Successful multimodal management of central nervous system solitary fibrous tumor: A case report.

Solitary fibrous tumors (SFTs) are rare neoplasms that can occur in various locations, including the central nervous system (CNS). We present a case report of a 47-year-old male patient with an intracranial SFT who underwent subtotal resection followed by adjuvant radiotherapy. The patient initially presented with chronic left temporal headache and was diagnosed with an intra-axial double-component mass in the left temporoparietal lobe. Histopathological examination confirmed the diagnosis of SFT, and immunohistochemical staining demonstrated positivity for CD34, Bcl-2, and STAT6. Following the incomplete resection, the patient received adjuvant radiotherapy using volumetric modulated arc therapy (VMAT) technique. During radiotherapy, the patient experienced a spontaneous encephalocele rupture but recovered without complications. One year postradiotherapy, the patient showed no recurrence of symptoms or radiological evidence of tumor recurrence. This case highlights the challenges in the diagnosis and management of CNS SFTs and suggests that subtotal resection followed by adjuvant radiotherapy may be an effective treatment approach in achieving favorable outcomes for these rare neoplasms.

Incidentally revealing of CHD in a 52 year-old man: Case report and literature review.

Congenital hernia of the diaphragmatic dome is defined as a congenital embryopathy where all or part of the diaphragmatic dome fails to form during embryonic development. The classification is based on the location of the defect in the diaphragm. In this report, we present a case of Morgani hernia in a 52-year-old man whose sole initial symptom was dyspnea, occurring within the context of a SARS-CoV-2 (COVID-19) infection. Morgagni hernia is a congenital diaphragmatic hernia. It is rare and comprises only about 2% of all diaphragmatic hernias. Most cases of congenital diaphragmatic hernia (CDH) manifest with respiratory distress during infancy. CDH is a rare condition that can occur in adults and can have various symptoms that are often misdiagnosed or not fully investigated. Morgagni's hernia is currently associated with other malformations or anomalies such as Trisomy 21. CT scan of the chest and abdomen remains the best imaging method to confirm the diagnosis. Surgical correction is the only treatment for Morgagni hernia.

Sven Ivar Seldinger (1921-1998): The Founding Father of Interventional Radiology.

Sven Ivar Seldinger, a Swedish radiologist, laid the cornerstone of modern interventional radiology in 1953 with the introduction of his innovative technique for catheter insertion. This technique, known as the Seldinger technique, represents a pivotal advancement in medical procedures, offering a safer, less invasive method for vascular access. The elegance and effectiveness of this technique not only refined angiography and other catheter-based interventions but also heralded the birth of interventional radiology as a major therapeutic specialty. This article delves into Seldinger's life, the genesis of his technique, its profound impact on medical practice, and his enduring legacy that continues to resonate across numerous medical specialties today. By pioneering minimally invasive approaches to treatment, Seldinger's innovation has significantly alleviated patient risk and discomfort, broadening the spectrum of therapeutic options available in modern medicine.

Closed Thoracic Trauma as an Exceptional Cause of Pneumorrhachis: A Case Report.

Pneumorrhachis, a rare clinical entity, refers to the presence of air in the spinal canal. Air can enter the spinal canal through various pathways, including the lungs and mediastinum (the space between the lungs), or directly from external sources due to trauma or infection. In rare cases, pneumorrhachis may result from repeated secondary Valsalva maneuvers, which is a complication of large-area pneumothorax. In this case report, we discuss a 36-year-old male patient who was involved in a high-intensity road accident. The injury assessment revealed significant findings including a large left pneumothorax, a right pneumothorax, multiple rib fractures, and the presence of pneumorrhachis. The entry of air into the spinal canal originated from the pleural space, likely through injuries to the parietal pleura. Rarely reported, closed thoracic trauma is an exceptional cause of pneumorrhachis. This unique mechanism of injury has been described in a limited number of publications addressing traumatic pneumorrhachis. The identification of pneumorrhachis in a traumatized patient should prompt further investigation to explore other potential injuries that may elucidate the formation of this intraspinal gas collection.

