The Pott’s puffy tumor: a dangerous sign for intracranial complications

Pott Puffy Tumor Secondary to Cranial Vault Reconstruction in a Patient With Metopic Craniosynostosis

Pott puffy tumor (PPT) is defined as a subperiosteal abscess of the anterior wall of the frontal sinus associated with underlying frontal osteomyelitis. PPT affects all age groups but occurs predominantly in adolescents. The potential etiologies include rhinosinusitis, a history of direct trauma to the forehead, odontogenic disease, intranasal drug abuse, diabetes, or other immunocompromised states. We introduce a case of a 6-year-old boy with a medical history of anterior cranial vault remodeling presenting with localized forehead swelling. Computed tomography imaging demonstrated mucosal thickening and a region of dehiscence in the wall of the frontal sinus; the presence of midline subperiosteal abscess was consistent with a diagnosis of PPT. Due to concerns for intracranial involvement, we utilized removal and replacement of the anterior wall of the frontal sinus, complete removal of sinus mucosa, and frontal sinus obliteration with bilateral peri-cranial flaps. To the best of our knowledge, this is the first case description of a PPT secondary to cranial vault reconstruction in a patient with metopic craniosynostosis.

Pott's Puffy Tumor in Pediatric Patients: Case Series and Literature Review

BACKGROUND

Pott's puffy tumor (PPT) is a rare complication of frontal sinusitis. Although it may occur at any age, the incidence is higher during adolescence.

METHODS

We report a series of 10 pediatric patients (9-17 years of age) who presented with PPT in 2 tertiary care pediatric hospitals in central Israel between January 2018 and August 2022 and review the published literature on pediatric PPT.

RESULTS

The most common clinical presentations included headache (10 cases), frontal swelling (6 cases) and fever (5 cases). Symptom duration before admission was between 1 and 28 days (median 10 days). The diagnosis of PPT was made by imaging studies at a median of 1 day after admission. All 10 patients underwent computed tomography studies, and 6 patients also underwent magnetic resonance imaging. The overall rate of intracranial complications was 70%. All 10 children were treated with systemic antibiotics and surgical interventions. Streptococcus constellatus group was the most common causal bacteria. All 10 patients recovered uneventfully.

CONCLUSIONS

Our findings show that a high index of suspicion for PPT should be applied to adolescents presenting with prolonged headache and frontal swelling. Contrast-enhanced computed tomography is an appropriate first tool for the evaluation; however, an magnetic resonance imaging should be performed to determine the necessity of intracranial interventional treatments if there is any suspicion of intracranial involvement. Complete recovery can be expected with appropriate antibiotic treatment and surgical intervention in most of the cases.

A Systematic Review of Intracranial Complications in Adults with Pott Puffy Tumor over Four Decades

The purpose of this study is to investigate the risk factors of intracranial complications in adult patients with Pott Puffy Tumor (PPT). A systematic review was conducted of clinical studies from January 1983 to December 2022 that reported on PPT adult patients. The full-text articles were reviewed for the patients’ ages, sex, cultured organisms, surgical procedures, clinical sequalae, and underlying diseases that may affect the onset of intracranial complications in PPT adult patients. A total of 106 studies were included. Medical data were reviewed for 125 patients (94 males, 31 females). The median age was 45 years. A total of 52% had comorbidities, mostly head trauma (24.5%), sinus/neurosurgical operations (22.4%), immunosuppression conditions (13.3%), diabetes mellitus (9.1%), cocaine use (7.1%), or dental infections (6.1%). A total of 28 cultures revealed Streptococcus (22.4%), 24 contained staphylococci (19.2%), and 22 cultures contained other pathogens (17.6%). An amount of 30.4% developed intracranial complications, with the most common being epidural abscesses or empyemas (55.3%), as well as subdural (15.7%) and extradural lesions (13.2%). Age, DM, and immunosuppression conditions are significantly associated with intracranial complications (p < 0.001, p = 0.018 and p = 0.022, respectively). Streptococcus infection is associated with intracranial complications (p = 0.001), although Staphylococcus and other microorganisms are not. Surgical intervention, mainly ESS, and broad-spectrum antibiotics remain the cornerstones of treatment.

