Recurrent pneumonia in a 2-year-old: A rare case of congenital lobar emphysema.

INTRODUCTION AND SIGNIFICANCE: Emphysema is an uncommon but important condition that often appears in the neonatal period. Diagnosis is based on CT, which identifies the affected lung lobe, which is treated with complete surgical resection. CASE PRESENTATION: We present a case of a child who had been suffering for about a year from recurrent respiratory infections without arriving at a clear and correct diagnosis. He was evaluated by us and diagnosed correctly despite the difficulty of distinguishing it from pneumothorax. The final treatment was surgical removal. CLINICAL DISCUSSION: Emphysema is considered one of the important conditions that should be considered as a differential diagnosis if there is clear hyperinflated in the pulmonary lobe. The evaluation is mainly done through CT to reach the correct diagnosis and treatment. CONCLUSION: Congenital lobar emphysema is a rare condition that primarily affects children. The majority of children with CLE experience symptoms and necessitate surgery.

A rare case of Ewing's sarcoma primary of the cervical spine in a 1-year-old child: A case report and literature review.

INTRODUCTION AND SIGNIFICANCE: Ewing sarcoma is a rare and malignant bone tumor that can primarily affect the cervical spine. Symptoms may not always be present, but muscle weakness is a critical indicator of disease progression and necessitates urgent surgical intervention to relieve pressure on the spinal cord. CASE PRESENTATION: We present a case of a child who experienced sudden muscle weakness in the left upper limb. An MRI of the spine revealed a tumor in the cervical spine compressing the spinal cord. Urgent surgical intervention was performed, successfully removing most of the tumor. This was followed by complementary chemotherapy. CLINICAL DISCUSSION: Tumors located in the cervical spine are challenging to treat due to their location. Urgent surgery may be crucial when muscle weakness is present. This case demonstrates a novel surgical approach through the spinous processes of the vertebrae, avoiding laminectomy and the need for spinal fixation, which can be difficult in children. CONCLUSION: Our case highlights a rare presentation of Ewing sarcoma in the cervical spine, infrequently reported in medical literature. It also demonstrates the success of a novel surgical approach that avoids spinal fixation in children.

Management of pharyngocutaneous fistula following laryngectomy with autologous fat graft: A case report and literature review.

INTRODUCTION AND SIGNIFICANCE: Pharyngocutaneous fistula (PCF) is a serious complication following total laryngectomy, significantly impacting patients' quality of life and treatment costs. Management is complex, with potential for recurrence after surgical intervention. CASE PRESENTATION: We present a case of PCF that developed following laryngectomy. Initial conservative treatment failed to resolve the fistula. A pectoralis major myofascial flap was then attempted, but the fistula recurred. Finally, autologous fat grafting was performed with excellent results. CLINICAL DISCUSSION: Conservative management should be the first-line approach for PCF, as most cases respond favorably. However, if the fistula persists, alternative methods should be explored to achieve optimal outcomes. Our case highlights the importance of not persisting with a failed approach. Autologous fat grafting offers a promising alternative with demonstrably positive outcomes. CONCLUSION: Pharyngocutaneous fistula presents a significant challenge in post-laryngectomy care. Surgical repair can be complex with potential complications. Our case demonstrates the effectiveness of autologous fat grafting as a successful treatment modality.

A rare case of a large mesenteric lymphangioma in a 2-year-old child: Case report and review of the literature.

INTRODUCTION AND SIGNIFICANCE: Lymphangiomas are benign tumors that are typically found in the neck and armpit region but can also occur in other locations. The clinical presentation varies depending on their location and size, and surgical resection is the primary treatment option. CASE PRESENTATION: We present the case of a child who presented with a painless and non-obstructing abdominal mass. The mass was diagnosed and underwent complete surgical resection. Subsequent tissue analysis confirmed that the cyst was a lymphangioma. CLINICAL DISCUSSION: These tumors should be considered in the differential diagnosis of cystic lesions in the abdomen, and the importance of performing complete surgical resection is emphasized. CONCLUSION: The importance of complete surgical resection for mesenteric lymphangioma must be emphasized. Partial resection or aspiration should not be performed due to the risk of complications associated with these procedures and the increased risk of recurrence.

