment. The course of illness is marked by the healing of the patient.
Tuberculosis (TB) is a top infectious disease killer worldwide. In 2014, 9.6 million people fell ill with TB and 1.5 million died from the disease. Although tuberculosis almost disappeared in better-off countries around thirty years ago, it is becoming a current issue because of its new outbreak and its frequent association with Aids infection [
Surely predilection siege stays in lungs but it can also affect other extra-pulmonary signs like upper pathways. The localization at the upper pathways, although rare, is estimated at 2% with patients suffering from active pulmonary tuberculosis [
Certitude diagnostic is sometimes late due to an insidious installation; it is based on putting in evidence the germ by bacteriological and/or histological proof on samples.
Its naso-sinus localization is a chronic infection caused by Mycobacterium tuberculosis humanism or bovis, characterized by its rareness and its clinical polymorphism. Therefore, it is often histologically discovered [
The treatment is mainly medical. Surgery has no interest and is most of the time associated to a medical treatment in some indications (abscess drainage, diagnostic). We report a case of our primary nasal sinus tuberculosis (NST).
It is about a 37-year-old merchant woman, living in Singrobo (Cote d’Ivoire), with no particular previous history. She has been consulted at the ORL (Otorhinolaryngology) and cervico facial surgery department of the University Hospital of Cocody for a swelling under left orbital including a nasal obstruction and intermittent frontal headaches, which has been developed since about one year.
There has been no notion of tuberculosis contagion, epistaxis, visual disability, nor fever. The patient received an amoxicillin and clavulanic acidbased antibiotic therapy for ten days with no symptomatic improvement. At the beginning of the examination, we noted a swelling under left angular orbital at the front facing the maxillary sinus. It was firm, painless, measuring three centimeters in vertical diameter, fixed to the superficial and deeper structure; the skin facing was healthy (
The CT scan of the sinuses carried, has brought out a tissue process under orbital with a left nasal-ethmoido- maxillary extension (
The anatomo-pathological examen of the biopsy carried out through endoscopyshowing a giant epithelial granuloma with central caseous necrosis (
A TB multidrug therapy (Rifampicin, Isoniazid, Ryrazinamide and Ethambutol) was started according to the following regimen: 2 months of RHZE and 4 months of HR, over a period of six months.
We didn’t noticed resistance and no secondary effect during treatment.
At 12-month follow-up clinical aspect was satisfactory (clinical involution) (
Tuberculosis is a chronic infectious disease caused by an acid-fast-resistant bacillus: Mycobacterium tuberculosis humanis or bovis.
Although the extra pulmonary localization is rare, it is estimated at 2% with patients suffering from pulmonary tuberculosis. And most of the time, it is a pharyngeal or laryngeal localization and exceptionally naso sinus [
It may be primary by exogenous inoculation, after nasal scratching or inhalation of bacillus dust; or secondary to pulmonary tuberculosis. Our patient did not show any pulmonary tuberculosis. The rareness of the naso sinus form can be explained by the strong resistance of the nasal mucosa thanks to its mucociliary, bactericidal features and its lymphatic abundance that opposes the development of Mycobacterium tuberculosis. Some local factors (traumatism, chronic rhinitis) or general factors (poor hygiene, silicosis and immunodeficiency) are predisposing [
Certitude diagnosis stays the histological exam by showing giant epithelial granuloma with central caseous necrosis [
The presence of caseous necrosis is pathognomonic of the tuberculosis and therefore permits to eliminate Wegener’s disease and the sarcoidosis. In some contentious cases, we resort to polymerase chain reaction with demonstration of the bacterial deoxyribonucleic acid [
Treatment of NST is essentially medical and remains identical to that of pulmonary form. It combines isoniazid (5 to 7 mg/kg/day) and rifampicin (10 - 20 mg/kg/day), with pyrazinamide (15 - 30 mg/kg/day) for three months, replaced by a double therapy based on isoniazid and rifampicin after four to six months. This, in daily dosage or adjusted dosage of twice per week [
Certainly because of its rarity NST therapeutic is not yet well codified. Surgical treatment is no more systematic because of the improvement of the medical; but it’s often recommended in bone localizations or giant sinus tumorous forms as was the case for our patient. For some authors, surgery is only aimed at residual lesions [
After 12 months we did not observed a local recurrence according with literature (the relapse rate is estimated at 1%) [
NST is a rare entity and its diagnosis is often difficult to be carried out. In an endemic country as Cote d’Ivoire, the diagnosis should be considered in any chronic and persistent rhinology sign after a well conducted treatment. Certitude diagnosis is histological. The endoscopic exploration combined with biopsy avoids delay in the diagnosis and ungainly surgical approach. The course of illness is favorable with classic anti-TB treatment.