The rare presentation of a frontal mucocele complicated by a Pott’s puffy tumor and an epidural-cutaneous fistula: illustrative case

BACKGROUND

Frontal mucoceles develop due to accumulation of mucoid secretions within the frontal sinuses. They can lead to serious consequences with further expansion and destruction of the surrounding bones or infection that might spread intracranially.

OBSERVATIONS

The authors present a case of a 37-year-old male with a frontal mucocele and the rare presentation of Pott’s puffy tumor and an epidural-cutaneous fistula, as well as a literature review of previously reported cases of epidural cutaneous fistula and sinocutaneous fistula, their predisposing factors, and their management.

LESSONS

A mucocele is a benign entity that can rarely present with potentially significant complications. Open surgery is required in patients who have frontal sinus posterior wall involvement, osteomyelitis, or intracranial involvement.

Case Report: Pott's Edematous Tumor: Complicated Frontal Sinusitis - An Unremembered Diagnosis

Pott’s Puffy tumor, also called Pott’s edematous tumor (PET), is a subperiosteal abscess of the frontal bone, associated with osteomyelitis of the frontal bone. In this paper, we report the case of a 16-year-old patient who presented with headache associated with progressive forehead swelling and fever. Clinical and imaging exams pointed to the hypothesis of PET associated with brain abscess. Patient was submitted to surgical excision of the abscess and treatment of osteomyelitis, with intraoperative findings corroborating the condition. There was a good clinical-radiological recovery associated with prolonged antibiotic therapy and satisfactory follow-up after hospital. PET, which often results from an underdiagnosed or partially treated frontal sinusitis, is a condition that must be promptly recognized and directed to an adequate therapeutic approach due to the risk of serious complications that it entails.

Pott's puffy tumor: A comprehensive review of the literature

PURPOSE

Pott's puffy tumor (PPT) is a rare clinical entity characterized by osteomyelitis of the frontal bone with subperiosteal abscess collection. The frequency of reported cases of PPT in the literature has increased in recent years. Previous reviews of PPT exist primarily in the form of small, retrospective case series and anecdotal case reports. Therefore, the aim of this study is to provide the literature's largest comprehensive, up-to-date review of the essential clinical findings, diagnostic modalities, microbiologic considerations, and treatment approaches utilized in the management of PPT, both in pediatric and adult populations.

MATERIALS AND METHODS

We searched MEDLINE, PubMed, and Embase databases for English-language studies published from January 1950 through January 30, 2022. The authors reviewed all cases of PPT, focusing specifically on those describing therapeutic management of PPT. A total of 321 patients were included, consisting of 318 patients (from 216 articles) and an additional 3 adult cases from our institution.

RESULTS

PPT most often results from untreated rhinosinusitis, as well as direct head trauma, substance use, and odontogenic disease. Infections are classically polymicrobial with an anaerobe-predominant microbiome. Both CT and MRI imaging modalities are commonly obtained for presurgical assessment of sinusitis and intracranial extension. The core of treatment is an early and aggressive approach to prevent long-term complications. A significant association exists between surgical management and clinical outcomes for patients with PPT. Recent literature suggests endoscopic sinus surgery is essential for successful disease resolution.

CONCLUSIONS

PPT is an important and relatively morbid disease process that is often underrecognized and misdiagnosed at presentation due to its variable clinical presentation. Management of PPT includes both antimicrobial therapy and surgical intervention. Determination of the optimal approach depends on patient clinical features including age, history of prior endoscopic sinus surgery, and presence of intracranial involvement on presentation. An individualized, targeted, and interdisciplinary approach to the treatment of PPT is critical for successful disease resolution.