A rare case of an isolated primary hydatid cyst in the uterus in a 7-year-old child: Case report and review of the literature.

INTRODUCTION AND SIGNIFICANCE: Hydatidosis is one of the diseases caused by tapeworms that infect humans during their life cycle and still pose a major problem. A review of the medical literature has reported a few cases of serous cysts in the uterus. In most cases, pelvic cysts are asymptomatic and may sometimes cause compressive symptoms or complications when ruptured. CASE PRESENTATION: We presented a case of a serous cyst of the uterus that was discovered through vague abdominal pain. The definitive diagnosis of the case was made during surgery when the cyst was opened, where it was removed and the cavity was closed completely. CLINICAL DISCUSSION: The diagnosis of a serous cyst is based on a good clinical history, with the help of serological tests, in addition to radiological investigations that help to determine the number of cysts, their location, and their surroundings, in order to choose the appropriate therapeutic intervention according to the size of the cyst and its location, for the best patient care. CONCLUSION: Hydatid cysts of the uterus are rare, but they should be included in the differential diagnosis of pelvic cysts to avoid the accidental rupture of the cyst during surgery and the occurrence of an allergic reaction that can sometimes be fatal.

A case of neck paraganglioma in a 49-year-old male: Case report and review of the literature.

INTRODUCTION AND SIGNIFICANCE: Paragangliomas are rare tumors that most commonly occur in the head and neck. They are typically slow-growing tumors that are often associated with genetic syndromes and mutations in the enzyme succinate dehydrogenase. CASE PRESENTATION: We describe a case of a male patient who presented with ear pain and dysphagia. On physical examination, there was a left neck mass and swalling in the left oropharynx. The mass was excised through a cervical approach and it was found to be a vagal paraganglioma. CLINICAL DISCUSSION: A few cases of head and neck paragangliomas (HNPGLs) have been reported in the medical literature. These tumors often present as asymptomatic masses, but this case, the patient presented with ear pain and dysphagia the location of the mass in the parapharyngeal space presents a surgical challenge. HNPGLs should be considered in the differential diagnosis of any neck mass. CONCLUSION: Paragangliomas are generally considered to have a good prognosis when they are completely excised. They rarely metastasize to adjacent or distant tissues. Cervical approach is a valid option for complete excision of cervical paraganglioma.

A unique case of enteric duplication cyst in the cecum presenting as ileocolic intussusception in a 3-year-old child: Case report and review of the literature.

INTRODUCTION AND SIGNIFICANCE: This is a rare case of enteric duplication cyst presenting as ileocolic intussusception in a child. The literature review found that there have been only a few other reported cases of this condition. In most cases, enteric duplication cysts are asymptomatic and are found incidentally. However, in some cases, they can cause symptoms such as abdominal pain, vomiting, constipation, and diarrhea. Intussusception is a rare complication of enteric duplication cysts. CASE PRESENTATION: We present a case of a enteric duplication cyst in the cecum that was discovered through its association with a ileocolic intussusception that reached the anus. We diagnosed the ileocolic intussusception through an ultrasound, and during surgery, we discovered the presence of the enteric duplication cyst in the cecum. We resected it and performed a ileocolic anastomosis. CLINICAL DISCUSSION: The treatment for enteric duplication cysts that are causing symptoms is surgery. During surgery, the cyst is removed and the intestine is repaired. CONCLUSION: This case report highlights the importance of considering enteric duplication cyst as a possible cause of ileocolic intussusception in children.

A rare case of hepatopulmonary fusion associated with a right congenital diaphragmatic hernia: Case report and review of the literature.

