胸腔檢查報告發現胸腺殘留，是否為疾病警訊？需進一步追蹤處理嗎？-胸腔內科

請教我的檢查報告內容疑問？

黃醫師您好，因我有長期咳嗽常常覺得喉嚨有痰，看了很多診所醫生吃了很多藥都不見改善，後來到大醫院做檢查，以下報告有一點疑問是"Some remnant of thymus is noted."我查翻譯是:注意到一些殘留的胸腺請問這個會有可能是其不好的徵兆嗎? 有這種情形我需要做後續的追蹤處理嗎?也不知道會不會是我長期鼻水倒流而造成的長期咳嗽症狀，咳嗽幾乎咳整天，氣管有痰的感覺，嚴重時呼吸會有咻咻聲，晚上睡覺躺著更是不舒服很難入睡，有時候咳到胸口都有點痛了約2年前做鼻中膈彎曲手術，鼻塞狀況是解決了，但咳嗽狀況還是一樣... 甚至還被診斷疑似有空鼻症的症狀...CT報告：Some remnant of thymus. No active lung lesion.CT scan of the chest from the apex of lung to the adrenal glands with the contrast enhancement was performed and the images revealed: ＞ No active lung lesion in both lungs. ＞ No significant mediastinal lymphadenopathy is noted. ＞ Some remnant of thymus is noted. ＞ Grossly normal appearance of bilateral adrenal glands. ＞ No osteolytic or osteoblastic bone lesion is identified in visible bony structure.X光報告：＞ Normal heart size. ＞ Clear bilateral costophrenic angles ＞ Suggest clinical correlation and follow up.Standing chest PA view: ＞ The heart size is within normal limit. ＞ Apical pleural thickening at right side.驗痰報告：The specimen submitted consists of more than 10 tissue fragments measuring up to 2.8 x 1.2 x 0.3 cm in size, fixed in formalin. Grossly, they are tan to brown and soft to bony. Representative section is taken. Microscopically, it shows some fragments of cartilage tissue with focal degenerative change and mild chronic inflammatory cell infiltration in the edematous stroma. The ovrlying respiratory epithelium shows mild regenerative change. The vascular component shows congestion. The whole picture is consistent with degeneration with chronic inflammatory process. Please correlate with clinical condition and follow up.