[Pott's Puffy Tumor: a need for interdisciplinary diagnosis and treatment. German Version]

Der Pott-Puffy-Tumor (PPT) stellt als bakterielle Infektion des Sinus frontalis mit subperiostaler und intrakranieller Abszessbildung eine seltene Erkrankung in der Pädiatrie dar. Nachfolgend präsentieren wir vier Fälle eines PPT, die bei zwei Kindern (6 und 9 Jahre) und bei zwei jungen Erwachsenen (17 und 19 Jahre) auftraten. Alle Patienten wurden interdisziplinär von einem Team aus Neurochirurgie, Pädiatrie, HNO-Heilkunde, Neuroradiologie und Mikrobiologie betreut. Die Antibiotikabehandlung wurde in einem Fall mit einer endoskopischen Nasennebenhöhlenoperation (FESS) und in den anderen drei Fällen zusätzlich mit einem offenen transkraniellen Zugang zur Drainage der intrakraniellen Abszessbildung kombiniert. Da der PPT im Kindesalter mit dem Befund einer intrakraniellen Abszessbildung einhergehen kann, ist eine enge interdisziplinäre Zusammenarbeit für eine erfolgreiche Behandlung dieser seltenen Erkrankung erforderlich.

Unusual Presentation of Pott's puffy tumour in a child: our recent experience and review of the literature

Pott's puffy tumour (PPT) is a rarely seen, but highly important, complication of frontal sinusitis. Early recognition followed by prompt imaging and treatment of this condition are essential to improve patient outcomes and prevent complications. This case report describes an atypical presentation of radiologically confirmed PPT in a boy who presented with a 2.5-week history of progressive frontal headache and midline frontal swelling. Flexible nasendoscopy revealed no acute findings. Prompt CT imaging confirmed the diagnosis and early surgical intervention via endoscopic approach with aggressive antibiotic therapy led to good recovery. This case highlights the need to remember PPT in assessing any child or adolescent with a new forehead swelling, with or without sinusitis symptoms. If there is strong clinical suspicion, further imaging should not be delayed. Surgical intervention should be performed as early as possible to prevent intracranial complications; antibiotics alone are not sufficient.

Pott’s puffy tumor: a need for interdisciplinary diagnosis and treatment

Pott’s puffy tumor (PPT) is an infection of the frontal sinus with subperiosteal and intracranial abscess formation and one of the rare entities in pediatrics. We present a series of four cases of PPT that occurred in two children (6 and 9 years) and in two young adults (17 and 19 years). All patients were treated by an interdisciplinary team of pediatric, neurosurgical, ENT, radiological, and neuroradiological specialists. Antibiotic treatment was combined with single endoscopic surgery in one case and combined endoscopic sinus surgery with an open transcranial approach to drain intracranial abscess formation in three cases. It is important to be aware that PPT occurs in children with the finding of intracranial abscess formation. Therefore, a close interdisciplinary cooperation for successful treatment is needed in this rare disease.

The Use of Point-of-care Ultrasound in the Diagnosis of Pott's Puffy Tumor: A Case Report

INTRODUCTION

Pott's puffy tumor (PPT) is a rare clinical disease characterized by forehead swelling from a subperiosteal abscess coupled with frontal bone osteomyelitis. It is often associated with severe complications and poor outcomes if left undiagnosed; thus, rapid recognition is crucial. Point-of-care ultrasound (POCUS) may provide an alternative pathway to diagnosis. It can be performed rapidly at the bedside and assist in early screening of patients, identifying those with high suspicion for PPT and prioritizing imaging and consultation.

CASE REPORT

A 59-yghb ar-old-male presented to the emergency department for evaluation of a "lump" on his forehead. He recently had a bifrontal craniotomy to de-bulk a polyp burden in an effort to manage his recurrent sinusitis. To further characterize the mass, a POCUS examination was performed by the treating emergency physician. The examination found a subcutaneous, hypoechoic fluid collection extending superficially along the frontal bone. A discontinuity in the surface of the frontal bone was visualized through which the collection appeared to extend. Given the heightened concern for PPT based on the POCUS examination findings, otolaryngology service was consulted and the patient was admitted for further imaging and treatment.

CONCLUSION

Pott's puffy tumor is a rare diagnosis that has the potential for life-threatening complications. Timely diagnosis is imperative. Point-of-care ultrasound can easily be used to help identify patients with suspicion for PPT in the acute care setting and influence patient management with regard to obtaining further imaging and plans for early consultation.