Rare images of an intense 18F-FDG PET-scan uptake in an incidentally discovered thyroid lesion: A case report.

Thyroid carcinoma is a type of cancer that starts in the cells of the thyroid gland, which plays a crucial role in regulating the body's metabolism. Thyroid cancer can manifest in various forms. We report the case of an 89 year-old patient presenting an incidental intense Fluorine-18-fluorodeoxyglucose (18F-FDG) PET-computed tomography (PET-CT) uptake within a thyroid lesion and the role of 18F-FDG PET-CT guiding the anatomopathological examination. The prevalence of FDG-avid thyroid incidentaloma ranges between 0.2% and 8.9%. Higher risks of cancer seems to be related to focal or unilateral uptake of 18F-FDG. Lesions with higher standardized uptake values or suspicious CT are more likely to be cancers. The diagnosis is clinically challenging. Nuclear and radiological images can guide practitioners.

Diagnostic Challenges in Adult Intestinal Malrotation: A Case Report and Literature Review.

Adult intestinal malrotation is a rare anatomical anomaly that typically manifests during infancy but can also present in adulthood. Symptoms are mainly digestive, with a long history of intermittent abdominal pain and epigastralgia. It often presents a diagnostic challenge due to the varied and nonspecific nature of clinical symptoms. Radiological evaluations reveal diverse patterns of malrotation, including incomplete rotation, mesenteric base abnormalities, and associated malformations. Computed tomography (CT) scans consistently identify characteristic anatomical distortions, aiding in accurate diagnosis. In this context, we present a unique case in which contrast-enhanced CT of the abdomen, initially conducted to investigate a suspected episode of acute pancreatitis accompanied by epigastralgia, fortuitously revealed the presence of intestinal malrotation. Once the diagnosis has been made, the therapeutic approach is based on monitoring or managing complications such as intestinal obstruction. Early recognition and accurate radiological assessment of intestinal malrotation play an essential role in establishing the diagnosis and guiding appropriate management strategies. Increased awareness among clinicians and radiologists is essential to avoid delays in diagnosis and the potential complications associated with this entity.

Low-grade endometrial stromal sarcoma, a rare uterine tumor: Case report.

This case report describes a 45-year-old woman presenting with abnormal uterine bleeding and a cervical mass. Imaging and biopsy revealed low-grade endometrial stromal sarcoma (LGESS), emphasizing the importance of comprehensive evaluation for uterine masses. The report underscores the role of MRI and pathology in diagnosis, with immunohistochemical analysis helping confirmation. A multidisciplinary approach and vigilant follow-up are crucial for optimal management. The rarity of LGESS and its challenging diagnosis highlight the need for continued research to improve diagnostic and therapeutic strategies. Surgical intervention remains primary, but the optimal management approach is debated. This report indicates the necessity of a comprehensive approach to uterine mass evaluation and ongoing research for enhanced patient care.

Short Stature: Think About the Pituitary Stalk Interruption Syndrome.

Pituitary stalk interruption syndrome (PSIS) is an uncommon congenital defect of the pituitary gland. It is considered one of the rare endocrinal causes of abnormally short stature. Herein, we present a case of a four-year-old girl who consulted for short stature and delayed growth. The patient's history did not include any past medical or surgical pathology. Birth history revealed a full-term delivery with a breech presentation. Clinically, the patient had a small stature, beneath the third percentile. Magnetic resonance imaging findings, through a typical triad, were consistent with PSIS. We describe through this report, what we believe is a rare typical case of PSIS. This case was discovered in a young patient with pituitary dwarfism. We hope that the concise and synthesized structure of this case report will help physicians acquire the necessary reflexes to notice and diagnose the already underdiagnosed PSIS.

Hydatid cyst of the uterus: Very rare location.

