A rare case of hereditary spastic paraplegia: Case report.

Hereditary spastic paraplegias represent a rare set of monogenic disorders encompassing 79 distinct genetic variations. The principal culprit behind recessive hereditary spastic paraplegia is frequently attributed to mutations in the spastic paraplegia gene, particularly type 11, closely followed by type 15. This category is typically characterized by nonspecific clinical features, including cognitive decline, which may precede the development of progressive lower limb weakness and spasticity.

Unusual MRI abnormality in patients with nonketotic hyperglycaemia-associated seizures.

Nonketotic hyperglycaemia (NKH) is a metabolic disorder typically observed in individuals with inadequately managed or undiagnosed diabetes mellitus (DM). Seizures are a common clinical presentation in NKH, and they tend to respond better to glucose correction than anticonvulsant therapy. MRI scans may reveal both subcortical T2/fluid-attenuated inversion recovery (FLAIR) imaging hypointensity and cortical changes, including cortical grey matter T2/FLAIR imaging hyperintensity and cortical or leptomeningeal enhancement, although cortical abnormalities are less frequently observed.

An unusual complication of acute appendicitis: isolated superior mesenteric venous pylephlebitis.

Septic thrombophlebitis of the portal vein or one of its tributaries is referred to as pylephlebitis. It is unusual to have superior mesenteric venous thrombophlebitis. It frequently arises as a result of an infection in the portal venous system's drainage area, such as appendicitis or diverticulitis.

Unusual case of small bowel intussusception in adult revealing a Peutz-Jeghers syndrome.

Peutz-Jeghers syndrome is a rare genetic disorder characterized by hyperpigmented mucocutaneous macules, hamartomatous polyps of the small intestine, and family history. These hamartomatous polyps can cause intermittent abdominal pain, chronic anemia, or even intussusception. Imaging has an important role in the diagnosis of this syndrome but also in the identification of complications and periodic surveillance.

Cystic mass of the right iliac fossa: don't forget about lymphatic malformation.

Lymphatic malformation or cystic lymphangioma is a benign tumour of the lymphatic vessels. It is more commonly reported among children and has polymorphic clinical presentations. The diagnosis is based on imaging but requires histological confirmation.

An unusual cause of obstructive jaundice: Lemmel's syndrome.

Lemmel's syndrome is a rare and misdiagnosed cause of obstructive jaundice. The cause of the obstacle is a duodenal diverticulum located at the periampullary generating a compression effect on the common bile duct with secondary dilation of the extra- and intra-hepatic bile ducts. Late diagnosis of this entity is common and may lead to unnecessary further investigations and therapeutic delay.

Hydatid pulmonary embolism: An exceptional complication of hydatid disease.

We present an extremely rare case of a young man with hydatid pulmonary embolism caused by a direct invasion of the pulmonary artery by a hydatid cyst. Even if it is a benign parasitic disease, it can lead to serious complications such as arterial, systemic, or multivisceral dissemination or being responsible for an anaphylactic shock. Because of the clinical polymorphism, the diagnosis can be delayed.

[Lysis at the dorsal vertebral bodies showing chronic contained rupture of an aneurysm: about a case].

Chronic contained ruptures of aneurysms are extremely rare. They can result from aneurysm rupture. Indeed, the most dreaded complication of aneurysm is its rupture, which is often fatal.

[Plexiform cervical neurofibroma: about a case].

Plexiform neurofibroma is a rare benign tumor of the peripheral nerves involving the conjunctiva cells of the perineurium. It is pathognomonic of neurofibromatosis type1 (NF1 or Von Recklinghausen disease). MRI is a great help in the diagnosis of this pathology.

[Rare digestive tumors: gastrointestinal stromal tumors (GISTs): about a case of small bowel location and literature review].

Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells.

[Mirizzi's syndrome: a rare cause of biliary tract obstruction: about a case and review of the literature].

Mirizzi's syndrome is a rare complication of chronic vesicular lithiasis with prevalence ranging from 0.7% to 1.4% among patients who have undergone cholecystectomy.

[Giant congenital intrapericardial left atrial appendage aneurysm: about a case and review of the literature].

Left atrial appendage aneurysm is a very rare heart anomaly. It may be congenital or acquired, secondary to inflammatory or degenerative processes. Most cases are asymptomatic.