Pott's puffy tumor: as a very rare and unpredicted complication of ipsilateral pan sinusitis - case presentation and review of articles

Pott's puffy tumor is considered as a rare clinical entity. It is developed as a rare complication of frontal sinusitis. In addition, the trauma to the frontal area is another suggested cause. The Pott's puffy tumor is presented as a forehead swelling due to sub-periosteal collection. Although, the Pott's puffy tumor is a rare condition but at the same time, it can be serious because it may lead to life threatening complications namely, extradural abscess, subdural abscess, meningitis, encephalitis, and brain abscess. Thus, the Pott's puffy tumor is classified as a very significant surgical emergency.

Pott's puffy tumor in a 23-month-old: Youngest known case of a rare disease

This case report describes a child who developed Pott's puffy tumor and was treated at the Children's Mercy Hospital in Kansas City. In addition to a discussion of a case, a review of the literature was completed on this topic describing the typical embryology and development of the frontal sinus, and the epidemiology, diagnosis, and treatment of Pott's puffy tumor. The patient was a 23-month-old boy who developed Pott's puffy tumor after recovery from influenza. The patient presented to the hospital with progressing edema of the unilateral eye that spread bilaterally within a few days. A CT scan demonstrated pansinusitis, developed frontal sinuses, right periorbital cellulitis, and medial forehead subperiosteal abscess. Functional endoscopic sinus surgery and transcutaneous abscess drainage were urgently performed and the patient made a full recovery following a course of ertapenem and levofloxacin. The presence of a developed frontal sinus in a 23-month-old is an unexpected radiologic finding. This case represents the youngest patient reported in the literature to develop this rare complication of frontal sinusitis.

A Case of Pott's Puffy Tumor Associated With Barosinusitis From Scuba Diving

ABSTRACT

Barosinusitis, or sinus barotrauma, is a well-described condition associated with changes in barometric pressure during flight and diving that can result in sinonasal mucosal injury. In this case report, we present an adolescent who experienced barosinusitis during scuba diving and subsequently developed Pott's puffy tumor (PPT), characterized by frontal sinusitis, frontal bone osteomyelitis, and overlying subperiosteal abscess. This unique case of PPT following scuba diving provides the opportunity to review the pathophysiology of both barotrauma-induced sinus disease and PPT, a rare and unreported serious complication of barosinusitis. Furthermore, we discuss how scuba diving and associated barosinusitis can be considered a risk factor in the development of PPT.

Pott Puffy Tumor in Adults: The Τiming of Surgical Ιntervention

Pott’s puffy tumor (PPT) represents a rare complication of frontal sinusitis, and it is considered as a subperiosteal abscess of the frontal bone based on osteomyelitis.

We report two adult PPT patients and discuss the treatment plan as well as the correct timing of surgical intervention. Clinical examination revealed sinusitis with puss, and imaging findings showed bony erosion of the dorsal wall of the frontal sinus in both patients. In case 1, a “wait and see” approach was followed with remission of the patient’s symptoms, and a Draf IIb type was performed 21 days after discharge. In case 2, worsening of symptoms led to surgical drainage through a Lynch incision followed by 20 days of intravenous antibiotic treatment. Then a Draf type IIa was performed. Both patients received antibiotic therapy over the course of six weeks and had full recovery.

We highlight the importance of the correct timing of surgical intervention as it is depended on the clinical and radiological findings. The timing to performing radical drainage surgery including external or endoscopic frontal sinus surgery is not determined in the literature. Worsening of common symptoms and neurological signs in adult PPT patients means by default an immediate surgical intervention. Reduction of symptoms and antibiotic treatment response means that surgery should be delayed and performed in a surgical field free of inflammation.

Pott's puffy tumor caused by Actinomyces naeslundii

Pott’s puffy tumor is characterized by forehead swelling from subperiosteal abscess and frontal bone osteomyelitis. It is encountered mainly in children; rarely in adults. When it does occur in the latter population, the most common risk factors include head trauma, sinusitis, or cocaine abuse. Generally, the organisms thought to be involved include streptococci, staphylococci and oral anaerobic flora. We present a case of a 53 year old female who presented with forehead swelling of 3 month duration after a dental procedure, found to be secondary to Actinomyces naeslundii. Actinomyces is a very rare etiology of this disease and has been reported only twice earlier in the literature. We present an uncommon infectious disease along with summary of clinical characteristics of this entity in the adult population.

