Huge primary retroperitoneal mature cystic teratoma mimicking adrenal incidentaloma: A case report and literature review.

INTRODUCTION: Teratomas originating from extra-gonadal account for 15 % of all teratomas, while retroperitoneal site being the least site for teratoma 1-11 %, extremely rare adrenal teratoma is less than 4 % of the retroperitoneal teratomas. Usually, patients are asymptomatic and the tumours are detected incidentally during imaging. PRESENTATION OF CASE: A case of a 29 years old female, presented with intractable pain for four weeks. Computed tomography scan study of the abdomen showed an avascular septate cystic lesion measuring 11.6 × 11.4 14.5 cm (cranial-caudal x transverse x anterior-posterior) with central fat density and large punctate calcification in the right suprarenal region displacing the inferior vena-cava laterally, abutting the gall bladder, pancreas and duodenum. Impressions of right adrenal teratoma and less likely adrenal myelipoma were suggested. She remarkably improved one day post operation. During clinic visit a month later, she was completely recovered and resumed her daily activities. DISCUSSION: In adults primary retroperitoneal mature cystic teratoma are uncommon, mostly are secondary tumours and very rare will occur in adrenal gland. Adrenal incidentaloma have been seldom reported mimicking primary mature cystic teratoma. Biochemical and Imaging studies are of great importance in diagnosing and showing relationship of the tumour and other organs. This work has been reported in line with the SCARE criteria (Agha et al., 2018 [1]). CONCLUSION: Primary retroperitoneal tumours are rare and surgery is the main stay of treatment whether it be open or laparoscopic, the latter being best for small lesion for it offers early recovery and complete excision gives excellent prognosis of 100 %.

Idiopathic fibrosing mediastinitis with esophageal varices: A case report.

Fibrosing mediastinitis (FM) is a rare cause of lung fibrosis with multiple etiologies ranging from infectious to autoimmune to idiopathic. Common causes of FM include histoplasmosis and a relatively new cause of IgG4-related disease. We present a 55-year-old male with symptoms of esophageal varices, intractable hiccups, and progressive difficulty in breathing. A chest X-ray showed right lung fibrosis with pleural effusion and loss of lung volume, which was originally thought to be the sequelae of SARS-CoV-2 or metastasis, but computed tomography of the chest revealed FM. His variceal bleeding was controlled, and he was discharged home. However, treatment for FM was not pursued because the cause was not identified. Using corticosteroids may not cease the progression of the disease, and surgical options are available when symptoms persist. Idiopathic FM requires laboratory and radiological findings to exclude relevant differential diagnoses.

Thymoma: a fatal case report of recurring pneumonia from Tanzania.

Thymomas present either concurrently with myasthenia gravis, with local pressure symptoms, or asymptomatically as a mediastinal mass. Due to its variable presentation, the incidence is low, as not all cases would be identified. Thymomas can present with a rare entity of combined T-cell and B-cell immunodeficiency in adults. Thymectomy is the most important prognostic factor, including preventing autoimmune manifestations of thymoma, but immunodeficiency may persist after thymectomy. Case presentation: The authors report a case of thymoma with evidence of immunodeficiency, manifesting as recurrent pneumonia and respiratory distress in an HIV-seronegative 62-year-old man with a suspected diagnosis 3 years before admission. During his bouts of pneumonia, blood cultures revealed methicillin-resistant Staphylococcus aureus, which was initially treated with vancomycin and then with clindamycin. Although hypogammaglobulinemia was not established in our low-resource setting, there was a reduced CD4-cell count with an abnormal CD4/CD8 ratio. The patient responded well to the first course of antibiotics. However, the second attempt was unsuccessful, which led to his demise. Conclusion: Clinicians should be aware that thymoma can cause immunodeficiency. Clinical suspicion should be raised in patients who present with recurrent infections, particularly in thymoma cases with adult-onset immunodeficiency.

Long COVID? Fatal case report of ischemic stroke and pulmonary embolism post COVID-19 infection.

Coronavirus disease 19 (COVID-19) may lead to post-COVID syndrome a few weeks to months after the infection with various symptoms. Post-COVID thromboembolic syndrome may be a result of coagulopathy that occurs in both the arterial and venous circulation. Apart from direct cellular infection, post-COVID syndrome may occur due to immune system dysregulation, endothelial injury, and hypercoagulability, leading to thrombosis. We present a 32-year-old man who was diagnosed with mild symptoms of COVID-19 infection 4 months before an acute ischemic stroke and an asymptomatic pulmonary embolism. A COVID-19 antigen test was negative. An analysis of prothrombotic factors was negative. He could not receive any therapeutic intervention before his demise. The extent of COVID-19 infection after the onset of symptoms is a mystery and poses a fatal concern due to the increasing number of complications. The long-term complications after COVID-19 infection are still not understood. Clinicians need to be aware of any signs and symptoms that may arise months after COVID-19 infection and its possible causal relationship.

