“…The diminished growth of ultimobranchial body on the right side may also contribute for the same. This asymmetry also supports the embryological origin of PSF, which follows the course similar to the recurrent laryngeal nerve [3].…”

“…In cases of acute presentation as an inflammatory mass, broad-spectrum antibiotics are administered as infecting organisms are from the oral flora [2]. Incision and drainage of the abscess may be required if non responsive to antibiotic therapy [3]. The culture of the abscess in majority of our patients grew streptococcal species that were sensitive to penicillin and ampicillin.…”

“…Nonetheless, the persistence of third or fourth pharyngeal pouch as the pyriform sinus fistula can lead to thyroid abscesses due to the common embryological origin [2][3][4][5][6][7]. Pyriform sinus fistula is the least common branchial apparatus malformation and AST resulting due to its occurrence has been reported as anecdotal case reports or short case series in the literature.…”

Acute suppurative thyroiditis in children secondary to pyriform sinus fistula

Acute suppurative thyroiditis (AST), a potential complication of pyriform sinus fistula (PSF), is a rare clinical condition as the thyroid gland is remarkably resistant to infections. Lack of awareness of the entity contributes to the rarity and frustrating recurrences. We performed a retrospective review of all cases of AST due to PSF treated at our institution over a 10-year period. The clinical data, investigations, operative findings and procedures, microbial culture reports and follow-up were recorded and analyzed. Between January 1997 and September 2006, 12 cases (8 males and 4 females) of AST due to PSF were treated. Nine patients (75%) underwent successful complete excision, seven of whom had initial incision and drainage procedures. In three patients (25%) with recurrence, one underwent complete excision at a later procedure, one patient had multiple recurrences with six incision and drainage procedures and two failed attempts of excision of PSF before final successful complete excision. The third patient is awaiting re-excision of the PSF tract. All patients, except the one awaiting re-excision, are well with no further recurrences during the follow-up period that ranged from 18 to 96 months (median, 46.5 months). AST due to PSF is a challenging entity in terms of diagnosis and management as recurrences are common despite meticulous dissection. High index of suspicion and radiological investigations such as barium studies and computed tomography scan aid in the delineation and excision of the fistulous tract.

“…These abnormalities often occur as tracts from the piriform sinus to the thyroid gland and are sometimes referred to as piriform sinus fistulas [1]. Nevertheless, these two types of anomalies are anatomically distinct: third branchial arch anomalies are proposed to originate from the base (cranial end) of the pyriform sinus and pass above the superior laryngeal nerve, whereas the tract of fourth branchial arch anomalies originates from the apex (caudal end) of the pyriform sinus and passes through the cricothyroid membrane beneath the superior laryngeal nerve [19]. Embryologically, the third branchial pouch creates the thymus and the inferior parathyroid glands [10], whereas the fourth arch originates the following structures: cricopharyngeal, inferior pharyngeal constrictor and cricothyroid muscles; cuneiform and thyroid cartilages; superior laryngeal nerve; aortic arch and right subclavian artery; superior parathyroid glands and thymus [20] (Fig.…”

“…2 The most common mechanism of thyroid infection is transmission of an infection via a pyriform sinus fi stula [3][4][5][6] : an underlying congenital anomaly extending from the apex of the hypopharynx to the thyroid gland. 7,8 Less frequent causes of thyroid abscess include the direct spread of an infective micro-organism and hematogenous or lymphatic spread from a distant infected organ. 5 We report the case of a thyroid abscess yielding a single microbial isolate, believed to have come from a pulmonary infection in a 52-year-old man.…”

Thyroid abscess is a rare clinical entity, usually associated with a pyriform sinus fistula. A prompt diagnosis is important because it may progress rapidly into a life-threatening condition. We report a very unusual case of thyroid abscess associated with a lung infection, both caused by Klebsiella pneumoniae. The patient was treated successfully with a culture-appropriate antibiotic and an uneventful thyroid lobectomy. A delay in diagnosis of morbidities associated with a thyroid abscess may result in rapid exacerbation of this condition; therefore, prompt and appropriate treatment is mandatory for a successful outcome.