Pott's Puffy Tumor: Intracranial Extension Not Requiring Neurosurgical Intervention

Pott’s puffy tumor, typified by a subperiosteal abscess underlying the frontal bone, is an uncommonly encountered clinical entity that can occur in the setting of local trauma or secondary to frontal sinusitis. Diagnosis can be challenging, as cultures may be sterile, and the condition must be differentiated from neoplasm and superficial and soft tissue infection. Although more common in the pediatric population, Pott’s puffy tumor must remain on the differential with a high index of suspicion in adult patients who fit the clinical picture. Early diagnosis with CT or MRI and therapeutic medical and surgical intervention are crucial as intracranial complications, such as abscess and empyema can occur and may be fatal. We present an adult patient with a history of inhaled drug abuse who presented with Pott’s puffy tumor with meningitis and bifrontal epidural abscesses at presentation. There is evidence in the literature that management of sinus-related intracranial epidural abscess with antibiotic therapy and adequate surgical or endoscopic surgical drainage may bypass the need for neurosurgical intervention, as was the case here.

Draf III frontal sinus surgery for the treatment of Pott's puffy tumour in adults: our case series and a review of frontal sinus anatomy risk factors

Purpose

We present our case series of four adult patients with Pott’s puffy tumour (PPT), successfully treated with Draf III over a mean period of 11 months. A critical review of the literature is also provided.

Methods

A retrospective review of patients undergoing Draf III for PPT from January 2018 to January 2019 was performed.

Results

Four consecutive male patients ranging from 26 to 62 years, with a mean age of 49.5 ± 16.3 years, undergoing Draf III for Pott’s puffy tumour were included. Two patients had a Kuhn type IV frontal cell narrowing the frontonasal pathway and presented without previous sinus surgery, whereas the other two had previous sinus surgery. The success rate of the operation was 100% with an average length of follow-up of 11 months (range 5–18).

Conclusion

In our experience, the Draf III procedure is a highly effective treatment of PPT. In particular, we have demonstrated it to be very effective in accessing highly positioned Kuhn type IV cells.

Treatment of pediatric extra-axial sinogenic infection: case series and literature review

PURPOSE

Analyze the clinical presentation, microbiology, outcomes, and medical and surgical treatment strategies of intracranial extension of sinogenic infection in pediatric patients.

METHODS

A retrospective, single-center study of patients < 18 years of age, presenting with intracranial extension of bacterial sinogenic infections requiring surgical intervention over a 5-year period, was conducted. Electronic medical records were reviewed for age, sex, primary symptoms, duration of symptoms, presence of sinusitis at initial presentation, microorganisms isolated, mode of surgery, timing of surgery, length of stay, and neurologic sequelae.

RESULTS

Seventeen patients were identified; mean age was 10 years with 82.3% male predominance. Average duration of illness prior to presentation was 9.8 days, with 64.7% of patients displaying disease progression while on oral antibiotics prior to presentation. Sinusitis and intracranial extension were present in all patients upon admission. Simultaneous endoscopic endonasal drainage and craniotomy were performed on 70.5% of the patients, with the remaining 29.5% undergoing endonasal drainage only. Of the patients who underwent simultaneous endoscopic endonasal drainage and craniotomy, 17.6% required repeat craniotomy and 5.8% required repeat sinus surgery. The most commonly isolated organisms were S. intermedius (52.9%), S. anginosus (23.5%), and S. pyogenes (17.6%). All patients were treated postoperatively antibiotic on average 4-6 weeks. Frequently occurring long-lasting complications included seizures (29.4%) and focal motor deficits (17.6%); learning disability, anxiety disorders, impaired cognition, and sensory deficits occurred less frequently.

CONCLUSION

In the case of intracranial extension of bacterial sinogenic infection, early identification and surgical treatment are crucial to avoid neurological sequelae.

