Pott\'s puffy tumors are assumed to be infrequent concomitant intra- and extracranial abscesses, mainly secondary to complicated frontal sinusitis during infancy. Due to the close proximity to the superior sagittal sinus, there is a risk of developing venous infections, thrombosis, and morbidity. In this case report, we present a case of an 11-year-old girl who presented with headache and face edema. After recognizing the Pott\'s puffy tumor pattern on the CT scan and brain MRI, the neurosurgical approach involved pus evacuation and frontal sinus blockage, and the patient received antibiotic therapy and was evaluated for total recovery. To our knowledge, the prompt diagnosis and treatment of such conditions are paramount to avoid complications, and differential diagnosis should be encouraged in medical practice.

Eosinophilic chronic rhinosinusitis (ECRS) is a refractory type 2 inflammation-based airway allergic disease that is prone to complications such as bronchial asthma. Pott\'s puffy tumor (PPT) is a rare clinical entity characterized by osteomyelitis of the frontal bone accompanied by a subperiosteal abscess. A 56-year-old female with a history of cranial surgery and bronchial asthma presented to an otolaryngology clinic with nasal obstruction and loss of smell, later developing swelling and redness on her forehead. She was diagnosed and treated for ECRS and was thought to have developed PPT during her course. Nasal endoscopy reveals bilateral polyp formation originating from the middle meatus. Paranasal computed tomography (CT) indicates substantial swelling extending from the opening of the frontal sinus to the adjacent subcutaneous tissue, accompanied by a defect in the frontal bone and osteolysis at the base of the frontal skull. Her management included conservative antibiotic therapy adjusted due to a drug eruption and, subsequently, endoscopic sinus surgery (ESS). The case was complicated by the patient\'s medical history and the absence of detailed surgical records, which limited the use of enhanced imaging techniques. This underscores the complexity of diagnosing and managing PPT in adults, particularly those with prior surgeries, emphasizing the need for a tailored diagnostic and therapeutic approach that integrates detailed patient history with current clinical indicators to effectively guide treatment. This case contributes to the limited literature on adult PPT and underscores the critical need for careful patient monitoring and detailed surgical history.

Pott\'s puffy tumor (PPT) is a rare but life-threatening complication of chronic sinusitis, although it can be secondary to other entities such as trauma or insect bites. It is characterized by circumscribed frontal swelling associated with a subperiosteal abscess. Imaging plays a crucial role in diagnosis and early identification of complications, some of which can be life-threatening, including intracerebral and intra-orbital complications. We present a case of a 14-year-old male with non-specific frontal pain and swelling, where the diagnosis of PTT was confirmed through imaging studies. Upon admission, the patient exhibited orbital and intracerebral complications, as shown in MRI and CT scans. Treatment involved a combination of antibiotics and sinus surgery, with close monitoring for orbital and intracranial complications.

UNASSIGNED: To describe clinicoradiological features and surgical outcomes in a series of nine patients with rhino-orbito-cerebral mucormycosis (ROCM) who presented with Pott\'s puffy tumor (ROCM-PPT).
UNASSIGNED: The records of nine patients with ROCM-PPT seen between March 2020 and December 2021 were analysed. Clinical features, radiology, histopathology, operative findings, management and outcome were noted. Frontal sinus pneumatisation and outflow tract configuration was compared between patients and controls with ROCM and no PPT.
UNASSIGNED: ROCM-PPT was diagnosed in 9 of 284 (3.2 %) patients with ROCM seen during the study period. There were six (66.7 %) males and the median age was 54 (IQR 46-60) years. Eight (88.9 %) patients had diabetes mellitus and seven (77.8 %) had been COVID-19 positive. Radiological features of osteomyelitis, subperiosteal abscess formation and dural enhancement were seen in all patients. No significant differences in pneumatisation or frontal sinus outflow tract configuration were noted between patients and controls. All patients underwent a craniectomy with frontal bone debridement and frontal sinus exteriorisation. All patients were treated with anti-fungal agents for several months. All patients had symptomatic improvement at a median follow-up of 21 (IQR 18-23) months. Repeat CT/MRI scans showed disease regression/resolution in six out of eight (75 %) patients with follow-up imaging, and stable disease in two others.
UNASSIGNED: ROCM-PPT is a rare, delayed complication of mucormycosis that was seen in larger numbers during the recent COVID-19 pandemic. Aggressive debridement of osteomyelitic bone and antifungal therapy results in a good outcome.