INTRODUCTION AND SIGNIFICANCE: Hepatic-pulmonary fusion is a very rare condition that occurs in the right congenital diaphragmatic hernia and appears to affect both sexes equally. There are no specific diagnostic methods before surgery for this anomaly. Most cases are discovered during surgical repair of the right congenital diaphragmatic hernia. This anomaly is considered to have a poor prognosis because of the associated vascular abnormalities and pulmonary hypoplasia. CASE PRESENTATION: We present the case of a neonate who suffered from respiratory distress since birth. Later, a congenital right diaphragmatic hernia was diagnosed. At surgery, it was found that hepatic-pulmonary fusion was present, accompanied by an anomaly of pulmonary venous outflow. A complete detachment of the connective tissue was performed and a patch was placed to close the defect in the diaphragm. CLINICAL DISCUSSION: The few cases of hepatic pulmonary fusion reported in the medical literature make it difficult to develop a clear plan for diagnosis and surgical management. However, this anomaly should be considered when right-sided congenital diaphragmatic hernia is present, and the case should be well investigated and the surgical decision should not be rushed. CONCLUSION: Hepatic-pulmonary fusion has a poor prognosis and a high mortality rate. No pathological mechanism for this anomaly has been identified, so we could not identify a specific diagnostic mechanism or a specific surgical method to treat this anomaly.

A rare case of thyroid-like follicular carcinoma of the kidney in a 75-year-old male: Case report and review of the literature.

INTRODUCTION AND SIGNIFICANCE: The presence of thyroid-like follicular carcinoma in the kidney is very rare, There have been few documented cases of this tumor's formation, and there are no specific signs for this tumor's presence and it is often discovered incidentally by chance, and the diagnosis depends mainly on histological examination and the negative results of thyroid marker tests. CASE PRESENTATION: We describe the case of an adult male who had prostate adenocarcinoma and later suffered from pain in the flank, so radiographic examination showed a mass in the right kidney, which was removed, and the result of histopathologic examination was thyroid-like follicular carcinoma of the kidney. CLINICAL DISCUSSION: Although this tumor is rare, we need to keep it in mind as a potential diagnosis for renal lesions in our clinical practice. CONCLUSION: The presence of a low-grade malignancy and metastasis in this tumor is a good sign, and this is what motivates us to obtain more reports to better understand the nature of this tumor formation, which is important for human health.

A rare case of Burkitt's lymphoma of the duodenal bulb in a 9 year-old child - A case report and review of the literature.

INTRODUCTION AND IMPORTANCE: The presence of Burkitt's lymphoma in the duodenum is very rare, as this lymphoma is most commonly found at the end of the ileum, as it contains a high proportion of lymphoid tissue, spreads rapidly, and is aggressive. Primary diagnosis by histological examination. It gives a starry sky view with positive for tumor markers. CASE PRESENTATION: We reported a child suffering from recurrent vomiting with weight loss, and a radiological examination revealed the presence of a mass in the duodenum causing obstruction there. Upper gastrointestinal endoscopy was performed, and biopsies were obtained for histologic examination. Burkitt's lymphoma was then diagnosed, palliative surgery was performed, and appropriate chemotherapy was subsequently applied. CLINICAL DISCUSSION: Burkitt's lymphoma is rare in the duodenum. However, it should be considered in the differential diagnosis of duodenal problems to allow early diagnosis and treatment. CONCLUSION: Burkitt's lymphoma is diagnosed by histologic examination and is very aggressive. However, it is highly responsive to chemotherapy in the absence of poor prognostic factors.

A rare case of eosinophilic solid and cystic renal cell carcinoma in a 48-year-old woman: Case report and literature review.

