Ileal intussusception secondary to lipoma in an adult patient: A rare cause for intestinal obstruction: A case report.

Intussusception is a rare condition in adults, unlike in children, with a variety of etiologies. In most cases, it is secondary to tumors. acute intussusception on lipoma is very exceptional. We report a case of 68-year-old female patient, diagnosed with intestinal intussusception on lipoma.

Cerebellar liponeurocytoma: Rare posterior fossa tumor.

Cerebellar liponeurocytoma is a rare WHO grade II glioneuronal tumor, characterized by a benign course and a more favorable prognosis. In this paper, we report a 52-year-old man, hospitalized in emergency because of clinical signs of increased intracranial pressure, and gait disturbances. The MRI revealed a lateral well shaped solid lesion within the left cerebellar hemisphere, having a low signal intensity compared to the cerebrospinal fluid, and causing a triventicular hydrocephalus and tonsillar herniation. The patient underwent a direct approach of the tumor through a left suboccipital craniectomy. Total removal of the lesion was achieved, and the histological diagnosis was cerebellar liponeurocytoma. The tumor cell proliferation index was < 6 %, therefore, radiotherapy and chemotherapy were not implemented after surgery. After 5 years of close follow-up there were no clinical or radiological signs of recurrence. Our objective in reporting another case of this unusual tumor is to discuss clinical profile, radiologic and histologic features as well as treatment and prognosis of this rare posterior fossa tumor.

Intramyocardial hydatid cyst revealed with ischemic stroke due to left ventricular systolic dysfunction: A case report.

Cardiac echinococcosis, although rare, presents a range of clinical manifestations depending on the cyst's location within the heart. These manifestations can range from asymptomatic conditions to serious complications such as arrhythmias, valvular dysfunction, cardiac tamponade, heart failure, shock, or even death. This case report describes the unusual presentation of a young man with an intramyocardial hydatid cyst, which was incidentally discovered following an ischemic stroke. Diagnostic evaluation included echocardiography, as well as chest and abdominal angiography via computed tomography (angio-CT). Surgical intervention was undertaken, involving cystectomy and the removal of the cyst contents. The patient's postoperative recovery was uneventful and favorable. This report emphasizes important diagnostic and management considerations specific to cardiac hydatid cysts and includes a review of the relevant literature to provide context and depth to our findings.

Using imaging to diagnose renal tumors beyond nephroblastoma.

Wilm's tumor (WT) accounted for the vast majority of renal tumors in children (92%). However, there are many atypical or rare forms of kidney cancer, and it is certainly useful to have a diagnostic orientation in imaging to differentiate between the different diagnoses, guiding that way the therapeutic management. We report the cases of 3 patients who were initially diagnosed with nephroblastoma on the basis of radiological data (via PACS search), underwent pre-operative chemotherapy and then nephrectomy, and whose anatomopathological evidence came back in favor of benign renal tumors. Nephroblastoma is the most common renal tumor in children, but other benign tumors should not be neglected, radiological signs that may point to this entity should be taken into account, so that neoadjuvant chemotherapy with its enfeebling side effects can be avoided.

Crack lung with toxic cerebral vasculitis: Case report.

Crack is the most potent form of cocaine. It directly affects lungs if inhaled and the damage may include barotrauma, acute pulmonary edema, alveolar hemorrhage, bronchiolitis obliterans with organizing pneumonia, or vasculitis. The diagnosis of cocaine-related lung damage is based on clinical symptoms and radiological findings. When young individuals develop respiratory symptoms, investigation into cocaine use is necessary. We report the case of a young man with a history of cocaine use who presented for respiratory and neurological symptoms revealing crack lung and toxic cerebral vasculitis.

Synchronous congenital malignant rhabdoid tumor of the orbit and cerebellar atypical teratoid/rhabdoid tumor: Case report.

Malignant rhabdoid tumor is an uncommon pediatric tumor that often arises from the kidneys but can also develop in other soft tissues including the orbits, where it is known as atypical teratoid rhabdoid tumor. Orbital location is exceptional, with just a few reported cases. Imaging allows for an accurate diagnosis, but histological confirmation is required. The treatment is yet unclear but nearly often surgical, either with or without chemotherapy. In this report, we present a case of a neonate of 1-month-old with an orbital primary malignant rhabdoid tumor with synchronous cerebellar location. The patient was unable to undergo surgery, he had chemotherapy, and unfortunately died 1 week after following palliative treatment. We will illustrate this clinical experience and point out the importance of radiological imaging in the assessment of this uncommon condition.