Heterotaxy Syndrome with Polysplenia, Fused Adrenal Glands, and Diabetes Mellitus.

Heterotaxy syndrome is a rare congenital heart disease with a disarrangement of the heart and abdominal organs. We present a young African female with features of heart failure, diffuse irregular cardiac murmurs, and palpable, tender epigastric mass. A chest and abdominal computed tomography (CT) identified heterotaxy syndrome with left isomerism and fused adrenal glands. This case highlights the feature of fused adrenal glands in a patient with polysplenia.

Idiopathic Arachnoiditis of the Cauda Equina: A Case Report from Tanzania.

Arachnoiditis is a rare clinical entity that usually presents with severe debilitating radiating pain that can pose a challenge in diagnosis especially in areas without appropriate imaging modalities. We present a 26-year-old male with progressive lower back pain with radiation to the lower extremities, aggravated by movement and touch. We diagnosed idiopathic arachnoiditis based on cerebrospinal fluid analysis and magnetic resonance imaging. He was managed with a 5-day course of methylprednisolone and analgesics with a good outcome. Severe back pain without a specific cause in a young patient should be investigated with proper imaging modalities and lumbar puncture if warranted to evaluate the cause.

Sarcomatoid hepatocellular carcinoma in a young African female.

Sarcomatoid hepatocellular carcinoma is a rare primary malignant liver cancer. The pathogenesis is unclear; however, the risk factors may be similar to that of conventional hepatocellular carcinoma. We present an 18-year-old female who was admitted due to generalized tonic-clonic convulsions. On examination, we palpated a large non-tender mass in the right upper quadrant. An abdominal computed tomography identified it as hepatocellular carcinoma, and spindle-shaped cells were seen on histopathology. She was counseled on her prognosis but opted for local herbal medications rather than chemotherapy, but unfortunately passed away. We present a rare subtype of hepatocellular carcinoma in a young female which is commonly seen in males above the age of 50 years, and despite its grade and stage, overall survival is poor.

Hepatocellular carcinoma in a non-cirrhotic liver with a tumor thrombus.

Young adults with HCC tend to have a poor prognosis because of advanced disease despite preserved liver function. Screening and early diagnosis for HCC are needed for young adults to demonstrate an improved prognosis, especially in HBsAg positive patients.

Loss of consciousness during air travel: A case of lung bullae.

A giant lung bulla occupies at least a third of the lung space. We present a middle-aged man who lost consciousness during an air flight for 30 minutes, without any respiratory symptoms. An incidental finding on chest x-ray revealed a giant bulla and a chest computed tomography imaging confirmed the diagnosis and ruled out a tension pneumothorax. A giant lung bulla is an uncommon cause of loss of consciousness and may be suspected if it occurs during air travel.

Fatal cerebral venous sinus thrombosis as a manifestation of uncontrolled systemic lupus erythematosus in a young African female.

In a young patient with systemic lupus erythematosus presenting with status epilepticus and neurological deficits, early brain imaging, risk factor identification and prompt treatment of underlying lupus flare-up and cerebral venous sinus thrombosis could significantly improve the management and prognosis.

Advanced lung cancer presenting with malignant pericardial effusion.

Irregular pericardial wall thickening, mediastinal lymph nodes, and pericardial fluid analysis are helpful to identify metastasis to the pericardium though it is a marker of advanced disease and poor prognosis.

Status epilepticus and diabetes ketoacidosis: uncommon clinical presentations of acromegaly.

SUMMARY: Acromegaly is a rare disease caused by hypersecretion of the growth hormone (GH). Most cases are caused by either pituitary microadenoma or macroadenoma. The GH producing tumors present with clinical manifestations of acromegaly due to excessive GH secretion or symptoms resulting from mass effects of the enlarging tumor. The physical changes are usually slow and, therefore, recognition of the disease is delayed. These adenomas are never malignant but can have significant morbidity and mortality. A subgroup of patients with acromegaly present with severe hyperglycemia resulting in diabetic ketoacidosis (DKA) which requires insulin. Rarely are pituitary tumors responsible for generalized convulsions except when they are too large. We hereby present two cases, the first is that of a 26-year-old female who presented with new onset status epilepticus, DKA with a 1-year history of diabetes mellitus (DM). On examination, she had clinical features of acromegaly. The second case is that of a 34-year-old female who presented with new onset status epilepticus, hyperglycemia with a history of recently diagnosed DM, and features of gigantism. In both cases, their diagnosis was confirmed by elevated serum GH and later by elevated insulin-like growth factor type 1 levels, and CT of the head demonstrating large pituitary macroadenoma. The importance of clinical history and examination, as well as investigations is vital in the recognition of acromegaly. The prognosis of acromegalic patients depends on early clinical recognition and tumor size reduction by either medical or surgical therapy. LEARNING POINTS: Conditions such as status epilepticus and DKA may be clinical presentations in patients presenting with acromegaly. Seizures are rare in people with pituitary adenoma and typically occur when the tumor invades the suprasellar area due to mass effect on the brain. This article shows how best we were able to manage the acromegaly complications in a low resource setting. Hyperprolactinemia in acromegaly may be due to disruption of the normal dopaminergic inhibition of prolactin secretion due to mass effect of the macroadenoma, and around 25% of GH-secreting adenomas co-secrete prolactin.

