Breast Tuberculosis

AbstractBreast tuberculosis is a rare form of extrapulmonary tuberculosis which tends to affect females of reproductive age, and is much rarer in males, postmenopausal women, and pre-pubescent girls. It is difficult to diagnose because it can mimic benign conditions such as a fibroadenoma, as well as malignant diseases like a carcinoma. It is also particularly difficult to distinguish breast tuberculosis from granulomatous mastitis, so other possible diagnoses should be ruled out first. The diagnosis of breast tuberculosis has three essential pillars: clinical examination, radiological evaluations, and histopathological sampling. Radiological evaluations are not only critical in diagnosis but are also important in the planning of the treatment and during the follow-up. This paper aims to review the imaging findings and the differential diagnosis of breast tuberculosis.

Acute necrotizing encephalopathy (ANE) is a rare para-infectious encephalopathy that classically occurs in children. However, ANE should be considered in the differential diagnosis of adults with symmetric brain lesions after a prodromal illness given recent reports of coronavirus disease of 2019 (COVID-19) to presumably cause ANE in adults. We report a case of a 29-year-old male presenting with fever, malaise, and rapid deterioration into coma. Brain magnetic resonance imaging revealed multifocal symmetric areas of diffusion restriction and surrounding vasogenic edema involving bilateral thalami, pons and cerebellar hemispheres with a core of susceptibility artifact, and minimal thalamic contrast enhancement, most consistent with ANE. Extensive infectious workup revealed isolated Escherichia coli and Neisseria gonorrhoeae in his urine. Despite the severe encephalopathy on initial presentation, the patient improved with intravenous antibiotics and supportive management with minimal residual deficits at 9 months follow-up. We aim to provide an overview of the radiological features, differential diagnosis, treatment and prognosis of ANE. Becoming familiarized with this rare but devastating disease will improve detection, treatment, and ultimately prognosis, especially in the era of a new pandemic.

Vulvar Mass

Smooth muscle tumors arising in the vulva are rare. Leiomyosarcoma is the most common variant of vulvar sarcoma, and very few cases have been reported during pregnancy. A 36-year-old woman presented with a progressively enlarging vulvar mass during pregnancy, diagnosed as a Bartholin's gland cyst. The lesion was resected at 38 weeks of gestation during cesarean section and diagnosis of myxoid leiomyosarcoma of the vulva was made. Six weeks later the patients were referred to our center and submitted to wide vulvar excision with groin lymph node dissection that revealed the presence of a small residual focus of leiomyosarcoma. At 30 months of follow-up the patient was well without any sign of recurrent disease. Leiomyosarcoma should be included in the differential diagnosis of vulvar masses; progressively enlarging vulvar lesion should be biopsied even during pregnancy. Leiomyosarcoma should be considered in the differential diagnosis of vulvar mass.

Life Threatening

Toxoplasmosis is generally asymptomatic in immunocompetent individuals, but it can be life-threatening in immunocompromised patients. We present a case of a 62-year-old man with clinical features of acute appendicitis. Histology showed a transmural infiltrate of eosinophils. In addition, there were reactive lymphoid follicles with histiocytes in the submucosa and tachyzoites in the muscularis propria. Immunohistochemistry confirmed the diagnosis of toxoplasma appendicitis. Serological evaluation yielded negative results. Retrospective review of the history revealed that the patient was on long-term immunosuppressive therapy with methotrexate. The patient was treated with sulfamethoxazole-trimethoprim and is asymptomatic at 7-month follow-up. Toxoplasma appendicitis must be considered in the differential diagnosis of appendicitis in immunosuppressed patients.

Abstract Central diabetes insipidus (CDI) is a complex disorder in which large volumes of dilute urine are excreted due to arginine-vasopressin deficiency, and it is caused by a variety of disorders affecting the hypothalamic-posterior pituitary network. The differential diagnosis is challenging and requires a detailed medical history, physical examination, biochemical approach, imaging studies and, in some cases, histological confirmation. Magnetic resonance imaging is the gold standard method for evaluating congenital or acquired cerebral and pituitary stalk lesions. Pituitary stalk size at presentation could be normal, but it may change over time, depending on the underlying condition, while other brain areas or organs may become involved during follow up. Early diagnosis and treatment are crucial in order to avoid central nervous system damage, germ cell tumor dissemination, and to minimize complications of multiple pituitary hormone defects. We provide a practical update on the diagnosis and management of patients with CDI and highlight several pitfalls that may complicate the differential diagnosis of conditions presenting with polyuria and polydipsia. The need for a careful and close follow-up of patients with “apparently” idiopathic CDI is particularly emphasized, because the underlying condition may be recognized over time. The clinical scenario that we outline at the beginning of this article represents the basis for the discussion about how the etiological diagnosis of CDI can be overlooked, and demonstrates how a water intake and urine output improvement can be a sign of progressive damage of both hypothalamus and anterior pituitary gland with associated pituitary hormonal deficiencies.

Radiological Studies

Introduction Microhemorrhages (MH) are lesions detected on radiological studies resulting from an underlying small-vessel angiopathy. We assesed the hypothesis that the presence of MH increases the risk of hematoma growth (HG) in patients with acute Intracerebral Hemorrhage (ICH). Methods We evaluated a series of patients in a prospective and multicentre study. We included patients with a spontaneous supratentorial ICH within the first 6 hours after symptom onset, that also had a follow-up CT 24-72 hours later and a MRI performed after a variable time after ICH. HG was defined as an increase >33% in the volume of hematoma on the follow-up CT, in comparison with the admission CT. The volume was calculated using the formula AxBxC/2. On MR scans we assessed the presence, number and distribution of MH. After differential diagnosis with other radiological lesions, MH were evaluated on echo-gradient sequences and defined as hypointense rounded lesions with a diameter <10mm. Statistical analysis: Bivariate tests with the whole sample and with the subgroup of patients with less than 3 hours from symptom onset. Results We studied 46 patients, whose mean age was 68.8±11.2 y and 68% were men. Mean baseline volume was 19.1±27.3 cc. We detected MH in 7/15 patients with HG and in 18/31 patients without HG (46.7% vs 58.1%, p=0.53). In the subgroup of patients with 10 MH, the risk of HG was higher than in patients with 0-10 MH (75% vs 28.6%, p=0.067), and this difference was significant when considering only patients with a <3 hours evolution (100% vs 31%, p=0.044). We did not observe any association between risk of HG and distribution of MH. Age and time to CT were equivalent in the two groups (with and without HG), either in the <6 or <3 hours subgroups. Conclusions In conclusion, in patients with hyperacute ICH, the presence of more than 10 MH increases the risk of HG. This is probably an indirect marker of a more severe underlying angiopathy.

Danlos Syndrome

The Classic Ehlers–Danlos syndrome (cEDS) is an autosomal dominant hereditary disease caused by type V collagen defect. The incidence of pathology is estimated at 1:20,000 of the population. The results of a long-term (15 years) follow-up of a group of patients (n=18) with cEDS, including 5 boys and 13 girls aged from 3 to 18 years, are presented. The diagnosis was made based on the presence of 2 large and 5 small international diagnostic criteria in all patients. The progreduated character of the disease is shown, which is most obvious in the dynamics of the state of the musculoskeletal system. Genetic verification of the diagnosis was performed in 6 patients; 5 probands had mutations in the COL5A1 gene, and one in the COL5A2 gene. Mutations already registered in the database were detected only in 2 children. Previously unknown substitutions were found in 4 patients. The article presents the issues of differential diagnosis of this severe pathology and touches upon the issue of continuity between medical pediatric specialists and doctors of various specialties working with the adult population.