Incidental finding of undiagnosed aortic coarctation in an elderly patient with a rare association with thymic carcinoma: a case report with review of the literature.

Aortic coarctation is a congenital malformation that is relatively prevalent, occurring in approximately 5 out of every 1000 births. The narrowing typically happens at the aortic isthmus between the left subclavian artery and the arterial ligament. It is frequently associated with a bicuspid aortic valve. Generally, coarctation of the aorta is identified and treated during childhood or early adulthood. If left untreated, this condition can lead to a reduced life expectancy in individuals who have not received treatment. We present a case of a 52-year-old man who complained of chest pain, sputum, and hemoptysis persisting for approximately 2 years. Contrast-enhanced computed tomography (CT) scans revealed the presence of an anterior mediastinal mass, which was later confirmed to be a thymic carcinoma (on histological study). Additionally, an incidental finding of a thoracic aortic coarctation with a well-developed collateral circulation was observed. The discovery of aortic coarctation in adult patients as an incidental finding is rare and particularly uncommon in association with mediastinal or thoracic tumor pathology. Adult and elderly patients with uncorrected coarctation generally have a low survival rate, and the management strategies for such cases are controversial, especially when it is associated to other pathologies. Due to the complexity of therapeutic management and the limited literature available on postsurgical outcomes in these cases, making therapeutic decisions requires a multidisciplinary approach and personalized consideration for each individual case. This approach is necessary to evaluate the risk-benefit ratio and determine the most suitable therapeutic solution.

Neglected trauma-induced testicular torsion: Clinical, sonographic, and surgical correlation in a 13-year-old adolescent.

Post-traumatic testicular torsion is a rare condition, accounting for approximately 4%-8% of all reported cases of testicular torsion in the literature. Prompt clinical suspicion and intervention are crucial; as testicular torsion is considered a medical and surgical emergency that may lead to testicular necrosis. Ultrasound imaging plays an important role in assessing the integrity of the traumatized scrotum and facilitating early detection of associated testicular torsion. In this case report, we present a neglected post-traumatic testicular torsion in a 13-year-old child that led to orchiectomy.

Diagnosis and treatment of mycotic aneurysms secondary to cardiac hydatid cyst: An unusual cause of multiple cerebral strokes in a 23-year-old female.

Mycotic aneurysms (MA) are a rare but severe complication of systemic infections, carrying a high risk of rupture, hemorrhage, sepsis, and potential multiple organ failure. Intracranial arteries are often affected and present a significant mortality risk due to cerebral bleeding and ischemic strokes. In this paper we describe the case of a 23-year-old female patient who presented with a sudden onset of right hemiparesis, followed by loss of consciousness. Cerebral imaging revealed multiple infarcts in both hemispheres and intracranial hemorrhage secondary to ruptured pseudoaneurysms. On transthoracic echocardiogram, she was found to have a left ventricular cardiac cyst with mobile vegetations potentially responsible for mycotic aneurysms and cerebral strokes. The patient underwent endovascular embolization for the mycotic aneurysms and cardiac surgery for the left ventricular cyst with satisfying clinical outcomes. Postsurgical analysis revealed the cyst to be of hydatid (Echinococcus) origin.

Budd-Chiari syndrome secondary to retro-hepatic vena cava web: An unusual cause of epigastric pain.

Epigastric abdominal pain is a common indication for consultation. In the majority of cases, medical history, clinical examination and routine biological exams allow for an easy diagnosis. Sometimes the symptomatology is unusual, in which case it is essential to perform a complete clinical examination and to use various imaging techniques to search for eventual atypical causes. Membranous obstruction of inferior vena cava is a rare cause of such a phenomenon. We describe a Budd-Chiari syndrome caused by membranous obstruction of inferior vena cava in a 66-year-old woman with no medical history as a rare cause of epigastric abdominal pain. We will describe this clinical experience in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Mediastinal and pericardial hydatidosis: A case report with review of the literature.