INTRODUCTION AND SIGNIFICANCE: This is (ESC RCC) a rare renal tumor that was thought to occur exclusively in female patients and almost exclusively in TSC patients. The tumor does not have distinctive clinical symptoms or radiological manifestations that are important for distinguishing it from other tumors or renal formations, but it has unique features and distinct histological characteristics that allow us to distinguish it from other tumors. Despite its slow growth, it sometimes metastasizes to other parts of the body. Surgical interventions are treated by examining tissue samples that show the characteristic features of the tumor. CASE PRESENTATION: We present the case of a patient who complained of mild flank pain without other associated symptoms. She was successfully treated in our hospital and followed up for 8 months without any problems. CLINICAL DISCUSSION: This tumor generally has slow growth and good prognosis and is often detected at an early stage. However, when confronted with this tumor, good surgical excision with a full body scan is necessary to rule out the presence of metastases, monitor the patient well, and act decisively despite the good warning of this tumor, as we have not yet achieved complete visualization of this formation. Neoplastic. CONCLUSION: By studying the successive reports of this unique tumor, this manuscript will help document our case and review the literature on this tumor to try to understand this tumor formation in the hope of achieving the best medical care for these patients.

A unique case of complete tubular colonic duplication with normal anus accompanied by vestibular fistula in a 12 years _ old _ girl - A case report.

INTRODUCTION AND IMPORTANCE: Duplication of the digestive system is one of the rare cases, which can vary in shape and size and is cystic in 80 % of cases. Most cases of duplication are often diagnosed before the age of two years. There are many ways to make the diagnosis, with computed tomography being the best, and duplication is often diagnosed during surgery. CASE PRESENTATION: We present the case of a child suffering from complete duplication of colon with normal anus, accompanied by vestibular fistula with double urethra and vagina. The diagnosis was made at our hospital, the necessary surgery was performed, and a future plan for the child's condition was developed. CLINICAL DISCUSSION: a colonic duplication may be associated with malformations of other organs, and sometimes it may be associated with a vestibular or vaginal fistula. Therefore, we must evaluate patients for other anomalies when diagnosing a duplication. The most appropriate diagnostic method is CT, and surgery is recommended in symptomatic or asymptomatic patients. CONCLUSION: When keeping in mind the possibility of a duplication of the digestive system, the surgeon helps to plan the surgery well, in addition to the importance of informing the parents of the possibility of eradication.

Diagnosis and surgical management of a rare case of duodenal duplication cyst in a neonate: Case report and literature review.

INTRODUCTION AND IMPORTANCE: Duodenal duplication cysts are a rare subtype of alimentary tract duplications cysts, consisting of 7 % of all the duplications. The clinical presentation is variable, depending on the size, location and mass effect. Most duodenal duplication cysts abut the second or third portion of the native duodenum. The standard treatment of choice for symptomatic enteric duplication cysts is complete surgical removal. In our case, by examining the abdomen, ectopic pancreatic tissue was found on the wall of the transverse colon, along with Meckel's diverticulum, 50 cm from the ileocecal junction. CASE PRESENTATION: We present a newborn case presented to the hospital with a history of abdominal mass with jaundice. Abdominal ultrasonography and CT scan show the presence of a cystic mass without specifying its exact source. By opening the abdomen, it was found at the expense of the duodenum, and it was excised and On histopathological analysis, a duodenal duplication cyst was diagnosed. The literature was reviewed and the approach to duodenal duplication cyst in neonates is discussed. CLINICAL DISCUSSION: Duodenal duplication cysts are rare, even so should be taken into consideration when a mass is found. A thorough imaging investigation is crucial in establishing the diagnosis along with histopathology. CONCLUSION: When diagnosing a Duodenal duplication cysts, the cyst must be completely removed because potential risk of malignant transformation.

Data Augmentation in Classification and Segmentation: A Survey and New Strategies.