Objective:To explore the characteristics and therapeutic strategies of Pott\'s puffy tumor（PPT）. Methods:The clinical data of two patients with PPT were retrospectively analyzed and combined with the literature, focusing on the comprehensive analysis of perioperative diagnosis and treatment strategies. Both patients underwent muti-disciplinary treatment, including timely administration of sufficient antibiotics capable of penetrating the blood-brain barrier. Early removal of PPT lesions was performed using a combined internal and external approach under nasal endoscopic guidance. Results:After standardized perioperative management, the symptoms of the two patients were completely relieved, with no recurrence after one=year follow=up. Postoperative complications such as frontal pain, numbness, local depression, or scar hyperplasiawere not present. Conclusion:PPT, being relatively rare and severe, requires careful attention. Key strategies for standardized perioperative management include multi-disciplinary consultation, timely and adequate antibiotic administration, and surgical intervention using a combined intranasal and extranasal endoscopic approach for lesion removal.

An abscess is a collection of pus secondary to an immune response to a pathogen. It can occur anywhere in the body, with the skin as the most common organ involved. A lip abscess is a rare condition. Generally, it may be due to an infective agent such as a virus or bacteria entering through a skin wound, or through hematogenous spread when there is a severe underlying condition such as a general condition disorder or immunodeficiency. It requires hypervigilance during the examination and throughout the treatment course with intravenous antibiotic therapy and urgent surgical drainage, as it may cause significant complications regarding localization, lymphovascular drainage, and ultimate spread. Persistent abscess, necrotic tissue, or cavitated lesions are worrisome and it is important to rule out immunosuppression or a methicillin-resistant staphylococcus. In this case, a 22-year-old male patient with a unilateral lip abscess, misdiagnosed as an allergic food reaction, responded well to external drainage and antibiotic therapy.

UNASSIGNED: Pott\'s puffy tumor is a rare condition primarily occurring in the younger population. This report highlights the clinical suspicion and diagnosis of Pott\'s puffy tumor in those presenting with favorable presentations, especially adolescents.
UNASSIGNED: Pott\'s puffy tumor (PPT) is characterized as frontal bone subperiosteal abscess and osteomyelitis, a rare condition primarily occurring in adolescents following frontal sinusitis or head trauma. We present a case of atypical PPT in a 12-year-girl following an insect bite. The patient presented with painful forehead swelling for 4 weeks without any history of head trauma or signs of sinusitis. She had a history of a purulent pimple 2 months before presentation, following an insect bite. The primary diagnosis of PPT was made based on clinical and imaging findings. The patient was treated surgically and medically with intravenous antibiotics and had a satisfactory recovery upon the 6-month follow-up visit. This case highlights the differential diagnosis and thorough evaluation for PPT in a child with acute headache and forehead swelling, even without sinusitis symptoms.

Rhino-orbito-cerebral mucormycosis (ROCM) is the most commonly noted form of mucormycosis, which is the most common secondary fungal infection following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Osteomyelitis is one of the rare sequelae of ROCM, frontal osteomyelitis being the rarest. We present four patients of coronavirus disease 2019 (COVID-19)-associated mucormycosis, who presented with frontal bone osteomyelitis after being treated for ROCM surgically and medically. This is the first case series highlighting this complication in post-COVID-19 mucormycosis patients and needs utmost attention as it can be life-threatening and can cause extreme facial disfiguration. All four patients are alive with salvage of the affected globe and vision being preserved in one patient. If identified early, disfiguration of face and intracranial extension can be avoided.

Pott\'s puffy tumor, a rare condition, is an osteomyelitis involving the frontal bone with accompanying subperiosteal abscess. Patients typically present with swelling of the scalp and forehead, headache, fever, tenderness of the frontal sinus, and nasal discharge. MRI is the modality of choice for diagnosis and assessment. The standard of care is incision and drainage with long-course antibiotics. The prognosis is excellent; however, complications from a hematogenous spread can lead to meningitis or epidural spaces if not treated properly.