Hydatidosis is an echinococcosis caused by the development of Echinococcus granulosus larvae in humans. The lung is the second most frequent site after the liver. The primary mediastinal and pericardial localisations are extremely rare. Ultrasound and CT scans play an important role in the diagnosis of this disease.We report the case of an 11-year-old female patient from a rural environment with a history of dogs contact, whose symptomatology consisted of chest pain, dyspnoea, all evolving in a febrile context. The imagery showed the existence of multiple mediastinal and pericardial collections. This patient was rapidly managed with albendazole (ABZ) and scanography revealed an excellent therapeutic response. Primary mediastinal and pericardial hydatidosis is a very uncommon disease. It can be unfortunately revealed at the stage of vital prognosis complications. Ultrasound and computerized tomography (CT) are helpful for localizing and defining the morphologic features of hydatid cysts. It should be kept in mind, especially in patients from endemic areas.

Lumbar puncture as a cause of tension pneumocephalus, pneumorrachis, and sacral meningocele infection leading to death: An extremely rare case report.

Although it was first described over 100 years ago, lumbar puncture is still an important diagnostic tool for a variety of infectious and noninfectious neurologic conditions. With the widespread use of this common and relatively safe performed medical procedure, minor and major complications can occur even when standard infection control measures and good techniques are used, including post lumbar puncture headaches, infection, bleeding, cerebral herniation, radicular pain, and even pneumocephalus in extremely rare cases. We describe a previously unreported complication of lumbar puncture performed for the diagnosis of meningitis in a 33-year-old woman with no medical history causing pneumorrachis, tension pneumocephalus, and sacral meningocele infection leading to death. Lumbar puncture is a simple diagnostic procedure with few complications, but if the technique is incorrectly performed, or if it is accompanied by occult congenital malformations such as sacral anterior meningocele in our case, the consequences can be fatal.

Unusual case of urothelial carcinoma disguised as xanthogranulomatous pyelonephritis and causing reno-colic fistula: Case report and review of literature.

Xanthogranulomatous pyelonephritis is a rare and aggressive form of chronic pyelonephritis, it can occur at all age groups but is more common in women than in men, supposedly relating to the increased incidence of urinary tract infections and chronic nephrolithiasis in woman. Computed tomography (CT) findings are very helpful in making the correct diagnosis, but the definitive diagnosis is still based on histology, as there are many differential diagnoses such as renal cell carcinoma and renal tuberculosis. The complications of this type of pyelonephritis are due to the involvement of adjacent organs. The most frequent ones are Psoas abscess, perinephric abscess, and sepsis. Nephrocutaneous and renocolic fistulas are less common. We report a case of a 61-year-old male, who presented to emergency for left-sided lumbar pain for whom radiological investigations confirmed a renocolic fistula complicating xanthogranulomatous pyelonephritis. The diagnosis of XGP was proven by histopathological examination of the nephrectomy specimen slides, but there was also association with an underlying malignant squamous differentiation consistent with urothelial carcinoma, which was not evident on CT. XGP is a rare variant of chronic pyelonephritis with known imaging features. The treatment of choice is nephrectomy and histopathological examination is required for final diagnosis, as there may be associated renal malignancy.

Early hepatocellular carcinoma developed within dysplastic nodule as nodule-within-nodule appearance: Case report with literature review.

Close follow-up of patients with liver cirrhosis has led to increased detection of hepatocellular carcinoma (HCC) at an early stage, especially with magnetic resonance imaging (MRI) innovations. We report the case of a 70-year-old man, with a recent history of liver cirrhosis due to chronic hepatitis C virus (HCV) complicated by hepatocellular carcinoma (HCC), and for whom trans-arterial chemoembolization (TACE) was planned, as the patient was assigned Child B7 at admission. Angiography performed during the first TACE cycle shows not only the "tumor blush" corresponding to previously detected HCC but also an additional small foci of HCC uptake seen within a large dysplastic nodule giving the appearance of "nodule-within-nodule." Early detection of hepatocellular carcinoma improves prognosis. Hence, it is essential to be aware of all early aspects of HCC, including the nodule-within-nodule appearance on cross-sectional imaging, and also in angiography, as in this case.

Left-sided appendicitis revealing a common mesentery: A Case Report.

Intestinal malrotation is a congenital rotational anomaly that results of abnormal rotation of the gut, said to occur in 1 in 6000 live births. Common mesentery predisposes to volvulus of the midgut and internal hernias due to the left position of the cecum and appendix. The association of this anomaly with acute left appendicitis is rarely reported in the literature. Occurrence of acute appendicitis on common mesentery is a source of diagnosis difficulties, which may lead to a surgical management delay. We report a case of a 10-year-old boy, admitted for a left-sided iliac pain whose radiological investigations confirmed a left acute appendicitis associated with complete common mesentery. The child underwent laparoscopic surgery with simple post-operative follow-up.