In the past decade, deep neural networks, particularly convolutional neural networks, have revolutionised computer vision. However, all deep learning models may require a large amount of data so as to achieve satisfying results. Unfortunately, the availability of sufficient amounts of data for real-world problems is not always possible, and it is well recognised that a paucity of data easily results in overfitting. This issue may be addressed through several approaches, one of which is data augmentation. In this paper, we survey the existing data augmentation techniques in computer vision tasks, including segmentation and classification, and suggest new strategies. In particular, we introduce a way of implementing data augmentation by using local information in images. We propose a parameter-free and easy to implement strategy, the random local rotation strategy, which involves randomly selecting the location and size of circular regions in the image and rotating them with random angles. It can be used as an alternative to the traditional rotation strategy, which generally suffers from irregular image boundaries. It can also complement other techniques in data augmentation. Extensive experimental results and comparisons demonstrated that the new strategy consistently outperformed its traditional counterparts in, for example, image classification.

Case report: A unique case of benign teratoma in the posterior mediastinum associated with anterior meningomyelocele in a one-year-old child.

INTRODUCTION AND IMPORTANCE: Benign cystic teratoma considered an extragonadal germ cell tumor that can present at any age and mostly located in the anterior mediastinum, only 3 %-8 % are in the posterior mediastinum. Meningomyelocele is an abnormal herniation of the meninges that located in most cases posteriorly in lumbosacral spine. Cervicothoracic meningomyelocele are rare entities resemble only 1 %-5 % of all neural tube defects. The presence of both anterior meningomyelocele (MMC) an benign teratoma is very rare and this association in the thoracic column has never been mentioned before in the medical literature. CASE PRESENTATION: We present the case of a one-year-old child, who was admitted to our hospital with a complaint recurrent vomiting episode, and respiratory distress, with no improvement in symptoms after conservative treatment. Computed tomography showed an anterior heterogeneous meningomyelocele that extend posteriorly to the upper lobe of right lung tissue. MRI confirmed the presence of the meningomyelocele in addition to a heterogenous cystic structure within. Thoracotomy was indicated and the meningomyelocele was carefully resected and sent to histopathology analysis which showed the presence of a benign teratoma accompanying the meningomyelocele. CLINICAL DISCUSSION: Meningomyeloceles and teratoma are rarely associated, especially in the thoracic spine. Mediastinal tumors should be taken into consideration when a mass is found. A thorough imaging investigations is crucial in establishing the diagnosis along with histopathology after complete resection. CONCLUSION: In the presence of posterior mediastinal meningomyelocele with heterogeneity, a histopathological examination of the specimen should be performed to exclude the mediastinal tumors.

Case report: A rare case of congenital non-metastatic low-grade fibrosarcoma of the pleura in a 6-month-old infant manifested as pneumonia.

INTRODUCTION AND IMPORTANCE: Congenital Infantile fibrosarcoma is a rare tumor in children and accounts for only 10 % of various malignant tumors in this age group. Manifestations vary according to the site of occurrence. Symptoms of the tumor located in unusual places can be misleading and obscure the actual diagnosis, which in turn may waste precious effort and time until the correct diagnosis is established. Infant malignancies should be considered to reduce the morbidity and mortality associated with this pathology. CASE PRESENTATION: We present the case of a 6-month-old infant, who was admitted to our hospital with a one-month history of high fever and dry cough, with no improvement in symptoms after treatment with antibiotics. Computed tomography showed a heterogeneous mass in the pleural cavity compressing the lung tissue, in addition to bilateral mild pleural effusion. Thoracotomy was indicated and the tumor was completely resected. CLINICAL DISCUSSION: Histopathological and Immunohistochemical approach is crucial because this type of tumor can overlap with many soft tissue sarcomas. After searching in medical literature, no published evidence of a similar case was found, and thus we managed the patient empirically, depending on the usual approach for congenital fibrosarcoma. Complete surgical resection is the golden standard of treatment, followed by chemotherapy depending on pathological findings. CONCLUSION: Clinical awareness is important in any unresponsive pneumonia and malignancies should be taken into consideration.