The involvement of the genital tract of a hydatid cyst is rare and the occurrence in the uterus is an extreme rarity. The diagnosis of this localization is difficult because the clinical and radiological findings are often misleading and the diagnosis is often worn during surgery and after histopathological examination of the surgical specimen. We report the case of a patient who consulted for primary infertility, with a clinical finding as the only anomaly significantly large uterus, and imaging pointing strongly toward an ovarian multilocular cyst, and in which the discovery of hydatid cyst was accidental intraoperative with double localization uterine and omental. Radical treatment cannot be discussed in this young patient of 32 years and gravid 0. The removal of the cyst wall completely and excision of the mass epiploic seemed reasonable. The patient was placed under Mebendazol and is always under the supervision of a possible recurrence.

Exophytic hepatic hemangioma: a case report.

Hepatic hemangiomas may rarely arise outside the extra-hepatic capsule. It appears as a pedunculated mass. We report the case of a 58-year-old female presenting with abdominal chronic pain. Incidental diagnosis of a pedunculated hepatic hemangioma was suggested by ultrasonography confirmed by typical imaging features on computed tomography. Dynamic contrast- enhanced computed tomography and MR scan are relevant to approach the diagnosis of hemangioma, showing its origin from the liver edge and typical radiological features Surgical removal of the mass was performed to prevent volvulus along the pedicle. Pathological analysis confirmed the diagnosis of pedunculated benign hepatic hemangioma.

Kikuchi-Fujimoto's Disease or Histiocytic Necrotizing Lymphadenitis Following mRNA COVID-19 Vaccination: A Rare Case.

Kikuchi-Fujimoto disease (KFD), also known as necrotizing histiocytic lymphadenopathy, is a rare and benign lymph node disorder that mainly occurs in young women. It is clinically characterized by fever with tender and painful cervical lymphadenopathy mostly; however, all areas of lymph nodes can be involved. This disorder is often mistaken for malignant lymphoma or infection. The precise pathophysiology of KFD remains unknown, but it is theorized that it may be post-viral or associated with an autoimmune disease. The diagnosis is based on the histological analysis of the excised involved lymph node. The treatment is mainly supportive with favorable outcomes within a few weeks or months. In this case, we present a 24-year-old woman without a past medical history, who consulted for painful bilateral cervical lymphadenopathy associated with fever that has been evolving for one month following the coronavirus disease 2019 (COVID-19) vaccination. The initial diagnostic workup was performed and the diagnosis of KFD was confirmed based on the histopathological findings of the excised lymphadenopathy. Therapeutic management was based on oral corticosteroid treatment with clinical and radiological improvement after a few days without recurrence during follow-up. This article aims to report a rare case of KFD in a patient after receiving the messenger ribonucleic acid (mRNA)-based COVID-19 vaccine. Therefore, this case highlights the possible association between COVID-19 vaccination and KFD and this should be considered in the differential diagnosis.

Renal artery pseudoaneurysms post percutaneous nephrolithotomy: A case report.

Percutaneous Nephrolithotomy (PCNL) is a standard, safe and efficient method for removing large renal calculi. This pathology is associated with a risk of life-threatening Iatrogenic Renal Vascular Injuries, such as pseudoaneurysm (1%-3%). We report the case of a 49 old year male patient with Hematuria post PCNL for renal calculi. Computed tomography renal angiography was indicated which showed a pseudoaneurysm in the lower pole of the left kidney confirmed by digital subtraction angiography. Super selective endovascular embolization was successfully performed with conservation of the left-over vascularization of the kidney. No postoperative complications were seen. We aimed to report this case and to review the literature regarding endovascular management of kidney pseudoaneurysms after PCNL.

Metastatic rectal gastrointestinal stromal tumor with intestinal obstruction: A rare case report.