Orbital abscess as a complication of Pott's puffy tumour in an adolescent male

Pott's puffy tumour (PPT) is a known complication of frontal sinusitis. It is defined as subperiosteal abscess formation due to osteomyelitis of the frontal bone presenting as a forehead swelling. It is a life-threatening condition that can lead to intracranial and intraorbital complications. Gadolinium-enhanced MRI and contrast CT scan are the best modalities to localise and define the collection, in addition to confirming disease extension. Once confirmed by imaging and depending on disease extension, management of PPT requires a multidisciplinary team approach and depends on the local provision of surgical care. Following surgical drainage of the abscess cavity, a prolonged course of antibiotics is required postoperatively to treat the underlying osteomyelitis.

Pott's puffy tumor in children: A review of the literature

OBJECTIVES

Pott's puffy tumor (PTT) is a frontal subperiosteal abscess associated with underlying frontal osteomyelitis. The purpose of the present study was to assess the rate of intracranial involvement in pediatric and adolescent patients with PPT and to discuss the diagnostic workup and the therapeutic features of this pathology.

METHODS

We searched Web of Science, PubMed and MEDLINE from 1998 to 2018. The search focused on papers concerning the diagnostic procedure and therapeutic management of PTT. Statistical techniques were not used.

RESULTS

We included 53 articles that described 92 pediatric and adolescent patients with PPT. The overall rate of intracranial complications was found to be 72%. Most authors used computed tomography for the diagnosis of PTT and its complications, either alone or in combination with magnetic resonance imaging. In 50% of cases, an endoscopic endonasal approach is used for the management of the underlying acute or chronic sinusitis.

CONCLUSIONS

On the basis of the available literature, it seems that the incidence rate of intracranial involvement in patients with PPT is quite high. Early diagnosis using the appropriate imaging raise the possibility of good recovery. Concerning the therapy of PTT, endoscopic sinus surgery could be considered as a valuable technique. The vast majority of patients treated appropriately recover without long-term neurologic complications and sequelae.

Pott puffy tumor

Pott puffy tumor is osteomyelitis of the frontal bone with associated subperiosteal abscess causing swelling and edema over the forehead and scalp. It is a complication of frontal sinusitis or trauma. We present the case of an 8-year-old girl with frontal swelling. Imaging evaluation showed frontal osteomyelitis as a complication of frontal sinusitis with associated epidural and subperiosteal abscess. The patient was treated surgically and recovered well. This case highlights the need for high clinical suspicion and early diagnosis and management to prevent life-threatening complications. Unfortunately, in our case the patient had to undergo surgery for this complication, which could have been prevented by earlier diagnosis.

Pott Puffy Tumor in Children: A Rare Emergency Clinical Entity

OBJECTIVES

Pott puffy tumor (PPT) is defined as soft tissue swelling of the forehead due to subperiosteal edema, accumulation of pus, or granulation tissue. It is associated with osteomyelitis of frontal bone secondary to frontal sinusitis. Pott puffy tumor can be complicated by preseptal and orbital cellulitis and intracranial infection.

METHODS

Six patients diagnosed with and treated for PPT in Pediatric Clinic of Uludag University Faculty of Medicine from 2010 to 2015 were reviewed retrospectively. Age, sex, presenting symptoms and signs, laboratory and radiological findings, as well as intracranial complications and treatment modalities of all patients were evaluated.

RESULTS

The authors present 6 pediatric patients of PPT, 5 males and 1 female with a mean age of 11 years (age range, 7-18 years). All patients presented with headache, fever, and tender frontal swelling. Two of the patients had epidural abscess and 1 had preseptal orbital cellulitis in addition to PPT. All of them had computed tomography scan and/or magnetic resonance imaging. Endoscopic sinus surgery was performed in 4 patients and 2 patients underwent neurosurgical intervention with antibiotherapy.

CONCLUSIONS

Pott puffy tumor may be associated with potentially dangerous intracranial complications. Early diagnosis and treatment are essential to reduce morbidity and mortality. Imaging plays an important role in the diagnosis of the disease and the detection of its complications.

