Progressive ataxia and palatal tremor (PAPT) with hypertrophic olivary degeneration (HOD): A case report.

Palatal tremor has been subdivided into essential (EPT) and symptomatic palatal tremor (SPT). Progressive ataxia and palatal tremor syndrome (PAPT) is a subgroup of symptomatic palatal tremor (SPT). It can be divided into familial and sporadic forms. Sporadic PAPT is characterized by progressive cerebellar degeneration. The cause of sporadic PAPT remains uncertain. MRI examination found an enlarged appearance of the olivary nuclei with increased signal intensity on T2 and FLAIR images. Here we report a case of a mid-adult-onset man which presents a worsening cerebellar progressive ataxia with palatal tremor, in whom imaging reveals abnormalities of the olivary nuclei with tardive cerebellar atrophy which has been diagnosed as a sporadic PAPT.

Intrahepatic abscess secondary to retained stercolith, following laparoscopic appendectomy.

Abscesses of the peritoneal cavity and in particular hepatic abscess due to stercolith retention are a rare complication of appendectomy. Their prevalence is likely to increase as laparoscopic appendectomies become more common. This potentially serious complication can be prevented by following certain technical recommendations. Percutaneous drainage is bound to failure since it leaves the coprolite that causes the recurrence of the abscess, thus when it happens it requires surgical drainage. We report a case of a 40-year-old man, who underwent laparoscopic appendectomy 8 months prior, and presented to the emergency department for acute pain of the right hypochondrium. The radiologic investigations revealed 2 abscesses of the liver and the right iliac fossa containing a central spontaneously hyperdense stercolith. The patient was treated with open surgery removing the stercoliths and draining of the abscesses, with favorable postoperative outcome.

Intra-abdominal abscess from dropped gallstone: A case report.

Dropped gallstones are a common complication during a laparoscopic cholecystectomy. The formation of an abdominal abscess related to the dropped gallstones is rare because the majority of these calculi do not cause complications. Ultrasound is a usually used first-line imaging modality to detect gallstones in the abscess. CT scan may be used to confirm the diagnosis of abscess and for topographic analysis. We report the case of a lady presented to the emergency department 2 months after laparoscopic cholecystectomy; for acute cholecystitis; with acute abdomen and fever. Laboratory values revealed an elevated white blood cell count (WBC) and C-reactive protein concentration (CRP). The diagnosis of intra-abdominal abscess was evoked by ultrasound and contrast-enhanced CT, and confirmed by laparoscopy. The purpose of this paper is to illustrate the importance of searching and recognizing dropped gallstone within collection, particularly in the context of previous laparoscopic cholecystectomy.

Lemmel syndrome: an unusual cause of biliary obstruction secondary to a duodenal juxta-ampullary diverticulum: a report of two cases.

Lemmel's syndrome is a rare cause of obstructive jaundice caused by a periampullary duodenal diverticulum compressing the intrapancreatic common bile duct with resultant bile duct dilatation, patients with Lemmel's syndrome usually present with abdominal pain or jaundice. Cross-sectional imaging is beneficial in making the diagnosis noninvasively, thus eliminating other pathologies of the peri-ampullary region. Although rare, we recognize the importance of considering this syndrome to be able to make a diagnosis and offer timely treatment. We present 2 cases of Lemmel's syndrome whose diagnosis is retained based on a CT scan and magnetic resonance cholangiopancreatography.

Unusual finding of bronchopulmonary carcinoma through a pterygoid muscle metastasis. About a case.

Bronchopulmonary cancer muscle metastases are uncommon, especially when they are visible. They can impact any muscle in the body, but the psoas, diaphragmatic, and paravertebral muscles have a clear advantage. We present a case of lateral pterygoid muscle metastasis of squamous cell carcinoma of the lung in a 70-year-old habitual smoker (40 packs per year) presents headaches more marked on the right and progressively worsening. A complementary brain MRI revealed a well-limited oval formation with irregular contours in hypo signal T1 hyper signal T2 heterogeneous, with area of central necrosis of the right pterygoid muscle, which was revealed to be a secondary location of bronchopulmonary malignancy after further examination (CT scan of the cervico-thoraco-abdomino-pelvic region, TEP scan, and biopsy). Moreover, muscle metastases are rarely revealing of primary cancer.

Achilles swelling and ataxia in an adolescent: A case report of cerebrotendinous xanthomatosis.

Cerebrotendinous xanthomatosis (CTX) is a rare hereditary disease characterized by a bile acid metabolic problem that causes cholesterol metabolites to accumulate in various organs. There are 2 types of CTX: traditional and spinal. The imaging characteristics are usual and allow for diagnosis confirmation. The brain's magnetic resonance imaging (MRI) reveals bilateral dentate nucleus lesions as well as modest white matter abnormalities. Tendon xanthomas (typically in the Achilles tendons on both sides) are a common finding. Cerebrotendinous xanthomatosis is a multidisciplinary diagnosis that must be made early to avoid neurologic injury and worsening. We show a CTX instance that has typical imaging and biology features.

[Mayer-Rokitansky-Küster-Hauser syndrome: a cause of primary amenorrhea: about a case]. / Le syndrome de Mayer-Rokitansky-Küster-Hauser comme cause d'aménorrhée primaire: à propos d'un cas.

Mayer-Rokitansky -Küster -Hauser syndrome (MRKH) is a rare cause of primary amenorrhea. It is defined as congenital aplasia of the uterus and of the upper two thirds of the vagina in women with normal development of secondary sexual characteristics. Diagnosis is essentially based on magnetic resonance imaging (MRI). We here report the case of a 17-year-old girl presenting with primary amenorrhea with well developed secondary sexual characteristics. Laboratory tests revealed normal ovarian function as well as gonadotropic axis. Pelvic ultrasonography and magnetic resonance imaging revealed complete uterine agenesis of the uterus, the upper two-thirds of the vagina and left kidney, allowing to confirm the diagnosis of Mayer-Rokitansky-Küster-Hauser syndrome type II. This study highlights the importance of suspecting MRKH in young patients with well-developed sexual characteristics and any type of primary amenorrhea as well as of performing MRI in order to detect any specific sign of this disorder.

Cystic meningioma: A case report with a literature review.

Cystic meningiomas are very rare tumors of the central nervous system. We report the case of a 62-year-old female how presented headaches resistant to usual analgesics with behavior disorders. Cerebral CT scan showed a right frontal extra-axial tumor with firm and cystic component, brain MRI evoked the diagnosis, surgery removed the entire tumor and histological examination confirmed it. A cystic meningioma should not be omitted from the differential diagnosis of brain tumors with a cystic component and which clinical, radiological, histological and therapeutic features are discussed.

[Plexiform cervical neurofibroma: about a case]. / Neurofibfrome plexiforme cervical: à propos d'un cas.

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. Anatomopathological confirmation is sometimes necessary, in particular in patients with no signs of NF1. We here report the case of a little girl with cervical plexiform neurofibroma revealing neurofibromatosis type 1.