A rare case of sphenoid giant cell tumor: Case report & review of imaging features post short-term denosumab treatment.

Background: Giant cell tumors (GCTs) are locally aggressive but rarely malignant bone neoplasms that uncommonly involve the skull. In this report, we describe a tumor of the sphenoid sinus. Case presentation: A 51-year-old female was presented with headache, and bilateral decreased visual acuity, CT scan, and brain MRI revealed an infra-sellar enhancing tumor expanding to the sellar and supra-sellar region which proved to be a GCT. the patient had received 03 months of preoperative denosumab-based treatment and imaging follow-up showed regression in size and morphology modifications of tumor tissue. Conclusion: This is one of few reports to describe the appearance of sphenoid bone GCT, and the first report to highlight the effects of short-term denosumab treatment in GCTb in such a location.

Sigmoid lipoma as an exceptional cause of intussusception and bowel obstruction in adults: A case report and review of literature.

Acute intestinal intussusception in adults is a rare condition, most often secondary to an organic lesion (tumor or inflammation), representing 1%-5% of intestinal obstructions. Pure colic intussusception on lipoma rectal causing bowel obstruction is an exceptional situation. A 60-year-old man presented to the emergency department for acute abdominal pain with marked abdominal distention and red rectal bleeding. A contrast-enhanced abdominal CT scan was performed, which revealed a recto-sigmoid intussusception on lipoma, causing mechanical intestinal obstruction. The patient underwent a partial reduction of the intussusception with partial sigmoid resection and end colostomy. Colonic lipomas of the recto-sigmoid region represent a very rare condition and a subsequent etiology for intussusception and bowel obstruction in adults. However, it should be considered in the differential diagnosis of such situations.

Recurrent stroke in young adults caused by atypical fibromuscular carotid dysplasia.

Background: Carotid Web and focal carotid diaphragm are atypical fibromuscular dysplasia. The bilateral stroke due to this dysplasia is extremely rare. We will report a series of three young patients, admitted for a bilateral ischemic stroke caused by carotid bulb web and internal carotid diaphragm. Also, we will discuss their manifestations and treatment modalities. Case presentations: In our study, we will report a series of three North African patients, two females an one male, at the mean age of 37, admitted for an ischemic stroke caused by bilateral carotid bulb web and bilateral internal carotid diaphragm.All of our patients were young and didn't have a history of drug use. Conclusions: In our series, only end-vascular treatment was performed which was necessary to prevent any recurrence. Antiplatelet therapy was used in all cases to prevent any stroke during the follow-up.

Malignant pelvic paraganglioma: A case report.

Pheochromocytomas arising from outside the adrenal glands are called paragangliomas and constitute a rare disease and can occur in the pelvic retroperitoneum. Symptoms of excess catecholamine production, as well as elevated urine vanillylmandelic acid levels and serum and urine norepinephrine levels, are highly diagnostic for paraganglioma. Imaging can be helpful for the diagnostic of these pelvic tumors, differentiating them from other pelvic masses. We hereby present a case of pelvic malignant paraganglioma.

Hemimelic epiphyseal dysplasia: a case report.

Hemimelic epiphyseal dysplasia HED also known as Trevor's disease is a rare pathology, characterized by a developmental disorder of an internal or external half of one or more epiphyses of a limb, mainly the lower limb, and/or of the short tarsal bones in children and young adolescents, with a male predominance. Its etiology remains unclear. Its clinical symptomatology is variable, ranging from asymptomatic involvement to orthopedic complications such as limb length inequality. As the clinic is non-specific, radiological assessment is the essential diagnostic tool for Trevor's disease, including standard radiography, MRI, CT, and possibly biopsy in some cases. The radio clinical signs make it possible to establish the diagnosis, even if it remains difficult because of the rarity of the disease and the presence of multiple differential diagnoses which are often better known such as osteochondroma and exostosis. After diagnostic confirmation, the therapeutic decision remains debated, ranging from simple observation to surgical excision. The prognosis of HED remains good, given the absence of the risk of malignant transformation. Post-therapeutic complications are dominated by recurrence or the appearance of secondary osteoarthritis. Objective: This clinical case challenges us to keep in mind the hemimelic epiphyseal dysplasia (HED) in front of a mass that originates at the level of the internal or external half of one or more epiphyses in children.