A case of computed tomography diagnosis of truncus arteriosus type IV.

Persistent truncus arteriosus is a rare congenital heart disease with four variants, and the last being the rarest. The prognosis without surgical intervention is poor. In such cases, an echocardiography is not sufficient hence computed tomography (CT) imaging is required. We report a 26-year-old female with difficulty in breathing since childhood with cyanosis. Her echocardiography showed a ventricular septal defect (VSD) and the CT showed a single arterial trunk overriding the interventricular septum with a VSD, and the descending aorta giving rise to the pulmonary arteries suggestive of pseudo truncus, known as truncus arteriosus type IV.

Lower Gastrointestinal Involvement in Multiple Myeloma: A Case Report.

Multiple myeloma (MM) commonly presents with anemia and bone pain. Besides bone marrow involvement, MM has a tendency to involve other organs with gastrointestinal (GI) tract, especially lower GI tract involvement being uncommon. Our case shows an elderly male with anemia due to suspected GI malignancy. Investigations revealed anemia, thrombocytopenia, positive stool occult blood and inconclusive diagnostic endoscopic findings. An elevated serum total protein, serum calcium and serum creatinine gave rise to the suspicion of MM which was later supported by the fulfilment of the CRAB criteria, expressed as hypercalcemia, renal failure, anemia and lytic lesions on skull X-ray. The relationship between multiple myeloma and GI bleeding is rare and indicates extramedullary disease which is a sign of poor prognosis. Early detection may alter the prognostic course of MM.

Clinical Characteristics and Factors Associated with Heart Failure Readmission at a Tertiary Hospital in North-Eastern Tanzania.

INTRODUCTION: Heart failure (HF) is characterized by frequent episodes of decompensation, leading to a high hospitalization burden. More than 50% of index hospitalizations for HF patients return within 6 months of discharge. Once the patient is readmitted, the risk of further disease progression and the mortality rate are increased. A lot of patients are readmitted due to factors such as poor medication adherence, infections, or worsening comorbidities. The aim of our study was to identify the inpatient burden of HF readmission and to identify the factors associated with early readmission. METHODS: A hospital-based cross-sectional analytical study was conducted from November 2018 to April 2019 within the medical wards at Kilimanjaro Christian Medical Centre (KCMC), which is a teaching and referral hospital in north-eastern Tanzania. The study population included all patients with HF admitted within the medical ward. Data were collected using questionnaires and blood and radiological investigations, and analysis was done using Statistical Package for Social Science (SPSS) version 25. Chi-square test was used to compare proportions of categorical variables. Logistic regression was used to determine the likelihood for readmission, and p-value of <0.05 was considered to be statistically significant. RESULTS: A total of 353 patients were identified with HF, of whom 136 (38.5%) had a previous admission. Of the 136 patients analysed, the mean age was 62.8 years (SD 17.1), and 86 (63.2%) were females. Within 30 days after discharge, 34 (25.0%) of the patients were readmissions. Factors for early readmission were unemployment (OR = 2.38, 95% CI = 1.02-5.54, p = 0.043), poor medication adherence (OR = 3.87, 95% CI = 1.67-8.97, p = 0.002), absence of angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) (OR = 2.40, 95% CI = 1.09-5.31, p = 0.030), and pleural effusion (OR 3.25, 95% CI = 1.44-7.32, p = 0.004). CONCLUSION: Heart failure is a burden due to a large number of admissions and readmissions. Factors such as poor medication adherence and absence of adequate HF therapy, especially the absence of regimes containing ACEI or ARB, need to be targeted to reduce the number of readmissions. This will help reduce the risk of further decompensations, disease progression, and mortality rate.

Ellis-van Creveld syndrome in a patient from Tanzania.

We report an African infant with Ellis-van Creveld (EVC) syndrome. EVC syndrome is a chondral and ectodermal dysplasia with autosomal recessive transmission. The baby presented with polydactyly, short limbs and atrioventricular septal defect, but was withdrawn from clinical follow up for the first year of life. Initial hematological abnormalities could not be explained and normalized later. EVC syndrome was confirmed by genetic analysis that showed two pathogenic mutations in the EVC2 gene, c.653_654del, p.Val218Glyfs*12 in exon 5, and c.2710C>T, p.Gln904* in exon 16. The variant c.653_654del; p.Val218Glyfs*12 in exon 5 has not been described before. Our review of medical literature suggested this is the first molecularly confirmed case of EVC syndrome in sub-Saharan Africa.