Patient presenting with frontal subperiosteal abscess and headache: a case of Pott's puffy tumour

Chronic sinusitis can be complicated with erosion of anterior or posterior wall of the sinus; causing Pott's puffy tumour in the anterior, or epidural abscess in the posterior communication. A 65-year old man with a painful swelling in his forehead is presented. Pott's puffy tumour was diagnosed. CT, MRI, and DTI studies were obtained. Epidural or dural involvement was not present. In the first operation, anterior wall of the frontal sinus wall was opened. Osteomyelitis debridement was performed and the frontonasal duct was enlarged endoscopically. Antibiotics were commenced and were continued for 6 weeks. In the second operation, nasal septum deviation was fixed. Postoperative course was uneventful. The presented case suggests that treatment of sinus osteomyelitis should comprise immediate surgical drainage and osteomyelitis debridement followed by long-term administration of antibiotics. MRI study with contrast should be obtained to rule out epidural abscess and dural infiltration.

A Pott's Puffy Tumor Associated with Epidural - Cutaneous Fistula and Epidural Abscess: Case Report

Background:

Pott’s puffy tumour is characterized by a fluctuate swelling of the frontal region as a result of osteomyelitis of the frontal bone. This inflammatory lesion may propagate endocranially, resulting in acute meningitis, epidural abscess, subdural empyema, cavernous sinus trombophlebitis, cerebritis, and frontal lobe abscess of the brain.

Case Report:

We present an unusual case of a 33-year-old man suffering from Pott’s puffy tumour whose condition was further complicated by a draining epidural-cutaneous fistula and an epidural abscess. We confirmed the diagnosis by contrast-enhanced computed tomography scanning and magnetic resonance imaging of the head. After intense antibiotic treatment, we performed a combined endoscopic and external surgical approach with drainage of abscesses, evacuation of pus and bone sequestrate and excision of fistulous lesion. The treatment was prolonged with four weeks’ antibiotic administration.

Conclusion:

Subperiosteal abscess of the frontal bone is an extremely rare complication of frontal sinusitis. This lesion may propagate endocranially, resulting in dangerous intracranial inflammatory lesions. Early diagnosis, medication and surgical therapy are very important in reducing morbidity and mortality.

Minimally Invasive Surgery for Pott's Puffy Tumor: Is It Time for a Paradigm Shift in Managing a 250-Year-Old Problem?

INTRODUCTION

The aim of this study was to review the clinical outcomes and efficacy of endoscopic sinus surgery (ESS) in the management of Pott's puffy tumor (PPT).

METHODS

Literature PubMed review using a combination of MeSH terms and keywords was undertaken, combined with a single surgeon case series of 3 patients.

RESULTS

A total of 29 (20 males, median age 25 years) cases were reviewed. The most common etiology was acute frontal sinusitis (62%), followed by a history of chronic rhinosinusitis (28%). Two patients presented with concomitant preseptal cellulitis and cutaneous fistula each, while another had pneumocephalus. The majority of cases (59%) had Draf 1 procedure. Three cases had Draf 3 procedure. Five cases were successfully treated by sinus balloon sinuplasty. Postoperatively, most patients had either oral or intravenous antibiotics of varying duration. There were no further complications following ESS. Both fistulas healed without requiring surgical debridement or closure.

CONCLUSION

Some PPT cases can be managed endoscopically. The availability of powered angled instruments, high-definition video, and image guidance systems have provided the modern otolaryngologists with a credible alternative to traditional techniques. Furthermore, improved bioavailability of modern antibiotics may obviate the need for craniotomy and external drains.

Intracranial Suppurative Complications of Sinusitis

BACKGROUND

Intracranial complications of paranasal sinusitis have become rare due to widespread and early use of antibiotics. Potentially life-threatening intracranial complications of sinusitis include subdural empyema, epidural and intracerebral abscess, meningitis, and sinus thrombosis. Patients with intracranial complication of sinusitis can present without neurological signs, which may delay diagnosis and correct treatment.

AIMS

Our aim was to evaluate the diagnostics, treatment, and outcome of sinusitis-related intracranial infections at our tertiary referral hospital with a catchment area of 1.9 million people.