Gastrointestinal stromal tumors (GISTs) arising from the rectum are rare. We report the case of an aggressive rectal gastrointestinal stromal tumor (GIST) in a 60-year-old female that presented for symptoms of constipation and lower gastrointestinal bleeding. Upon rectal examination, a hard mass was found at 6cm from the anal marge. An MRI was indicated that shows a well-demarcated lesion originates from the distal rectum with exophytic growth and central necrosis. The diagnosis of rectal gist was confirmed by colonoscopy with biopsy and immunohistochemical analyses of bioptic material. Liver metastases were seen on computerized tomography (CT). She was referred for palliative chemotherapy. The patient had suffered from intestinal obstruction three weeks after his initial presentation and passed away shortly thereafter. We aimed to report this case as an aggressive and rare GIST localization.

Fortuitous Discovery of Nutcracker Syndrome During Acute Appendicitis: A Case Report.

Nutcracker syndrome (NCS) belongs to a group of rare vascular disorders. It refers to compression of the left renal vein (LRV) generally between the abdominal aorta (AA) and the superior mesenteric artery (SMA). It is one of the most unknown causes of chronic abdominal pain. Herein, we present the case of a young patient who came to the emergency department for acute abdominal pain. Patient's history revealed an uncharacterized chronic epigastric pain evolving for 13 years. The imaging showed acute appendicitis and NCS; the latter finding was the principal explanation for the patient's chronic pain. We hope that the concise and synthetized structure of this case report will help physicians acquire the necessary reflexes to notice and diagnose this already underdiagnosed syndrome.

[Hydrocele of the canal of Nuck detected during infertility evaluation: an atypical case report]. / Une hydrocèle du canal de Nuck découverte au cours d´un bilan d´infertilité: à propos d'un cas atypique.

Hydrocele of the canal of Nuck is a rare woman condition often detected during childhood. We here report a rare case of hydrocele detected in adulthood during infertility evaluation. The patient presented with chronic non painful right inguinal swelling. Imaging test demonstrated typical image of hydrocele of the canal of Nuck. The ultrasound found cyst formation with few thin septa and MRI did not find any communication with the peritoneum. The same imaging tests were performed which showed non-partitioned bicornuate uterus that could fall under the framework of infertility evaluation. The main purpose of this study was to report the typical imaging features of hydrocele of the canal of Nuck, which is a little known diagnosis that should be integrated into differential diagnoses of inguinal swellings in women.

Recurrent costovertebral hydatidosis with epidural extension.

Osseous echinococcosis is a relatively rare entity and that of the rib is even rare. Few cases of costal echinococcosis have been reported in the literature so far. We report a case of a recurrent costovertebral hydatidosis with epidural extension in a 49-year-old man who presented with paraparesis and back pain. MRI of the dorsal spine was performed. The imaging features were suggestive of echinococcosis involving the rib and vertebrae with epidural extension. This diagnosis was confirmed histopathologically after surgical treatment. The evolution was marked by the reappearance of the same symptoms due to recurrence. The prognosis of costovertebral hydatidosis is gloomy despite radical surgical treatment due to the frequency of recurrences. This case highlights the role of MRI for the diagnosis and follow-up of patients after treatment.

Ansa pancreatica: a rare cause of acute recurrent episode in chronic pancreatitis.

Ansa pancreatica is a rare anatomic variation of pancreatic ducts. It is a predisposing factor of recurrent pancreatitis. In this case report, we describe a case of a 24-year-old male suffering from an ansa pancreatica with a non-patent major papilla, diagnosed on magnetic resonance cholangiopancreatography (MRCP).The ansa pancreatica was revealed by an episode of acute pancreatitis attacks in chronic pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed important abrupt dilation in the main pancreatic duct with an ansa loop in the pancreatic duct in the head of the pancreas, and a sphincterotomy of the minor papilla was performed. The procedure was difficult and the placement of a long-term pancreatic stent during the ERCP was impossible, thus a surgical pancreatico-jejunostomy was proposed as a treatment of an ansa pancreatica with a non-patent major papilla.

Clinical and radiological resolution of vertebral sarcoidosis mimicking metastatic disease.

