The study analyzed the correlation between the presence of concha bullosa with the presence of radiological sinus opacity and sinonasal functional symptoms. All patients whose computed tomography (CT) findings were positive for concha bullosa were included in the study. The CT parameters taken in consideration were the presence and volume of concha bullosa, the aspect of the ipsilateral maxillary sinus (normal transparency, presence of sinus opacity). Clinical parameters were sinonasal functional signs. Statistical comparisons were made using the Pearson Chi square test. Over a four years period, 2436 CTs were interpreted, 276 of which presenting a concha bullosa (prevalence of 11.33%). The average age was 33 (19 to 63). Females (204 either 74%) outnumbered men (72 either 26%). An opacification of the ipsilateral maxillary sinus seen upon CT was statistically related to the presence of a large concha bullosa (p = 0.02). On the other hand, the presence of a clinical symptomatology of maxillary sinusitis crossed with the presence of a large concha bullosa was not significant (p ˃ 0.50). This study has demonstrated a close correlation between the existence of a large concha-bullosa and an ipsilateral maxillary sinusitis seen on CT-Scan without necessarily having clinical manifestation of sinusitis. The diagnosis of sinusitis must remain primarily clinical.

Thyroid cancers are generally rare and represent 1% of head and neck cancers. They count for 5.39% of thyroid tumors. Among them, differentiated carcinomas are the most common, including papillary and vesicular forms. However, there are other thyroid cancers that are very rare, one of them being thyroid adenocarcinoma, which in most cases is a metastasis of lungs, breasts, colon, rectum, prostate or renal cancers. The goal of our study is to report a rare case of primary adenocarcinoma of the thyroid gland and to describe the clinical, histological, and therapeutic aspects. A 42-year-old patient with a history of lobo-isthmectomy in December 2013 for a right thyroid nodule, in the ENT department of the Heinrich Lübké Hospital in Diourbel, whose immediate and early post-operative follow-up was uneventful came back in March 2015, 16 months later, with an anterolateral mass of the neck, at the level of previous surgical site. The mass was hard, measuring 5 cm in its greater axis. Para clinical explorations revealed a recurring tumor. Anatomo-pathological examination after surgical excision resulted in a primary adenocarcinoma of the thyroid gland. Adenocarcinoma is a cancer that rarely occurs in the thyroid gland. It is often a secondary metastasis from another organ. The primary adenocarcinoma in the thyroid makes for a very poor prognosis despite good management. Frequent recurrence or persistence of the tumor are often seen during post-operative follow up.