MATERIALS AND METHODS

We retrospectively collected data on all patients diagnosed and treated with an intracranial infection at the Helsinki University Hospital, Helsinki, Finland, during a 10-year period between 2003 and 2013.

RESULTS

Six patients were diagnosed to have a sinusitis-related intracranial infection. Four patients had an epidural abscess, one both an epidural abscess and a subdural empyema and one a subdural empyema. The most common presenting complaint was headache (100%) followed by fever (83%), vomiting (50%), nasal congestion (50%), forehead lump (34%), and neck stiffness (17%). All patients were managed surgically. Most (83%) patients recovered to premorbid state without neurological sequelae. One patient died intraoperatively.

CONCLUSION

Patients with a sinusitis-related intracranial suppuration typically present with signs of raised intracranial pressure rather than signs of sinusitis. Most are likely to need neurosurgical intervention and evacuation of the abscess without delay.

Acute Frontal Sinusitis

Uncomplicated acute frontal sinusitis (AFS) is most often associated with an antecedent viral upper respiratory tract infection. Bacterial infection is suspected if symptoms are persistent for at least 10 days.

Comprehensive review on endonasal endoscopic sinus surgery

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

Pott's puffy tumor: a rare complication of acute otitis media in child: a case report

To describe a rare case of Potts' puffy tumor (PPT) in the zygomatic area, which developed as a complication of acute otitis media in a 6-year-old child. To date, only one case of PPT has been described in the literature as a complication of latent mastoiditis in an adult, and one case of PPT as a complication of acute mastoiditis in a 10-year-old child. Urgent surgical intervention, including evacuation of the purulent lesion, removal of inflamed soft tissue and osteolysis of the involved bone, and antromastoidectomy, intravenous treatment with broad-spectrum antibiotics, including G+, G-, anaerobes and fungi, and local therapy.

Pott's puffy tumor in a 12-year-old boy

Pott's puffy tumor (PPT) is a rare complication of sinusitis characterized by subperiosteal abscess and osteomyelitis of the frontal bone. Early diagnosis and treatment is vital before it causes intracranial complications such as subdural empyema or brain abscess. Herein we describe the case of a 12-year-old patient who developed preseptal cellulitis and PPT, and was successfully treated with abscess drainage, sinus surgery and long-term antibiotic therapy.

Neurosurgical implications of Pott's puffy tumor in children and adolescents

INTRODUCTION

Pott's puffy tumor (PPT) is rare and usually seen as a complication of frontal sinusitis resulting in subperiosteal abscess of the frontal bone with underlying osteomyelitis. PPT is potentially severe and can lead to life-threatening intracranial complications.

PATIENTS AND METHODS

The authors present a series of six pediatric patients diagnosed with PPT and intracranial complications between 1999 and 2012. There were five boys and one girl, and the mean age at diagnosis was 11.8 years. All patients presented with frontal swelling, headache, and fever. Two patients had lowered level of consciousness and severe hemodynamic instability.

RESULTS

All patients had epidural abscess, and one also presented subdural empyema. Five patients underwent drainage of all associated abscesses, bone resection, and sinusitis treatment. One was treated conservatively with broad-spectrum antibiotics, and no surgical intervention was required. All patients fully recovered their neurologic status, without further complications.

Extensive Frontoparietal Abscess: Complication of Frontal Sinusitis (Pott's Puffy Tumor)

First described in 1768, the Pott's puffy tumor is a subperiosteal abscess associated with frontal bone osteomyelitis, resulting from trauma or frontal sinusitis. The classic clinical presentation consists of purulent rhinorrhea, fever, headache, and frontal swelling. The diagnosis is confirmed by CT scan and treatment requires intravenous antibiotics, analgesia, and surgical intervention. Early diagnosis and aggressive medical and surgical approach are essential for a good outcome. It rare and the early diagnosis is important; we describe the case of a 14-year-old adolescent with Pott's puffy tumor who was initially treated inadequately, evolving with extensive frontoparietal abscess. The patient underwent surgical treatment with endoscopic endonasal and external approaches combined. Intravenous antibiotics were prescribed for a prolonged time, with good outcome and remission of the complaints.
