Cystic metastases of the neck from occult thyroid adenocarcinoma.

In 9 of 118 patients with differentiated thyroid carcinomas, a solitary cystic lateral cervical mass simulating a branchial cleft anomaly was the sole presenting sign of the disease. These masses were nodal metastases of occult papillary adenocarcinoma of the thyroid that underwent liquefaction necrosis. Sonographically, the masses presented a complex pattern. Accordingly, it is suggested that, in patients presenting with an asymptomatic solitary lateral cystic cervical mass, the possibility of metastasis from an occult thyroid malignancy should be considered, and consent for definitive surgery should be obtained. The ultrasonic pattern of the cystic mass is of importance in the differentiation of a cavitated lymph node from a branchial cleft cyst.

Central nervous system complications secondary to oto-rhinologic infections. An analysis of 39 pediatric cases.

Fifty-eight central nervous system complications were noted in 39 pediatric patients with a primary oto-rhinological infection. The ages ranged from 1 to 15 years. Eleven patients (25%) had more than one complication. 12.8% of the cases died. Leptomeningitis was the most common intracranial complication (54%) Lateral sinus thrombosis (LST) occurring in 10 patients (26%) was accompanied with other intracranial abnormalities in 80% of cases. Brain abscess as an initial or concomitant complication was associated with the highest mortality rates (40%). In two of these fatal cases multiple brain abscesses were detected. The low incidence of intracranial infections secondary to oto-rhinologic infections and the masking effect of antibiotics present difficulties in the early recognition of the CNS complication. Despite the value of the modern imaging techniques in the investigation of the CNS complication, the clinical oto-rhinologic examination is of paramount importance in detecting the original infection in the pneumatic spaces of the upper respiratory tract. Additionally, bone scans were found of value in demonstrating the osteitic process of these cases.

Osteoblastic osteitis of the maxillary sinus.

Osteoblastic osteitis is a rare kind of bone infection typified by a proliferative reaction of the periosteum and by exuberant bone formation. In the maxillary sinus, it occurs as a consequence of chronic or recurrent sinusitis. It usually manifests with a vague facial discomfort, followed by complications in the deep facial spaces or fossae. The diagnosis is a radiological one. Eradication of this bone infection necessitates removal of the precipitating condition as well as the long-term administration of appropriate anti-biotics. In the case of a deep facial fossae abscess, drainage is mandatory.

Early treatment of orbital floor fractures with catheter balloon in children.

Fifteen pediatric patients with orbital floor fractures were successfully treated early, following injury by a transantrally introduced catheter-balloon technique. The latter stabilizes and supports the torn, but still vascularized periosteum at the edges of the fracture and also serves as a guide for its further proliferation and new bone formation. Apart from a transient anesthesia in the dermatome of the infraorbital nerve in certain patients no complication or sequela was noted in this series. Accordingly early repair with the use of catheter-balloon appears to be a viable alternative in the repair of orbital floor fracture in children.

Air cyst of the maxillary sinus (pneumosinus dilatans, pneumocoele).

A cystic dilatation of a paranasal sinus by an entrapped air mass has been termed pneumosinus dilatans or a pneumocoele. The occurrence of this condition in the maxillary sinus is quite rare. In the present case, a mid-face mass mimicking an osteoma was the presenting sign of the disease. The pathogenesis, clinical features and radiological aspects of this entity are reviewed. In order to avoid confusion with other conditions of different aetiopathogenesis, we propose to label the lesion as 'air cyst' of the paranasal sinus, a term that best describes the nature of the lesion.

Giant cervical cyst: presenting symptom of an occult thyroid carcinoma.

A case of giant lateral cervical cystic metastasis from occult thyroid carcinoma mimicking branchial cleft cyst is reported. Lateral cervical cystic metastases arising from occult thyroid carcinoma and their ultrasonic differentiation from true cysts are discussed.

Salmonella neck abscess associated with jugular vein thrombosis.

An unusual case of synergistic infection caused by Salmonella paratyphi and anaerobic streptococcus resulting in necrotizing cervical infection associated with deep neck abscess and internal jugular vein thrombosis, is presented. Salmonella acting as an oxygen consumer in the infected tissues, facilitates the growth of anaerobic cocci, hence the development of a devastating soft tissue infection. The precipitating cause was a tonsillar infection developing due to 'post-anginal sepsis'. The aetiopathogenesis of the cervical infection is discussed.

C.T. demonstration of metastatic anaerobic orbital abscess.

Orbital abscess of rhinosinogenic origin may develop, either by contiguous spread of the infection or by a thrombophlebitic process. While destruction of the bony walls of the paranasal sinus occurs in propagation of the infection by tissue continuity, haematogenous spread may take place through intact bone. Computed tomography demonstrates the status of the bony partitions shared by the orbit and paranasal sinuses, and the source of the orbital sepsis, thereby influencing the therapeutic approach.

Necrotizing soft-tissue infections in the head and neck: a clinicopathological study.

The clinicopathological aspects of 15 patients with necrotizing soft-tissue infections in the head and neck are reviewed. Our relatively large series suggests that the disease occurs more frequently than described in the literature. Histological studies showed that tissue superficial and deep to the fascia is frequently involved with the infectious inflammatory process, even in early stages of the disease. These pathologic changes were also found in healthy-appearing tissues at the periphery of the lesions. The early recognition of the disease and the prompt and aggressive surgical and medical therapeutic approach have resulted in far lower mortality rates (7%) than those reported in the literature. Frozen-section examination contributed to the maximal eradication of the pathologic process. This successful outcome was achieved in spite of the adverse associated clinical conditions, such as old age, debilitating disease, or complications, observed in half of the patients.

Infections of the infratemporal fossa: imaging/clinical correlations.

While infections of the infratemporal fossa are occasionally documented in the otolaryngologic literature, a recent computer literature search failed to identify any significant series of cases describing this potentially fatal infection. This presentation focuses attention on the joint clinical/imaging experience of 11 cases of infratemporal fossa infection, as seen at the Soroka Medical Center of the Ben Gurion University of the Negev, in Beer-Sheva, Israel, and the Mount Sinai Hospital, of the University of Toronto, in Toronto, Canada. This manuscript reviews our experience, with particular emphasis on the effective role and accuracy of CT scanning in identifying the correct anatomic and pathologic diagnosis, as well as in the planning of treatment.

CNS complications of ear, nose and throat infections: an analysis of 50 consecutive cases.

Sixty-four diverse central nervous system (CNS) complications were noted in a series of 50 patients initially suffering from an otorhinological infection. Thirty-five patients (70%) were in pediatric age groups (1-15 years). Twelve patients (24%) had more than one complication. Mortality rates were 16% in patients with one CNS complication and 25% in patients with multiple complications. Overall mortality rate was 18%. Leptomeningitis was the most common intracranial complication (42%) occurring, mainly in pediatric patients. Lateral sinus thrombosis (LST) was accompanied with other intracranial abnormalities in 72% of the cases. Brain abscess as an initial or concomitant complication was associated with the highest mortality rates (44%). Three of these fatal cases had multiple brain abscess. The rarity of intracranial suppurations secondary to ear and nose infections and the masking effect of the antibiotics bring difficulties in the early detection of CNS complications. Although the modern imaging techniques contribute to the recognition and localization of the intracranial pathology, the clinical investigation is still of paramount importance in detection of the original infection in the pneumatic spaces of the upper respiratory tract.