Sarcoidosis is a disease that exhibits extreme heterogeneous clinical manifestations. Bone involvement in sarcoidosis is rare (1%-13%), and involvement of the vertebrae is even rarer. Usually, it is a diagnosis of exclusion with nonspecific characteristics in imaging. A 35-year-old male, who has no significant medical history£. He came to clinical examination for lower back and associated bilateral lower extremity pain. Magnetic resonance imaging (MRI) was performed to exclude disc-related pathology. It demonstrates left paramedian lumbar disc herniation at L4-L5 level. Multiple small enhancing lesions throughout the lumbar vertebrae were discovered as an incidental finding. An 18F-labeled fluorodeoxyglucose was performed to evaluate for metastatic disease that shows hypermetabolic apical right nodule of the lung parenchyma with multiple mediastinal and right iliac external adenopathy. Increased uptake throughout the lumbar vertebral lesions was also seen. A CT-guided biopsy of the right apical lung nodule and one of the vertebral lesions (L3) revealed noncaseating granulomas consistent with sarcoidosis. We introduce steroid treatment with favorable evolution of vertebral lesions. Vertebral sarcoidosis cannot be certainly differentiated from metastatic disease based on imaging only. Accurate diagnosis is only attainable by histopathological verification of the lesions.

Rare location of head and neck adenoid cystic carcinoma.

Adenoid Cystic Carcinoma of larynx is extremely rare location. We herein describe an unusual clinical and radiological presentation of ACCL and review recent literature. We report a case of a 38-year-old woman with history of asthma, presented to our department with acute inspiratory dyspnea that required an emergency tracheotomy. Physical examination revealed a large anterior cervical mass without any lymphadenopathy suspecting thyroid origin. Cervical Computed Scan showed a tumor process between the thyroid lobe, the left edge of the subglottic area and first tracheal rings filling all the lumen, discussing either a laryngo-tracheal or thyroid origin. The patient underwent a panendoscopy under general anesthesia that confirmed a subglottic extension of the tumor and multiples biopsies showed a malignant salivary origin of the mass. After multidisciplinary discussion, the patient underwent total laryngectomy and thyroidectomy with bilateral selective neck dissections (levels II- IV). Anatomopathological examination confirmed the laryngeal location of Adenoid Cystic Carcinoma classified pT4aN0R0. Adjuvant radiation therapy was indicated. In our knowledge, only 10 cases were reported in the literature with this unusual presentation. Moreover, the case we report is in the subglottic floor without invasion of neither vocal cords nor trachea. Total laryngectomy with neck dissection remains the recommended therapeutic procedure for locally advanced ACCL. Adverse features such as close or positive margins, T3-4, intermediate or high grade neural and perineural spread, lymphatic or vascular invasion or lymph node metastases should indicate adjuvant treatment to improve the outcome. The lack of randomized multicentric study, implies the management of ACCL by skilled multidisciplinary team, to suggest adequate personalized treatment.

Creation of the bone bank of the Rabat and Casablanca region in Morocco.

For a long time the use of bone grafting has demonstrated its interest in orthopedic surgery and traumatology. The autografts which are still very frequently used present various problems. On the one hand, it is necessary to find a correct mechanical quality and a sufficient quantity of bone. On the other hand, the graft removal lengthens the operative time and generally painful in postoperative. These disadvantages of autografts have led to the development of bone allografts. Indeed, the low immunogenic power of the bone, the good integration of the graft and the ease of bone preservation techniques make it possible to overcome the various problems posed by bone autografts. The increasing use of bone allografts has resulted in the need for a structure allowing the management of graft stocks. The purpose of this work is to demonstrate the mode of operation of a bone bank, whose conservation activity is limited to the femoral heads treated by cryopreservation and without secondary sterilization process. The bank collaborates with all orthopedic surgeons in the Rabat and Casablanca city at first and then with all orthopedic surgeons in Morocco. It provides allografts in quality and safety.
